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"

Excellent wheels and tires. Much nicer than the ones that came with my trailer. As always, great service from etrailer.com!



by:

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.



by:

If you go to TSC and buy some generic 12 inch trailer wheels and tires instead of these your mama should slap you silly. BEST PURCHASE EVER for your kayak trailer. And honestly, the customer service here is top notch. They followup on every purchase and the shipping is ULTRA fast! Top notch outfit, wish I could invest in them to be 100% honest! I have made numerous purchases, wheels, tires and spare for two trailers, towing hitches, wiring kits, and numerous other items



by:

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



by:

The wheel/tire combo is exactly what I was looking for. Just lifted my PuP 5.5" with an axle under/bigger wheels. Increased from 2 leafs to 4 to increase weight capacity for internal gear storage. Wanted a D rated tire for better on road piece of mind and to enable better boondock access. Solid product, and they look extremely rugged as well. A+

All on all, a good purchase that improves both function and looks.

Great product, looks great

great tires, working out well!

I needed a somewhat specialized tire, a 12" radial for a trailer. These guys were very knowledgeable with fair pricing and great fast shipping. I will use them again and recommend them to anyone in need of tires and or wheels.

Ask the Experts about this Kenda Trailer Tires and Wheels



  • 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
    To answer your first question, radial tires are superior to bias tires because they run cooler and are less prone to blowouts. The only reason to run a bias tire is if you do a lot of agricultural or off-road work.

  • Recommended Replacement Wheel/Tire For Existing 4.80-12 Tires on Boat Trailer
    The 145/80-12 tires would be about an inch wider and an inch taller than your current 4.80-12 tires. The 1 inch height difference would raise your ride height by a half inch, and the wider tread would provide more pavement contact for greater stability. Generally speaking, you'll want to see at least 2 inches of inside clearance between the tires inner sidewall and any portion of the trailer. If a 1 inch wider tire (which would move the sidewall 1/2 inch closer to the trailer frame) and...

  • Do Aluminum Trailer Wheels Require Special Lug Nuts
    Aluminum wheels actually have steel inserts where the lug nuts touch them so there is no need for an adapter and you can just bolt the wheel right up. I don't know what size wheel you are looking for but I attached a link to all the aluminum wheels we carry.

  • Can I Upgrade My Trailer Wheels From 8 Inch To 12 Inch?
    There are a couple factors that play a part in if you are able to swap your tires from 8 inches to 12 inch. If you're running an 8 inch wheel odds are that you have a single axle trailer so that shouldn't be an issue. If you have fenders on your trailer you may need to remove them. If that isn't a problem then you have two bolt pattern options. 5 on 4-1/2 or 4 on 4. Both bolt pattern options will have an overall diameter of 21.3 inches so you can use that to see how much height you will...
