Bias Tires vs. Radial Tires

Bias vs. radial tire graphic

Bias ply tires are designed for off-road or agricultural applications. They are built with thick, durable nylon cords that are positioned at a 30- to 45-degree angle to the direction of travel. The layers alternate in a crisscross pattern, making the sidewalls stiffer so that the entire tire is able to flex easily. As a result, the tire provides a smooth ride and improved handling when trailering on uneven surfaces.

Determining the Bolt Pattern

The first number in the bolt pattern is the number of bolt holes. The second number denotes the diameter, in inches, of the circle on which the bolt holes sit.

Bolt Pattern - Odd

To determine the bolt-circle diameter on wheels with an odd number of bolt holes, measure from the center of any bolt hole to the point halfway between the two bolt holes directly across from the first. (Example: "5 on 4-1/2" means 5 bolt holes with 4-1/2" measured to a point halfway between the opposite bolt holes.)

Bolt Pattern - Even

On wheels with an even number of bolt holes, measure from the center of one bolt hole to the center of the hole directly across from it. (Example: "8 on 6-1/2" means 8 bolt holes with 6-1/2" from the center of one hole to the center of another on the opposite side.)

Bolt Pattern - Side

Measuring the distance from the center of one bolt hole on the wheel to the center of a bolt hole right next to it can also help to determine the bolt pattern.

  • If D = 2-5/8", then the bolt pattern is 5 on 4-1/2"
  • If D = 2-3/4", then the bolt pattern is 5 on 4-3/4"
  • If D = 3", then the bolt pattern is 5 on 5"
  • If D = 3-1/4", then the bolt pattern is 5 on 5-1/2"

Average Customer Rating:  4.8 out of 5 stars   (5986 Customer Reviews)

Bias tire has a ply rating of 6 and a 1,045-lb maximum load at 80 psi. The 12" diameter x 4" wide steel trailer wheel features a 5 on 4-1/2 bolt pattern and a corrosion-resistant galvanized finish.


Tires look great, the wheels have some bubbling in the galvanized finish identical to what other review photos show. Otherwise the price is perfect for a trailer that sits most of the year. Great replacements for the original tires/wheels on my 04 Snowbear utility trailer. I preferred the galvanized look over the white wheels with pin stripes.


Bought one as spare 3 months ago. So much better then what trailer has as stock wheels and tires. So I bought another to replace both wheels and use old ones for two spares.

Got some wheel locks too.

Excellent! Service! I needed this ASAP as I’m in the road and it arrived fast as light! Thx Savana and crew !!

James R.


Great wheels. Actually just sold trailer and the wheels and tires did it.


Exactly what I ordered, love the emails after order to let me know my order was received and tracking info!!! Definitely will order from etrailer again also love the free shipping over 99 bucks



They work fantastic Very happy


Very fast delivery
Secure shipping packaging

Have not had time to
Open packaging or evaluate boat trailer wheels yet.
Everyone at etrailer has been great to work with and to address my needs.
I manage and maintain over several boat trailers so I need to hsbe a reliable source of parts and products.
So far has met my needs promptly and efficiently!!


I buy regularly from to support my business. has performed in an excellent manner over the 4 years i a have used them.


I don't normally write reviews but etrailer staff went out of their way to help so I will put in my two cents. Have only had the wheels/tires for a few days but look pretty good for the price. Will say that the welded seams are a little rough, but appear sturdy.

My boat trailer was stored at previous owners yacht club as a dolly since 96 and most everything rusted out. I now realize I should have picked up a hub kit from etrailer with this wheel/tire combo but had already had a local mechanic replace all bearings/races/seals but tire code was 2004 even though they looked great. About to go on a road trip with the boat/trailer and tires were too old so this new set got me on the road economically and the rims are galvanized as trailer will mostly be in the salt. Got new lug nuts for marine application as well as advised by etrailer associate on the phone. I would advise anyone to call etrailer with questions as they definitely know customer service.

Handy "how to measure" etrailer guide worked out great and I did have the 4.5" 5 lug model so it was a perfect fit. Unfortunately, when torqued to the 75-85 lbs recommended in the etrailer torque guide one wheel lug pulled right through although I think it's just that its time had come. etrailer had the part but I needed it quick and picked it up locally and am ready for my trip.

