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"

  • Increasing Wheel/Tire Size on Carry-On Utility Trailer
    You do indeed have a 12 inch rim. When you measure the diameter of the wheel, you'll need to measure the diameter of he wheel where the tire bead meets the wheel. I've provided you a cutaway diagram of a wheel showing where the measurement would be taken. Given the tire size, you have a 12 inch rim. There are a few things you'd need to check before going with the larger 13 inch wheel w/ 175/80-13 tire. The 175/80-13 tire is approximately 3-1/2 inches larger in diameter, which would bring...

  • Will a 175/80-13 Trailer Tire and Wheel Fit in Place of a 5.30-12 Trailer Tire and Wheel
    If you want to go to the next size up from a 5.30-12 tire you will need to look at 13 inch wheels and tires ST175/80-13. For a wheel and tire combo with 5 on 4-1/2 bolt pattern and radial tire use # AM31985. This tire will be 7 inches wide and 24.1 inches tall and is rated for 1,610 pounds at 65 psi. The height and width of the new tire is important because you need to have the space all around the existing tires to go to a larger size. A 5.30-12 tire is 5.6 inches wide and 21.9 inches...

  • Recommended ST185/80D13 Bias Trailer Tire for a 2011 Jayco Pop Up
    Yes, you can but we also have a few sets of ST185/80 D13 that will fit your Jayco Pop Up. The Loadstar ST185/80D13 Bias Trailer Tire with 13" White Wheel - item # AM3S331 would be the best option. This is a Load Range D tire with a 1,660 lbs weight capacity. The rim has a 5 on 4-1/2 lug pattern.

  • Trailer Tire Recommendation to Replace Tire Size P155/80R13
    The tire size you have is for passenger vehicles since it starts with the letter P. You shouldn't run that style of tire on a trailer so replacing what you have is the right move. We have a very similar size as 175/80-13 that is rated for trailer use. For a wheel and tire you'd want the part # AM31985 for if you have a 5 on 4-1/2 inch bolt pattern or part # AM3S040 for if you have a 4 on 4 inch bolt pattern.

  • Difference Between a ST175/80D13 and a ST175/80R13 Trailer Tire
    The difference between the letter D in your ST175/80D13 and the R in the tire size of the Wheel and Tire ST175/80R13 part # AM31985 that you referenced is the tire construction. D stands for bias-ply which is a less preferred tire construction, whereas R stands for radial. Because of the construction of a radial tire, the tire has more flex and will allow for more ground contact. That will improve traction and better tread wear. It also gives the radial tire better stability. The radial...

  • Replacement Wheel/Tire for 2019 Scamp with Higher Weight Capacity
    Hey Eileen, I looked through your order notes and it looks like you got from us the part # AM31985 which is the size 175/80-13 on a 5 lug wheel. In that size we have a Load Range D with the part # AM3S333 which has a weight capacity of 1,725 lb per wheel/tire so it would get you more capacity than you'd need.

  • Radial Trailer Tire to Replace Bias Ply 4.80-12 Trailer Tires
    The closest radial tire size we offer to your 4.80-12 bias ply trailer tire would be the Karrier S-Trail ST145/R12 Radial Trailer Tire # AM10140. This tire will be about an inch taller and wider than what you currently have. You will need to make sure your trailer has enough clearance for this. I attached a couple FAQ articles on trailer tires for you to check out as well.

  • Recommended Spare Tire for Zieman Trailer for Personal Water Craft
    I was able to confirm your wheels are 13 inches on your Zieman J1-B trailer. Because I don't know the tires currently on your trailer, I can only make recommendations for your spare based on best options for the two bolt patterns. If you have a 5 bolt wheel, then I recommend the Karrier ST175/80R13 Radial Trailer Tire with 13" White Wheel # AM31985 If you have the 4 bolt wheel, then I recommend the Loadstar ST175/80D13 Bias Trailer Tire with 13" White Wheel # AM3S120.

  • Changing from a ST205/75D15 Tire and Wheel to a ST205/75D14 Tire and Wheel on a Trailer
    The main factors that you will want to take into consideration when moving from a st205/75d15 tire and wheel to a st205/75d14 tire and wheel is the weight capacity of the smaller tire and wheel and the bolt pattern. The weight capacity of a trailer tire is divided into load ranges, B, C, D, E, or F, however, tires with the same load range will have different weight capacities for different size wheels. For example, a load range C tire for a st205/75d15 tire and wheel will have a weight...

  • Selecting a New Axle, Wheels and Tires for a 4 x 8-Foot Utility Trailer
    An easy way to replace your axle is to use a complete kit such as Dexter # 20545I-EZ-60-15. This kit consists of the 60-inch axle, idler hubs, bearings, seals, lug nuts and grease caps - and even grease. This axle is rated for 2200-lbs and its spring centers are at 48-inches. Its hubs have the same 5-on-4-1/2-inch bolt pattern as the wheel/tire you referenced, part # AM31985 from Kenda. This kit will work with 13-inch wheels. Note that you will need to weld on new spring seats on top of...

