Radial Tires vs. Bias Tires

Radial tire vs bias tire graphic

Radial ply tires are designed for trailers that are towed on the highway. The cords on a radial tire are positioned at a 90-degree angle to the direction of travel so that they lay across the width of the tire from wheel lip to wheel lip. This construction prevents the cords from rubbing against one another when the tire flexes, unlike the cords on a bias ply tire. As a result, radial tires have less rolling resistance and heat buildup, which leads to a longer tread life and improved steering at higher speeds.


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"

  • Changing Boat Trailer Wheels from 12 to 13 Inch Diameter
    For a 13 inch wheel and tire combo, the tire sizes would either be ST175/80-13 or ST185/80-13. The 175/80-13 measures 24.02 inches in diameter, while the 185/80-13 measures 24.65 inches in diameter. This is considerably larger than the 4.8-12 wheel and tire that has a 20.5 inch diameter. The wheels on these combos are typically 4-1/2 inches wide, with the alloy wheels being 5 inches wide. If your boat trailer can accommodate the larger diameter and width without having any clearance problems...

  • Can Radial Tire be Used in Place of Bias Ply Tire on Boat Trailer
    Radial tires can be used instead of bias tires on a trailer. If most of your driving is highway driving they would actually be preferred. Radial tires have better ground contact and run cooler. A bias tire can be more useful if you're towing your trailer off-road a lot because they have a stiffer sidewall. Generally, for a boat trailer you're better off going with a galvanized wheel, like # AM31994, because of the rust resistance. I've linked our selection of 175/80-13 sized tires...

  • What Type of Tire Should be Used on a Motorcycle Trailer
    Some tires are specially designed to be used on trailers. These tires include the letters "ST" in the size specification that is listed on the sidewall. The "ST" stands for "special trailer". This kind of tire has a stronger sidewall than an automobile or truck tire so it can handle higher air pressures and higher loads. For a trailer I cannot recommend you use a passenger vehicle tire regardless of how small or lightweight the trailer is. The main difference between a radial ply and...

  • Do the Trailer Rim and Tire Combinations Come Balanced
    The trailer tire and wheel combination is received from the supplier already with the tire mounted on the wheel. The supplier does not balance the combination, but when the tire is installed to the wheel they will line the high (heavy) spot on the tire with the low (light) spot on the wheel. This does not completely balance the tire and wheel combination but it does eliminate any excessive out of balance condition. I would recommend to balance the tire and wheel combination at a local...

  • Does Karrier ST175/80R13 Radial Trailer Tire Come Balanced
    The tire and wheel combos we carry like the part # AM31994 are not machined balanced. You can have the tire and wheel combos balanced at a local tire shop if you wanted to. What our tire manufacturers will do is line up the light spot on the tire with the heavy spot on the wheel. This is a type of balancing but not like how car tires are balanced (with weights on a balancing machine).

  • Are Kenda Karrier Trailer Wheel/Tire Combos Factory Balanced
    The wheel and tire combos we sell are not balanced at the factory. When the tire is mounted to the wheel, the high (heavy) spot on the wheel is matched to the low (light) spot on the tire, which leaves the wheel and tire somewhat balanced. You may have the wheel/tire professionally balanced if you wish, but having perfectly balanced tires is not as important with trailer tires as it is with a passenger vehicle. I have linked you to our Tire and Wheel help article that contains more helpful...

  • Can ST175/80R13 Radial Trailer Tire Replace 165/80-13 Size Tire on Boat Trailer
    Your current 165/80-13 size tire has a section width of about 6.5" and an overall diameter of about 23.4". The Karrier ST175/80R13 Radial Trailer Tire with 13" Galvanized Wheel # AM31994 that you referenced has a section width of 7" and an overall diameter of 24.1". This means that you need to have room for at least 0.25" of tire width-wise and about 0.50" height-wise. As long as you have that then this new tire will work great!

  • Can 12 Inch Trailer Tires and Wheels be Replaced with 13 Inch
    The smallest diameter 13 inch trailer wheel and tire will have a diameter of 24.1 inches (ST175/80-13). There are 3 common 12 inch trailer tire sizes: 4.80-12 has a diameter of 20.5 inches, 5.30-12 has a diameter of 21.9 inches, and 145/80-12 has a diameter of 21.3 inches. So basically the overall difference between the two sizes, depending on the specific 12 inch size, is between 2.2 inches and 3.6 inches. Half of the difference applies to the bottom of the tire from the center of the...

