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"

  • Difference Between Mini Mod Trailer Rim and Non-Mini Mod Trailer Wheel
    The difference between the two rim designs you mentioned is just a visual difference. The mini mod wheels are a white rim that have small circles that run around the mounting flange of the rim whereas the other white style you referenced has triangles cut out instead. I attached a picture that shows the difference between the two styles with the mini mod being labeled. The rims in the picture are # AM31985 and # AM31991.

  • Can Trailer With ST145/R12 Tires be Upgraded to 13 Inch Tires
    We have ST145/R12 trailer tires with a load range E, the Kenda Karrier S-Trail # AM10140. If you wanted to go to a larger tire and wheel you could do so but you would need to ensure you have the needed clearance of about three inches from your trailer tire to rim and four inches to your trailer frame. A ST145/R12 tire like the Kenda Karrier S-Trail # AM10140 measures 21.3 inches in diameter when inflated and is 5.7 wide. The smallest 13 inch tire is ST175/80R13 quite a bit bigger, measuring...

  • Can ST175/80R13 Be Used On One Axle and ST185/80D13 Be Used On Other Axle Of 2013 Jayco TT?
    It is not recommend to mix tire sizes on a trailer, as it will cause the trailer to sit unevenly and put additional pressure on one axle. Now in addition your ST175/80R13 tires are radials where the ST185/80D13 are bias ply and these should not be mixed either. These tires have different ply designs and handling characteristics and mixing them on the trailer will cause a very unpleasant and unstable towing experience. I recommend going ahead and purchasing a ST175/80R13 spare as it is...

  • Recommended Replacement Axle To Fit 205/75R15 Tires On 5x8 Ultra-Tow Aluminum Trailer
    I would be happy to go over the available options. Starting with changing the axle I recommend going with the Timbren Heavy-Duty Axle-Less Trailer Suspension 2,200 lbs # ASR1THDS01 which would give you 6" from the hub face to the trailer frame which is plenty for the ST205/75R15 wheel and tire combination you purchased. You could go with a 3500lb option but there is not a hub available for it with a 5 on 4-1/2" bolt pattern, and since you would be quite a bit under the weight you would...

  • Will ST175/80R13 Tire Fit Harbor Freight 1720 Trailer
    The main issue when switching from a 5.30-12 tire to the Karrier ST175/80R13 Radial Trailer Tire w/ 13" White Mini Mod Wheel - 5 on 4-1/2 - Load Range D # AM31991 is going to be clearance. It looks like you have a fender on the Harbor Freight 1720 so you will have to measure and potentially remove if if you want to use the larger tire. The # AM31991 has an outer diameter of 24.1" and a section width of 7". When compared to something like the # AM30790 with a 5.30-12 tire you will lose...

  • Are Trailer Tires Already Balanced on the Wheels on the Tire and Wheel Combinations?
    Trailer tires do not have to be balanced due to the fact that you won't be able to feel the imbalance in the vehicle. Every tire and every wheel has a high (heavy) spot and a low (light) spot. When the manufacturers mount the tires on the wheels, they try to offset the tire high spot and the wheel high spot to provide some balance. You can take them to a tire shop and have them balanced if you want them to be balanced, but they do not need to be balanced to be used on your trailer. Many...

  • Looking for Smaller Diameter Replacement Tire for Bass Boat Trailer
    By looking at the photo you provided, I can see that you do indeed have a clearance problem with the fender. Going to a 13 inch wheel/tire combo like the Kenda Wheel/Tire Combo part # AM31990 for a black mod wheel or # AM31991 for a white mod wheel would improve your clearance issue to a degree. Both wheels have a 5 on 4-1/2 wheel bolt pattern, and both feature a ST175/80-13 Load Range D tire that has a 1650 lb weight rating per tire/ 3300 lbs per axle when properly inflated to the maximum...

  • Options to Replace 175/70R13 Trailer Tires With Wheel
    We do not offer 175/70R13 tires, as those are generally passenger tires. The closest match to that is 175/80R13 which measure 24" in diameter and 6.9" wide, such as the Karrier ST175/80R13 Radial Trailer Tire w/ 13" White Mini Mod Wheel - 5 on 4-1/2 # AM31991.

    With your 2015 Shasta Airflyte Retro trailer having a ST225/75R15 Radial Tire with 15" Wheel # AM32545 you are going to have 10" brake drums. The smallest wheel and tire that will fit a 10" drum with a 5 on 4-1/2" bolt pattern is going to be the Karrier ST175/80R13 Radial Trailer Tire w/ 13" White Mini Mod Wheel # AM31991.

