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"

Well known name in trailer tires. I felt good about ordering this tire/wheel combination. Swapping out a set of ten year old tires with these two were a no brainer. Now set for another ten years.


Exactly what I needed and came earlier than I expected


Tires arrived timely and appeared as described. Will be used on a trailer cooker. Replaced well worn tires.
Time will tell on the longevity of the tires.


I have not installed them yet but the tires and wheels look great. Heavier load rating than my old tires but a good price.


I ordered two new tires for my boat trailer and I tell you that these tires came two days earlier than expected….I have driven my boat now on several fishing trips and no problem at all…..I give them 10 stars


The tires will look great on my trailer. The will look a lot better than the original tires and rims.

The tires and rims still look great. They tow so smoothly. When I finish building my boat trailer I be back to get tires and rims for it to.
Delmar - 02/14/2022


Fantastic product. Exactly the same as original equipment. Kenda has been in business since 1962... and my trailer was built in 1963.

Definitely would buy again


they work greatfor my trailer


Great service and good product got the tires in great time
will be buying more


Planning a trip cross country,well half of it anyway. Needed to update the trailer,so new rubber. Fit perfectly!
Thanks e trailer!


Very quick delivery and product is exactly what I ordered. Quality appears to be satisfactory.


Good tire and wheel for the money


These solved a problem I had with running a trailer with a reasonable load with the tires not performing well, perhaps due to age. These are performing well and I do not anticipate a problem.


Great set of tires. You could save shipping costs of you used a box that was smaller and fit the tires. The box they came in could have held four tires and I only ordered two tires.


Tires and wheels worked out great!


We'll see about the tires, but e-trailer's prompt service was fabulous.


Excellent tires and rims for a small boat trailer, the ones I replaced were old rusty rims and dry rotted tires . Great product and price I checked all over the internet and locally and could not bet the price. The lady took my order was very pleasant and knowledgeable. I got confirmation of my order fast and next day I got shipping and tracking info. etrailer also sent a follow up email to see if every thing was what I had expected and was satisfied .


I wish I could remember the lady’s name who helped me, so I could give her credit. I’m not a trailer expert, so I ended up simply calling etrailer to make sure I got all the pieces I needed for my older flattened spring trailer. So with phone on speaker and a tape measure in hand, I crawled under my trailer and we talked thru what I needed and I confirmed sizes by measuring. I was able to get exactly what I needed the first time. Amazing customer service!


I ordered 2 new tires with rims for my trailer and was pleasantly surprised when the order arrived 4 days ahead of schedule. The tires were packaged in a strong box and everything went perfectly for the installation. The communication from e-trailer was top notch and I would highly reccomend them to anyone.




Exactly as described. Working great and looks great. Fast shipping.


Tires and wheels were received as advertised, quickly and in good shape.


Fast free shipping, wheels and tires fit perfectly. Great communication and package tracking. The cost for wheels and tires already mounted at etrailer was cheaper than just the tires if I bought them locally. Very satisfied.


Replacement trailer tires and rims arrived exactly as ordered. Very satisfied with etrailer and recommend them others seeking similar products. Price, service and delivery were excellent.


Hi, we are very happy with the spare tire for our trailer! We bought the trailer in the online classifieds, needed some work and a spare tire. We found your website had what we wanted and beat our local tire store by $30!
Here’s the finished product! Thanks, again


Great improvement over previous tires.

Very Good. The trailer is high quality and just what I needed. The instruction on the use of the trailer was extremely helpful. Vehicle modification to add the brake assist was done professionally.

  • What Should a 1/2 Inch Lug Nut on a Trailer Wheel be Torqued To
    The valve stems do face out so that is good. You should be using 1/2"-20 lug nuts for tire and wheel combo # AM30120. For a 1/2 inch lug nut, you will want to torque each nut down to 75 to 85 foot pounds. You will want to avoid using an impact wrench or any other tool that cannot provide measured force. Use a torque wrench for accurate results. Make sure that the torque wrench you are using is calibrated correctly. If enough pressure was used it could dent in the raised areas around the...

  • Looking for a Replacement 8 Inch Tire and Wheel Combo with 2.75 Inch Pilot Hole
    All of our 8 inch wheels have a 2.5 inch pilot hole diameter. To determine if they will work on your hubs, you will want to measure the base of the hub bore with a precise measuring tool such as a dial caliper. If the base of the hub bore has an outer diameter that is slightly less than 2.5 inches, then the Kenda Tire and Wheel Combo, # AM30120, will fit. If the outer diameter is exactly 2.5 inches or more, then this wheel will not fit.