Not my first time visiting, wont be my last. Not sure if I can update this review, but will try if any wear/durability problems with the Kenda tires.


Awesome wheel and tire combo, year later look like new buy again in a minute. Happy camper


The wheel bearings on my utility trailer gave out and the local Les Schwab wanted an arm and a leg to replace them. They also noted the tires were at the local tread limit and needed to be replaced. So I went searching for lower cost alternatives.

I found on a google search and was impressed by their selection, low pricing and expert help on their website. I ended up ordering two Kenda 5.30-12 Bias Trailer Tire with 12" Galvanized Wheel - 5 on 4-1/2 - Load Range C and two Trailer Idler Hub Assembly for 2,000-lb Axles - 5 on 4-1/2 - Galvanized from etrailer, and also a set of Reese Towpower 74177 Wheel Bearing Protectors from Amazon. My total cost was LESS THAN the price Les Schwab quoted me for bearing replacements for the two wheels.

They are all on my trailer and and look great. I am really impressed by the quality of parts from etrailer and also their great pricing. Give them a try!

Tires and wheels are holding up well, very satisfied with my purchase. Will buy again from eTrailer and also recommend to my friends.


No nuts for spare tire carrier! And rim is all rusted and bubble up

While you are right that it does not come with extra hardware, it should not have been rusted. I will have our customer service team reach out to you about this.


Worked out perfectly. Inflated to recommend psi and drove the trailer fully loaded for a 1600 mile trip


Price was good and shipping was fast, but the finish on these rims (even for the price) is lacking, in my opinion. I didnt' expect a chrome-like finish from galvanized but these things are not something to be proud of. Every one of the 4 I purchased has what appear to be rust spots under the galvanization. Two of them have spots where the galvanization does not seem to have adhered properly. While maybe they will hold up OK for a while, the main reason I purchased new tires AND wheels was because my existing wheels were looking aged. These don't look much better.


Order came in on time and well packaged. My trailer is a 2004 and the new tires and rims made it look much better


Just needed a spare for my atv trailer. Found easily on etrailer site. Fair price and was delivered extremely fast with standard shipping


Product looks very good. The galvanized rim is perfect for my application. Also the price was very competetive. Thanks!


Excellent service; product is exactly what I needed. Etrailer is the go to place for trailer needs.



Great. I have always been happy with the etrailer tirewheels. They look and work well. No complaints. Thank you!


Tire and wheel was exactly what I ordered order was processed and shipped quickly.


Shipping is the problem.. When the order was placed it was promised deliver in two days. The wheels came in two days UPS without issue. However, the Wheel bearing kits were not sent with the wheels but in a separate box by USPS and is not due for an additional four days. The quick shipping on the wheels is no good without the wheel bearings. Plenty of room in the box to place two wheel bearing kits. Very disappointing.


Wheels received promptly and as advertised. Tire mfg dated June 2022, so already a year old or would have rated 5 stars.


Excellent tires and wheels and outstanding shipping and service. Will only buy all my trailer stuff from here.


Wheel and tire look good on trailer


Have owned these for a year and so far they've been great. No issues whatsoever, would recommend if you're looking for a good replacement.


The tires and wheel were installed onto a snowcat, as replacement 'roller wheels'. So, not a trailer application for my use.


Explored many different options for this project, came back to this vendor for ease of site, product offerings, and pricing value. Received the product as expected and delivered on time as indicated. The wheels and tires were found to be as advertised, no surprises, overall an excellent experience.


Shipped fast. Always do.


Shipped same day as ordered. Very quick delivery. Impressed

  • Are Carlisle 5.30-12 Tire, Load Range C, the Same as Kenda Loadstar 5.30-12 Tire, Load Range C
    The Carlisle 5.30-12 tire and the Loadstar 5.30-12 Tire, # AM30850, are very similar. They are the same size and have the same load range rating (load range C). A tire with a C load range should have a ply rating of 6. So in size, load range, and ply rating, they have the same specifications. A tire can have a 6-ply rating (load range C) and not necessarily have 6 plies listed on the sidewall of the tire. The ply ratings were introduced when tires used cotton layers to strengthen a tire...

