Bias Tires vs. Radial Tires

Bias vs. radial tire graphic

Bias ply tires are designed for off-road or agricultural applications. They are built with thick, durable nylon cords that are positioned at a 30- to 45-degree angle to the direction of travel. The layers alternate in a crisscross pattern, making the sidewalls stiffer so that the entire tire is able to flex easily. As a result, the tire provides a smooth ride and improved handling when trailering on uneven surfaces.

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"

You guys are great.


No complaints. They work as expected rolling down the highway. I don't understand why trailer tires don't last as long as regular vehicle tires but it is what it is. As always, buying from etrailer is easy - thanks guys!


I am a Taylor Dunn cart restorer and I only use Kenda tire and wheel combination 570 X 8 and use new tires on my restoration. I had a few question and I received information and on the phone and the next day I received an answer to a additional question. On the tire and wheel combo you will not find a better price and service then with this company. I don’t work for them as you can see my cart restoration picture. Thanks for the great service.


Great service and products. Delivery was quicker than expected and easy to track. Won't hesitate to order again. Thanks.


I needed replacement tires for a small used quad trailer I purchased. These tires and wheels were perfect both in price and performance! I will definitely purchase them again when needed.


I could not be more happy with my recent purchase of two 8 inch wheels and tires from etrailer. The product replaced two worn-out tires, I made a move up in tire size from 4.80-8 to 570-8, now I feel better about the size of load I haul on my trailer.

I am satisfied I will get a lot of long term use from these tires.


I am still a happy customer.

Glad to review this item. I had just picked up a 1992 JetSki for my grand kids to use on vacation. It was a rust bucket trailer but the JetSki needed to be cleaned up. I replaced just about everything on the trailer it did not have a spare tire nor a place to put it. I had been looking at the etrailer web site and found everything I needed to make the trailer safe, so with everything I needed was there and the perfect spare tire and mounting bracket. I am almost ready to hit the road.


Put this wheel on a Coleman Popup Camper. It is round and black, like I like my tires.


Bought these replacement tires for small Coleman pop-up camper. Have them a year, they weathered great through frigid winter even though I left camper on ground instead of lifting on blocks. To be fair I only take it out once a year, so only a few hundred miles on them. BUT, I had trouble finding these in stock elsewhere and Crystal @ etrailer provided superb customer service in helping me find products I needed.

Still in great condition

I order my tires in the store at 3:30 pm. The next day about 11:00 am they were delivered to my home.


Great service and fast shipping


Great deal


So convenient! Thank you!!


Great experience from ordering to fast receipt of order, everything as described.


I ordered 2 trailer tires with rims on May 16th and they arrived on May 20th. My order was just as I requested, the tires were high quality and the price was comparable or less than what I would have paid locally, but the size I needed wasn’t available at any local dealer.
I am very pleased with my purchase from e-Trailer and I recommend them highly to anyone based on product inventory, quality, price and speed of shipping. . Also, their customer service department is very helpful and knowledgeable.

After a year, I am still very satisfied with the trailer tires I purchased. Great quality, great price.

This wheel is to be used as a spare for a dual hitch swivel wheel trailer. The swivel wheel uses dual tires. This is exactly what I needed as a spare. Quick response and shipping from


I bought a pop up camper from a private seller, and the tires and rims were mismatched and in poor shape, not safe for extended travel. These fit perfectly, in part due to the helpful fit information supplied on the product page, of how to determine lug spacing, etc. The quality and pricing of the product are outstanding. Thanks etrailer, you have a customer for life.


For reasons having no reflection on e-trailers or the tire/wheels, I was unable to use the tires for the project I purchased them for. However, they arrived quickly, the quality for the price appeared to be unbeatable, and the return process was painless.


excellent service !


Perfect. great quality for the price. rapid shipping, I'm very pleased, plus it makes my tractor look good!


I love the tires. I replaced "no-flat" rubber filled tires and they went flat on our school athletic golf cart. I have been riding on these new tires and it is a huge difference. The only issue is that the tread is so new that the wheel wants to move on it's own at times (but I do not see that as a bad thing since they have tread).


Etrailer is awesome! Excellent selection of products. Great prices! The review of products and explanations set a standard of excellence that e companies should aspire to.


Tires are just as expected. Shipping and customer service were top notch. Received a confirmation email with tracking info that was easy to use, and even received a delivery confirmation which was unexpected and appreciated. 10/10 would use them again. Keep up the good work!