  • Trailer Tires for a TeeNee Boat Trailer
    The tire and wheel combo # AM30120 has a 4 on 4 bolt pattern. You would need to make sure you have the right bolt pattern for the wheel to fit your boat trailer. I have included a link to the right that explains how to determine bolt pattern. If you do have a 4 on 4 bolt pattern and 5.70-8 tires then this tire and wheel combo will fit. It is rated for 910 pounds at 75 psi. The tires we carry are rated for 65 miles per hour. You do not want to exceed the speed rating. Trailer tires are...

  • Factors to Consider When Adding Larger Tires and Wheels to a Trailer
    You can add larger wheels and tires to a trailer as long as you have enough room for the larger size. The main clearance issues we find when putting larger tires and wheels on a trailer is from the top of the tire to the fender and from the inside wall of the tire to the trailer wall/frame. The next factor that you will want to consider is the bolt pattern of the wheel. If your current wheels have a 4 on 4 inch bolt pattern, then the new wheels must have a 4 on 4 inch bolt pattern as...

  • Speed Rating of Trailer Tires in Size 5.70-8
    No, unfortunately it is not true that over-inflating a tire allows it to be driven faster, nor can it carry more weight. It is never appropriate to under- or over-inflate a trailer tire for any reason. Trailer tires should ALWAYS be inflated to the maximum cold psi pressure indicated on the tire sidewall. This means that at the start of the day when the tires are cold you want to ensure they have that full specified pressure, no more, no less. It is normal for tires to warm up from friction...

  • Recommended Clearance Between Trailer Frame Rail and Trailer Tire
    The minimum distance between the inside of a tire and the frame rail depends a lot on the setup of the trailer. But as long as the tire and the frame don't touch you would be fine. It's hard to give an exact figure as trailer setups can vary and some trailers may have more side to side movement which would call for more clearance. If the suspension is good on the trailer and not worn out I would go with at least 1-1/2 inches to be on the safe side.

  • What Would Cause Wheel Studs to Break on a Trailer Hub
    Wheel studs can break from too much torque on them or from having them too loose which creates movement which can eventually cause them to break. My brother kept breaking wheel studs on a car he had because he was using the wrong lug nuts. In your situation it sounds like the lug nut torque should have been checked prior to your trip. Typically studs will break one at a time. It almost sounds like one broke and then the movement took the rest out.

  • What Holds the Weight of a Trailer Wheel, the Studs or the Pilot Hole
    Yes, if the pilot diameter of your wheel is larger than the center of the hub then the lug nuts/studs are what is holding the weight of your trailer.

  • Replacement Wheels and Tires for Homemade 1/4 Ton Utility Trialer
    The Kenda 5.70-8 Wheel/Tire combo you mentioned, part # AM30120 would be an excellent replacement. It would be compatible with the bolt pattern, pilot diameter and wheel stud size of your current hubs. The tire is 18 inches in diameter and has a section width of 5.9 inches. The tire has a C load rating, which is good for 910 lbs per tire when properly inflated to 75 psi. For more information about trailer tires, take a look at the Trailer Tire FAQ article I've linked for you.

  • How Often Should Trailer Wheel Lug Nuts be Re-Torqued
    Any time you remove a trailer wheel you have to torque the lug nuts a few times so that they don't back themselves off like what you are experiencing. It is important to re-torque the lug nuts after 10 miles, 25 miles, 50 miles and then monthly after that. It's something that's easy to forget but if you follow that your lug nuts should stop backing themselves off.

  • Recommended Spare Tire For Jayco Pop-up Cmaper With 5.70-8 Tires
    For a spare tire, I recommend the Kenda 5.70-8 Bias Trailer Tire with 8" White Wheel - 4 on 4 - Load Range C # AM30120. I don't see the important info on those tires, but the very similar tires like this spare are rated to be 75 psi inflated cold (meaning before a few miles of road friction warms them up. These tires are also rated to be used at 65 mph max. Looking at your old tires and the price point of these new ones, I recommend you replace your old ones before going cross country....

  • Will Trailer Wheel with 2-1/2 Inch Pilot Hole Fit in Place of a Wheel with 2-3/4 Inch Pilot Hole
    If the center part of the hubs on your trailer are 2-1/2 inches or smaller then tire and wheel combo # AM30120 will fit. A pilot hole can be larger than the hub center diameter if the wheel is held on to the hub with lug nuts. But if it attaches using wheel bolts instead of lug nuts then the pilot hole has to be exact because that is how it centers on the hub. At a 2-1/2 inch hub diameter and wheel pilot hole you would be good to go either way.

  • Recommended Wheel/Tires For 1995 Jayco Pop Up Camper
    I recommend the Kenda 5.70-8 Bias Trailer Tire with 8" White Wheel - 4 on 4 - Load Range C # AM30120 for your 95 Jayco pop up camper weighing 1500 lbs. These wheel/tire combinations will work well and give each wheel a capacity of 910 lbs for a total capacity of 1820 lbs. They have a very nice white powder coat finished wheels over e-coat primer. The wheels have the 4 on 4 inch bolt pattern and meet DOT specifications. They are intended to be inflated to 75 psi cold prior to use.