  • Do Trailer Tires Come Already Balanced
    The pre-mounted trailer wheel/trailer tire products we sell, such as # AM31994, are not dynamically balanced the way vehicle wheels/tires are. Trailer tires do not really need to be fully balanced the way vehicle tires do but you could have them balanced if you wanted. These items are mounted together so that the wheel's heavy spot mates up to the tire's light spot; this is not the same as a full dynamic balance but it is fine for trailer use. The two linked articles on trailer tires will...

  • What is the Weight Rating Of My 175/80D-13 Tires
    Since this tire is 175/80-13 bias tire, tires of this size have weight ratings up to 1,100 to 1,610-lb maximum load at 65 psi. This information is based on current tires we sell that are the same size like # AM31994. So the rating that I listed is not promised to be accurate, but this information can be used as a guide. If you are trying to determine the load capacity of the trailer you will need to use the axle to determine that. The easiest way is to look for a plate or sticker somewhere...

    We don't have anyway to look up the tire size of your trailer. I'd need you to get me the tire size stamped on the sidewall of the trailer and the wheel bolt pattern of your current wheels. I attached a help article that covers determining bolt pattern for you to check out as well.

  • Is it Necessary to Fully Balance Trailer Tires
    First, thank you for your many purchases from us here at etrailer, including the Kenda Karrier tires # AM31994. Trailer tires that we sell come from the distributor already mounted to the rims. These do NOT get a full dynamic balance the way new vehicles tires do but they don't actually need this. When the tires are mounted to the rims the light spot on the tire is matched to the heavy spot on the wheel. This provides a degree of balancing that is sufficient for trailer tires. You can...

  • Can 13 inch Trailer Wheel and Tire Replace 12 inch Size 5.30-12
    The wheel and tire from Karrier part # AM31994 would work well for you. It's a 13 inch wheel with the tire size of 175/80-13 and a bolt pattern of 5 on 4-1/2 inch like you need as well. The pilot diameter is 3.19 inch too which is slightly larger than what you have now but will still work great. Overall diameter of the tire is 24.1 inches and the section width is 7 inch. You might compare that to what you have to make sure you have the additional clearance. Your current tire diameter is...

  • Solution for 14 Inch Tires Rubbing Against the Fender
    We do not recommend using spacers because it can cause otherwise avoidable issues with your tires and hubs. There are not smaller 14 inch tires and because you do not want to remove the fenders the best option is going to be replace both your wheels and tires with a smaller capacity. The most important thing to know before doing this is what your hub's bolt pattern is. The most common is 5 on 4-1/2" although if you are unsure you will need to take some measurements to find out and I have...

  • How to Measure Bolt Pattern to Pick the Correct Wheel
    It sounds like you may have measured incorrectly, though you were on the right track. There are actually a couple of ways for you to find your bolt pattern. The first way is to measure from the center of one lug to a point halfway between the two lugs directly opposite on the bolt circle. The other method would be to use the distance between the center of one bolt hole to the center of the bolt hole adjacent to it. If the distance is: 2-5/8" - the bolt pattern is 5 on 4-1/2 2-3/4" - the...

  • Can a Smaller Tire be Used With Snowmobile Trailer?
    The ST205/75R14 tires you have are designed to fit on 14" wheels, and there are no tires which would be shorter you could use on 14" wheels. What you would need to do instead is get a new wheel and tire combination that would allow you to use a smaller tire but still have the right load capacity. To do that you would need to know your wheel's bolt pattern; I've added a link to a help article which details how to determine your bolt pattern. If you have a 5 on 4-1/2 bolt pattern, which...

The narrower 155 tire is 155mm (6.1-inches) wide and has an overall diameter of 22.7-inches. The wider 175 tire is 175mm (6.9-inches) wide has an overall diameter of 24.1-inches.

    The Karrier ST175/80R13 Radial Trailer Tire with 13" Galvanized Wheel - 5 on 4-1/2 - Load Range D # AM31994 will fit on a single yacht club jet ski trailer that has a bolt pattern of 5 on 4-1/2 inches. You will want to make sure that you have the proper clearance as these tires are 24.02 inches in diameter and 6.97 inches wide so you will need about 4 inches from the center of your tire to the frame.

These galvanized wheels will not corrode and the tire/wheel combinations are rated for a max load of 1,610 lbs at 65 psi.
