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"

Great price, quick shipping and exactly as ordered. I will recommend etrailer to others and will purchase from again when needed in the future. 264902

- AM31206HWTB

I am very happy with the quality and look of my new tires and rims. Although there were some problems with receiving the correct rim, which had to be shipped back. The new rim and tire was shipped very quickly and I received it in less than a week. I have purchased other product from Etrailer and haven't had any problems. I would certainly recommend Etrailer and would go back to them when needed 247847

Looks good and rides good. The tire arrived in a timely manor. Also the tires were stamped 2017. 446748

This was a great upgrade. Good investment to breath new life back into your trailer. Original tire was a 4.80-12. These fit perfectly without any modification to trailer or fenders. 869613

I ordered radials over bias ply for my motorcycle camper trailer off of a recommendation from an etrailer post and was not disappointed. I just got back from a long weekend and the trailer pulled excellent. The mag rims really set off my trailer also. 831440

- AM31206HWTB

Fantastic upgrade. More width and mildly increased diameter than the factory original wheels/tires. The black accent really stands out and looks great, especially coupled with the chrome wheel covers with the black cap! Shipping was quick and easy as was instillation. 828305

Tires and wheels I ordered came in perfect. Everything I have got from Etrailer has been perfect. If only other online vendors would be this consistent life would be wonderful!!! 818638

Product came sooner than originally thought even with the back order. Great looking set of wheels and tires. Looking forward to putting them on my trailer and testing them out. I was very impressed with the service at etrailer and the phone call to let me know the items were backordered and provided alternative options if I didn't want to wait. Great company and great products! 804498

Shipping was very fast, tires and wheels were packed perfectly, and the wheels are amazing. Outstanding product and customer service! 639562

- AM31206HWTB

Great wheels and tires. A Huge improvement over the original bias ply tires. My Coleman Pop-Up tracks better and doesn't bounce as much on rough roads. I was going to just buy tires but the cost of mount/balance/disposal was about the same with no hassle. I had the extra time to clean and repack my bearings too. The new grease caps also fit just fine. 612294

- AM31206HWTB

Top of the line wheels and tires for a top of the line Waverunner. VERY nice tires and wheels. The tires are WAY beefier than the stock ones. Adds a lot of bling to the whole rig. I ended up putting 1/2 ×20 chrome lug nuts on. These are 3/4 drive which gives plenty of clearance around the nut and enough length to easily get a lug wrench on them. I will feel way safer at highway speeds than with the stock tires. 603260

- AM31206HWTB

It was exactly what I ordered good quality product and fast delivery very satisfied!! 601588

- AM31206HWTB

  • Weight Capacity Difference Between ST145/R12 Load Range D and Load Range E Tires
    We don't sell a load range E tire mounted to that particular wheel, but the wheel and the tire are available separately. The ST145/R12 Load Range E tire is part # AM10140. The 12" Aluminum HWT S5 Black Wheel with 5 lug on 4-1/2 inch bolt circle is part # AM22319HWTB. We do not have the equipment to mount the tire on the wheel, but you could have that done locally.

    I can help you determine if the Kenda ST145R12 Radial Trailer Tire with 12" Aluminum HWT S5 Black Wheel # AM31206HWTB will fit, though we would not have any way of knowing that off hand. Determining this is pretty easy though, you just need to know that you have the same bolt pattern, and that you have the right amount of clearance. Let's start with bolt pattern; this wheel has a 5 on 4-1/2" bolt pattern, and to determine if it will fit you will need to use the linked help article on...

  • Speed Rating on Kenda Radial Trailer Tire Size 145/80-12
    The Kenda radial tires like what comes on the part # AM31206HWTB that you referenced have a speed rating of 65 mph. In this tire size this is the highest speed rating we offer. We can never recommend lowering the psi of a trailer tire as that lowers the capacity and allows heat to build up in the tire due to the additional flex as it travels down the road.

  • How to Determine if 145R12 Trailer Tire with 5 on 4-1/2 Bolt Pattern Fits Harbor Freight Trailer

    The Kenda ST145R12 Radial Trailer Tire w/12" Aluminum HWT S5 Black Wheel - 5 on 4-1/2 - LR D # AM31206HWTB you asked this question from are great tires for travel on roads and highways. Trailer tires are built for stiff sidewall and to be run at the max psi which makes crossing sand anything but ideal. The best option is to get a second set of tires with a low load capacity rating like # AM30750 so the sidewall isn't as strong and then let the psi of your tire run as low as possible...

    The trailer tire size ST145/R12 is a very stable size that would work well on your snowmobile trailer.

This has a capacity of 1,220 lbs at 65 psi which would be more than enough.

  • Best Wheels for 2003 Rockwood Freedom Pop-Up and 145R12 Tires
    Based on my research your 2003 Rockwood Freedom pop-up camper will have wheels that are 5 on 4-1/2 inches. Your 145R12 tires will fit any 12x4 inch rim, so I've attached the link to all your options. For a traditional option, I recommend the Taskmaster Steel 8-Spoke Trailer Wheel # TTW240545WS1 which will give you the factory original look.

So what it's going to come down to between these two options is the wheel that they're mounted on. The Kenda Karrier S-Trail # AM31199DX are going to be a more basic, white spoke wheel which is just going to give basic rust protection. The # AM31206 are an aluminum wheel that is going...

Instead you will need to purchase the wheel and tire separately and take them to your local tire shop to have them mounted and balanced. The correct tire you will want to use is the Kenda Karrier S-Trail part # AM10130 for load range D or part # AM10140 for load range E. You will also need a valve stem and for that I recommend part # AM20907. The correct center cap for the above...

    You would need to go with a trailer tire that has ST before the size as they are the only tires rated for use on a trailer. You would need to go down to a 12 inch tire and wheel so that you can go with something that will fit your trailer. For that you would want the part # AM31208 for if you have a 4 lug bolt pattern or part # AM31206HWTB for if you have a 5. These wheels overall diameter will be just a tiny bit smaller than the size you currently have that does fit.