  • How to Determine the Axle Capacity of a Trailer
    The trailer will have a plate or sticker on it that will list the VIN number. The weight rating of the axle should be listed on that same plate or sticker. Also, the axle could have a tag or plate on it that will list the weight capacity. You can also tell the weight capacity of the axle by measuring the diameter of the axle. Here is a list that will show the axle weight capacity based on the axle diameter: Typical Axle Diameters Based on Axle Capacity - 1,000-lb - 2,000-lb Axles: 1-1/2...

  • Replacing 4.80/4.00-8 Tires with Larger 5.70-8 Tires on a Small Boat Trailer
    With a diameter of 18.1 inches, the new size 5.70 tires will be about an inch closer to the fender than the current size 4.80/4.00-8 tires, which have a diameter of 16.1 inches. This will leave you about 3-1/2 inches of clearance between the top of your tire and the underside of the fender based on the information you provided. For such a lightweight boat like yours, this should leave plenty of room for debris and suspension travel. The Kenda tire, # AM30120, that you mentioned should...

  • Will Trailer Wheel and Tire # AM30120 Fit Hub with Center Section that Measures 2-1/2 inches
    If the center section of your hub is 2-1/2 inches wide and all of the other things you mentioned of the Kenda 5.70-8 Bias Trailer Tire with 8" White Wheel # AM30120 match this will fit and work well for you. The center hole of the wheel will fit right over the hub and fit just fine. In a lot of cases the pilot diameter is a bit bigger than needed, but in your situation where it fits exact it will work just fine. If anything it will make lining up the wheel on the lugs a bit easier.

  • How to Determine 4 Bolt Wheel Bolt Pattern
    We don't have your exact bolt pattern as you listed it. Most likely you have a 4 on 4 inch bolt pattern though. Are you measuring from wheel stud center to wheel stud center across the pilot hole of the wheel? I attached a help article that covers determining bolt patterns as well.

  • What is Pilot Diameter of Kenda 5.70-8 Bias Trailer Tire with 8" White Wheel # AM30120
    The pilot diameter of the Kenda 5.70-8 Bias Trailer Tire with 8" White Wheel # AM30120 that you referenced is right at 2.5 inches. As long as the center portion of your hub measures less than that the hub will fit. Basically as long as the pilot diameter is big enough to fit on the hub this wheel will work just fine.

  • Speed Rating for Kenda 5.70-8 Bias Trailer Tire with 8 Inch White Wheel # AM30120
    All of the trailer tires we carry are now rated for 65 miles per hour. The load range of a tire does not change its speed rating, so a B load range will have the same 65 mph speed rating as a C load range. For the Kenda 5.70-8 Bias Trailer Tire, # AM30120, that you have referenced, the tire has a capacity of 910 pounds at 75 psi. Trailer tires should be inflated to their maximum indicated psi rating for best performance and longer life.

  • How Much Clearance Do I Need Between Tires and Fenders on Trailer?
    This is a great question. You generally want to allow 3" clearance between the top of the tire and the fender (or bunk), at minimum, when your trailer is fully loaded. This should give you adequate clearance for potholes and bumps. In order to get a precise measurement on an underslung trailer (the springs are mounted under the axle), you should measure the distance between the bottom of your frame and the top of your axle. Add two inches to that measurement and you'll have adequate clearance...

  • Is It Really Necessary to Re Torque Trailer Lug Nuts After Mounting the Wheels
    It's a pretty common practice to torque the lug nuts of a wheel to the recommended value and then check the torque value again after 50 to 100 miles to ensure they are still at spec. I've actually chosen to ignore the recommendation when I was younger and lost lug nuts on my car as the lugs had worked loose. Basically you tighten them down, and after you drive a bit sometimes the wheels settles differently and the lug nuts aren't uniformly torqued down anymore. You are obviously free to...

  • Solution for Tire Sidewall Rubbing Against Trailer Frame
    If the inside of your trailer tire is rubbing against the frame on your trailer then you can either get a new trailer axle that has a larger hub-face measurement or get slightly smaller tires. The easier solution would be to swap out your tires for smaller ones. We recommend at least 2" of clearance between the tire and the frame so you'll want to keep that in mind. Let me know what your current tire size is as well as your bolt pattern (see attached article) and the GVWR of your axle...

  • Is It Important for Hub Pilot and Wheel Pilot Diameter to Match
    The answer to your question depends on whether your current hubs are lug or hub centric. A lug centric hub uses wheel studs and lug nuts to retain the wheel to the hub. As long as the hub fits through the pilot diameter of the wheel, it does not matter if the pilot diameter is larger. A hub centric wheel, on the other hand will use lug bolts to attach the wheel, and the pilot diameter will matter because the portion of the hub that protrudes through the wheel pilot provides some support...