  • Can I Use Radial and Bias Tires at the Same Time?
    If this is just a temporary spare, you can but not for long. We recommend running the same type tire on both sides for safe towing because the different types will respond differently on the road. We need each tire on your trailer to handle the same so we don't have issues on the road. If you decide to go with both bias tires then you need Item # AM3S331. If you want to go with radials you need Item # AM31991. I have radials on my trailer! Radials have more flex to them. Radials grip...

  • Difference Between a P155/80R13 and a ST175/80D13 Tire
    I have an answer for you to clear of some of the differences. If you have the tire size of P155/80R13, the "P" stands for passenger car tire and the "R" stands for radial tire. The radial means the way the steel cords/plys are layed in the rubber. With the ST175/80D13 Tire like the # AM1ST77, the "ST" stands for special trailer tire and is only compatible with trailers. The "D" stands for diagonal pattern. We do sell a similar radial version of the ST175/80D13 as tire # AM31991. This wheel...

  • Availability of Smaller Tire to Lower Trailer With 205/75R15 Tires
    If you want to lower your trailer by 1" you will need a tire with an outer diameter that is 2" less than your current tire. An ST205/75R15 tire like the # AM10244 has an outer diameter of 27.3". In order to reduce the size enough you will have to use a 13" tire like the # AM31991. The outer diameter of this tire is 24.1" so it is 3.2" smaller when compared to the 205/75R15 tire so it will drop your trailer 1.6". You will also need to make sure the capacity can still handle your trailer....

    An ST145/R12 tire like the Kenda Karrier S-Trail # AM10140 measures 21.3 inches in diameter when inflated and is 5.7 wide. The smallest 13 inch tire is ST175/80R13 quite a bit bigger, measuring 24.1 inches in diameter and 7 inches wide. You'll need to measure to determine if you have clearance. If so, and if you have a 5 on 4-1/2 inch bolt pattern there are a number of options available for this tire with different styles of wheel (if you are unsure of your exact bolt pattern you can...

  • Are The Wheel and Tire Combinations Balanced Already?
    The tire and wheel combos we carry are not machined balanced. The reason manufacturers do not balance their tires and wheel assemblies like the Karrier Tire and Wheel Combo # AM31991 is because a balanced tire and wheel is not very necessary on a trailer. They do not use drive or steering axles, so they are basically just supporting a vertical load and trailing a tow vehicle and balancing won't do much to improve that or necessarily make the ride more comfortable.

  • Need Replacement Trailer Tires for Size R78-13 on a 1989 Palomino Pop-up Camper
    The old tire size of 78-13 is going to be either a 175/80-13 or a 185/80-13. Since you mentioned that the tires were different sizes I would assume that you potentially need to also replace the wheels. There are 2 different bolt patterns for the wheels in these sizes; 4 on 4 or 5 on 4-1/2. So if it has 4 lug nuts holds on the wheel then it is a 4 on 4 and 5 lug nuts would indicate a 5 on 4-1/2. I have linked all of the tire and wheel combos in both tire sizes for you. The tires you choose...

  • 175/80-13 Load Range D Bias or Radial Trailer Tire for Highway Use
    I've linked our selection of 175/80-13 sized tire and wheel combos for you but it sounds like you've already looked through them. Since your trailer will mainly be on the highway I definitely suggest going with radials like # AM31991. Radial tires run cooler than a bias tire, and a cooler tire will last longer. They also have better ground contact, traction, stability, and tread wear which will benefit you on highway use. A bias tire is generally only a better option for off road...

  • Bias vs Radial Tires for 2002 Viking 2470ST Pop-Up Camper
    Since radial tires flex more than bias tires, they generally have better ground contact, traction, stability, and tread wear. They also run cooler than bias tires do, especially when under a load, so radials tend to last longer. While bias ply tires can be useful for off-road applications like farm use, radials are generally preferable on the highway and for long trips. Given your usage, I'd suggest upgrading to a radial tire. I've attached a helpful article on trailer tires for your convenience....

  • Proper Tire Pressure for Trailer Tires
    You should not run your tires at 50 psi if their max rating is 65 psi. Trailer tires such as the Karrier # AM31991 always need to be filled to the max psi for the best performance, while reducing the air pressure is going to lessen the load you are able to carry, making the tire's performance uneven and heightening the risk of a blowout.