  • What is the Speed Rating on a 5.30x12 Trailer Tire
    Many times, trailer tires do not have a speed rating. The tires that we carry are rated for up to 65 miles per hour unless otherwise indicated on the tire sidewall. Since 185/80-12 is not a common trailer tire size, it would require going to a 13 inch wheel and you may or may not have clearance around the tire for the larger size. There is a 145/80-12 trailer tire size that will be about a half inch wider than a 5.30x12. I have included a link to them for you to view and a link on trailer...

  • What Are The Torque Specs And PSI Rating For Kenda 5.30-12 Galvanized?
    It looks like your Kenda 5.30-12 Bias Trailer Tire with 12" Galvanized Wheel - 5 on 4-1/2 - Load Range C # AM30850 uses 1/2" lug bolts/nuts. If this is correct, then the correct torque specs would be 75-85 ft.-lb. If you are using something other than 1/2" lug bolts/nuts then use the chart I attached which shows the various torque specs. It is recommended to inflate trailer tires to the max psi, in this case, 80psi. If the tires are under-inflated then you could risk a blow out and the...

    The shipping weight of the Kenda 5.30-12 Bias Trailer Tire with 12" Galvanized Wheel # AM30850 that you referenced is 21 lbs. If you take about 3 lbs away for shipping packaging that leaves you with 18 lbs that will be on your spare tire carrier.

  • Can I Replace My Wheels With Wheel/Tire Combo with Larger Bore Diameter
    The Kenda 5.30-12 Bias Trailer Tire with 12" Galvanized Wheel - 5 on 4-1/2 - Load Range C part # AM30850 is a lug-centric wheel which means it attaches by the lugs not the bore/pilot hole of the wheel. The existing wheel having a smaller bore diameter will not make a difference. As long as the bolt pattern is 5 on 4-1/2 and your existing wheels are 12" you will not have any issues using these wheels or with alignment and balance. Wheels used to be hub centric, which means they balanced...

  • Does Kenda 5.30-12 Bias Trailer Tire with 12" Galvanized Wheel # AM30850 Come with Valve Stems
    Yes, the Kenda 5.30-12 Bias Trailer Tire with 12" Galvanized Wheel # AM30850 does come with valve stems and is inflated. You will need to check the tire pressure before you install the wheel though. Make sure it is inflated to it's max psi rating of 80 psi to get it's full 1,045 lb capacity.

  • Is The Kenda 5.30-12 Bias Trailer Tire with 12" Galvanized Wheel Available in Radial Instead of Bias
    We do not have a radial tire available in 5.30-12. and you will likely have a hard time finding one. The radial equivalent of the 5.30-12 is the ST145/R12. There is the Kenda 5.30-12 Bias Trailer Tire with 12" Galvanized Wheel # AM30850 you were looking at for the 5.30-12 bias tire or the Kenda Karrier S-Trail ST145/R12 Radial Tire w/ 12" Galvanized Spoke Wheel # AM31202 for the ST145/R12 radial tire.

  • Taller Tire Solution for Trailer to Replace 5.7-8 Size
    1 inch of clearance between the frame and the inner sidewall is the minimum that is recommended so your best solution is to not go with a wider tire but a taller one if possible. A 5.30-12 tire and wheel like the Kenda 5.30-12 Bias Trailer Tire with 12" Galvanized Wheel # AM30850 would accomplish this as it's about 3 inches taller and actually narrower.

  • Correct Torque Rating for 12" Steel Trailer Wheel
    Your tire should mount via 1/2"-20 lugs like what we see with the Kenda 4.80-12 Bias Trailer Tire with 12" White Wheel - 5 on 4-1/2 - Load Range C # AM30660. For this size and style (steel) of wheel you need to torque the lug nuts to be inside the 75-85 ft-lbs range. I'm attaching a chart we have which shows the various torque ratings for different wheel styles and sizes.

  • Replacement Wheel And Tire Compatibility For A 2010 Triton Pontoon Trailer
    The Kenda 5.30-12 Bias Trailer Tire # AM30750 would technically fit your trailer but it has a lower load range so you'd want to go with the Kenda # AM30850 instead to maintain your load range C capacity.

  • Is a 5.30-12 and a 5x4.5 Trailer Tire/Wheel Common
    5.30-12 is a pretty common trailer tire size, whereas 5x4.5 is a very common wheel bolt pattern but not actually a tire size. For example the wheel and tire part # AM30850 is a 5.30-12 tire size mounted on a wheel with a 5 on 4-1/2 inch bolt pattern.