  • Can 12 Inch Wheels And Tires Be Replaced With 15 Inch Wheels And Tires On Camper Trailer
    The main concern when you want to install bigger tires and wheels on your trailer. You will want to make sure you have the clearance needed for new tires and wheels. Going from 12 inch tires to a 15 inch is going to raise the trailer substantially. A typical 12 inch tire we offer has a range from about 20 to 22 inches diameter. If you put 15 inch tires on the trailer that diameter can range from 27 to about 28-1/2 inches. Increasing the tire and wheel size on your trailer will not increase...

  • Replacement Axle for 5 x 10 Utility Trailer
    Thank you for all the information; you seem to know the measurements you need, which are hub face to hub face and spring center to spring center. The closest axle we have to the measurements you gave is the Dexter # 20545I-ST-72-15, which measures 72" from hub face to hub face and 58" from spring center to spring center as shown in the accompanying photo.

  • Correct 13" Wheel to Install the Americana Baby Moon Trailer Wheel Center Cap
    The Americana Baby Moon Trailer Wheel Center Cap # AM90086 installs on wheels that have a raised inner ring that the center cap can snap to so it isn't compatible with the Karrier ST175/80R13 Radial Trailer Tire with 13" White Wheel # AM31985. For an alternative tire/wheel combo we have the Loadstar ST175/80D13 Bias Trailer Tire with 13" Black Wheel with +.5 Offset # AM31241 which does come with the raised center but it has a Bias tire and a wheel with an offset.

  • Can Larger Trailer Tires be Put on a Trailer with 4.80-12 Trailer Tires
    You can potentially use new tires and wheels on your trailer as long as there is clearance all around the existing tires for the larger size. Going to a 13 inch like with # AM31985 you will need at least 1.8 inches clearance above the existing tires and 2.095 inches at the back between the trailer and tire for the wider size. Trailer tire and wheel combo # AM31985 is a radial tire with steel wheel, 5 on 4-1/2 bolt pattern. It is a load range D rated for 1,610 pounds at 65 psi. Please note...

  • Recommended Upgrade for 205/65-10 Tires
    I do have an option for you but the only option we can offer to upgrade 205/65-10 tires would be to switch to a larger wheel/tire. For this, the best option we have for increased capacity is the Karrier ST175/80R13 Radial Trailer Tire with 13" White Wheel part # AM31985 which uses a five bolt wheel and has a 1,660 lb capacity. It will be about 3.5" larger in diameter and 1.4" smaller in width.

  • 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...

  • Larger Tire Size Recommendation to Replace 4.80-12 to Gain Ground Clearance
    If you go to a 5.30-12 inch tire size you'd gain 1.4 inches overall over your current size of 4.80-12. Also this tire size will fit the wheels you currently have as well. For that we have the Taskmaster part # TT53012C which would be a great option. It has a weight capacity of 1,050 lbs at 80 psi and a speed rating of 81 mph.

  • Trailer Wheel Pilot Hole is Close But Not Exact for Hub-Centric Idler Hubs and Wheel Bolts
    The difference between 2.8 inches and 2-7/8 inches is only 0.075 inches. That will work out fine for your hub-centric style hubs and wheel bolts. The other option is to replace the hubs with ones that use lug nuts. For that I would need to know the inner and outer bearing numbers stamped into the sides of the bearings in the hub you have now.

  • Best 13 Inch Trailer Tires and Wheels for a 1500 Pound Casita Trailer
    All wheels are not created equally! And the same goes for tires. The P in front of your tire size indicates that the tires are for passenger vehicles, not trailers. This is a problem because trailer tires and vehicle tires are constructed differently. Trailer tires are built with a thicker sidewall than passenger vehicle tires to handle more vertical load. You really need to switch to ST (special trailer) tires for your trailer. The wheel, since it came off of a trailer, will be fine for...

  • Can a Jet Ski Trailer go From 5.30-12 Tire to a 175/80-13
    The 5.30-12 tire size is 21.9 inches in diameter and has a section width of 5.6 inches. The 175/80-13 has a diameter of 24.1 inches and a section width of 7 inches. So basically as long as you have room between the frame and the inside of your current tire for 3.5 more inches, and have room for 1.5 more inches between the top of your current tire and the fender you should be good. For a 5 on 4-1/2 inch bolt pattern rim and tire you would want the part # AM31985, for a 4 on 4 inch bolt...

  • 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.

  • 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...

  • Should I Upgrade From a 12 inch Tire to a 13 inch Tire on a Rockwood Freedom 2290 Trailer
    I would recommend staying with the 12 inch 5.30-12 tire, like the Kenda K353 Trailer Tire, item # AM10068, for a couple of reasons. First, going with the larger, higher capacity tire will provide a stiffer ride for your trailer suspension and trailer. This will cause wear on the suspension parts. Next, going with a higher capacity larger wheel and tire than recommended by the manufacturer or axle capacity makes the trailer suspension the weakest link in the system. If a failure occurs...

  • How to Determine if a Trailer Wheel is Hub-Centric or Lug-Centric
    First, I would say if there is any question on the road worthiness of the trailer, take the steps to correct it. Better safe than sorry. Some trailers have wheels that are hub-centric, the wheel is centered on the hub using the center pilot holes. Other trailers have wheels that are lug-centric, the wheel is centered on when you tighten down the lug nuts. To determine which one you have on your trailer, take a look at how the wheel attaches to the hub. If it uses wheel bolts, like # 7-23,...