  • Replacement Trailer Tire and Wheel for 5.30-12C
    As long as your current wheels have a 5 on 4-1/2 bolt pattern then yes, the Kenda 5.30-12 Bias Trailer Tire with 12" Galvanized Wheel - 5 on 4-1/2 - Load Range C # AM30850 will work perfectly. These tires have the same specs as your existing setup, but the wheels are 12" x 4", so they are slightly more narrow than a 4.25" wide wheel you've mentioned. This shouldn't affect any functionality of use or compatibility issues and we do not have any 12" wheels that are 4.25" wide.

  • Benefits of Upgrading to 5.30-12 or 175/80-13 Tires On a Boat Trailer
    The benefits of upgrading to larger tires are better weigh ratings, higher speed capacity, larger wheel/tire selection as well as reduced wear/tear on the hubs. If you have the needed space then this is a great option. The 5.30-12 tires are 21.9" diameter x 5.6" wide, I recommend the Kenda 5.30-12 Bias Trailer Tire with 12" Galvanized Wheel part # AM30850. The 175/80-13 tires are 24.1" diameter x 7" wide, I recommend the Karrier ST175/80R13 Radial Trailer Tire with 13" Galvanized Wheel...

  • Recommendation for New Tires and Wheels on Boat Trailer with 5.30-12 5 Lug
    My personal recommendation would be to go with a load range C tire like the Kenda 5.30-12 Bias Trailer Tire with 12 inch Galvanized Wheel, # AM30850, or the # AM30820 with white wheel. The class C tire offers a higher load capacity than that of the class B tire and may be beneficial when hauling your boat. Keep in mind that although you would be increasing the load capacity on your tires, you are still limited to the lowest rated component on the trailer. I spoke with my in-house tire expert...

  • Product Differences Between Wheel and Tire Package AM30850 and AM30861
    The Difference in these two packages is the tires that are on them. The load ratings are different and thus will each respond different when driving. I suggest going with the tire that your trailer is specified to use. # AM30850 Utilizes a Load Range C tire that has a wheel capacity of 1,045lbs. Max inflation pressure is 80psi, which gives this tire more absorption when driving which will equal a smoother ride. # AM30861 Utilizes a Load Range D tire that has a wheel capacity of 1,250lbs....

    If your Shorelandr boat trailer has a 5 lug wheel, it'll have a 5 on 4-1/2 inch bolt pattern but if you wish you can measure it. This is really simple to do, just measure the distance between two adjacent wheel studs, center to center. If the distance is 2-5/8 inches, then you've confirmed it's a 5 on 4-1/2.

  • Suggested Spare Tire For a Haul-Master Trailer
    From what I could find out about the wheels on the Haul-Master trailers, they do utilize a 5.30-12 tire and wheel combo. The Kenda 5.30-12 with 5 on 4 1/2 bolt pattern # AM30740 will definitely fit. That being said, it does have a B weight rating, which means it is rated to 840 pounds. The tires that come with the Haul-Master tires look to have a C rating, which will be 1,045 pounds. A few better options will be the Kenda # AM30850 with a C rating (1,045 pounds), or the Kenda # AM30859...

  • Can Trailer Tire Size 4.80-12 be Replaced with 5.30-12
    Yes, you can as the size is very similar and it's a very common tire size change. So if you had a 5 lug wheel currently you could use the part # AM30850 or for a 4 bolt wheel you'd want the part # AM30790 which also has a galvanized wheel and same tire. Or you could reuse your current wheels and mount the part # AM10066 to it.

  • Replacement Options For An ST155/80R13 Boat Trailer Tire
    A 5.30 x 12 tire would be too small to fit your 13" wheels so you would have to either replace the wheels as well or size up to a 175/80R13 tire and check to ensure that there's enough clearance between the tire and the frame and fenders of the trailer. For a 5.30 x 12 tire and wheel you can use part # AM30850 if you have a 5 on 4-1/2 bolt pattern or part # AM30790 if you have a 4 on 4 bolt pattern. The options in this size are all bias ply.

With that number you would select a tire and wheel that has a capacity rating of roughly 1/2 of the GAWR. Selecting a combination that is rated slightly higher than the axle would be better than selecting one that is lower in capacity.