I needed two tires for my boat trailer. I checked several of the local national stores, the correct size was unavailable. I turned to the Internet and searched the usual suspects and with eTrailer and there site was head and shoulders exactly what I needed. Placed my order and it was like a team went to work and within 3/5 days they were delivered to my front do!! Thanks for your service I would highly recommend etrailer for any trailer tire you may need. Fast Professional service.


I have owned these tires for a year. We've hauled things between Missouri and Tennessee. These tires have worked perfectly and are still in wonderful condition! We will order from this company again when we need new tires.

Ask the Experts about this Kenda Trailer Tires and Wheels

  • Can a 205/65-10 Trailer Tire Fit in Place of a 5.70 x 8 Trailer Tire on a Popup Camper
    Provided that the manual for the camper and the camper itself match, that is unique problem. I am inclined to lean towards the sticker on the trailer in this case. But, to be sure, you will need to determine the axle capacity and choose the tires and load rating that match it. The modern size for 20.5 x 8-10 is 205/65-10. This tire has a 20.5 inch diameter and it is about 8 inches wide. A 5.70 x 8 tire is 18.1 inches in diameter and is 5.7 inches wide so there is significant size difference....

  • Tire Pressure for Kenda 5.70-8 Bias Trailer Tire Load Range C
    Trailer tires should always be inflated to the maximum psi indicated on the tire. This is because trailer tires are built with a thicker sidewall to handle more vertical load. If the tire is under inflated that thicker sidewall will cause excessive heat build up and lead to tire failure. If the trailer does bounce around a lot then the solution would be to weigh down the trailer more (up to but not exceeding the trailer capacity). The Load Range C tires you now have are rated for 910 pounds...

  • Troubleshooting Motorcycle Trailer that Vibrates at High Speeds
    The thing about trailer tires is that unless otherwise noted they cannot exceed 65 miles per hour. It sounds like you exceed this speed and that is why you are getting vibration. Exceeding the speed rating will cause heat to build up in the tire and can cause premature failure. If you took your 8 inch wheels to a wheel and tire shop they should be able to balance them. Going to a larger tire might help you reduce some vibration, but I believe your problem is directly related to the speeds...

  • Weight Capacity of the Kenda 5.70-8 Bias Trailer Tire with Rim # AM30140
    The Kenda 5.70-8 Bias Trailer Tire with Rim # AM30140 that you referenced has a capacity of 910 lbs at 75 psi. Trailer tires should always be inflated to their max psi. If a trailer tire is inflated to a lower air pressure than the maximum, the amount of weight that the tire can carry will be reduced. If a heavier load is put on the trailer tire than what is recommended for that air pressure, the sidewall of the tire could heat up and cause the tire to fail.

  • Are Kenda Tire and Wheel Combinations Balanced?
    The Kenda Bias Trailer Tire # AM30140 you were looking at will come mounted, but not balanced like a typical car tire because it isn't necessary, they will be ready for use straight out of the box after receiving them. The Kenda tire and wheel combos we carry are not machined balanced. You can have the tire and wheel combos balanced at a local tire shop if you wanted to. What manufacturers will do is line up the light spot on the tire with the heavy spot on the wheel. This is a type...

  • Recommendation to Replace 5.70-8 Tires on Coleman Camper
    When inflated to its maximum psi a 5.70-8 size trailer tire like the Kenda # AM30140 that you are looking at should have an overall diameter of right around 18 inches. I'm not sure how much smaller a diameter you are measuring on your existing tires, but the difference might simply be caused by your tire being a bit under-inflated. Based on the picture you attached it looks like your current tire has a maximum psi of 50. Minor manufacturer variances might also contribute to a slightly different...

  • Will the Kenda 5.70-8 Bias Trailer Tire with 8" White Wheel Work In Place of a 9" Wheel
    The Kenda 5.70-8 Bias Trailer Tire with 8" White Wheel - 5 on 4-1/2 part # AM30140 that you were looking at would work just fine on a trailer in place of what you said was a 9" wheel. So long as the bolt pattern is the same you won't have any issues. That said, most likely the wheel you have on the trailer now is 8" as when you measure, it's not from end to end since you must exclude the lip which is about 1/2" on each side.

  • Recommended 5.70-8 Tire and Wheel Combo for a Popup Camper
    For your popup camper with 5.70-8 tires, I recommend choosing a bias ply tire with a load range of C or greater. A load range C rating will give you 1,820 lbs for two tires which will be plenty for your needs. For just the tire, I recommend using the Kenda K353 Bias Trailer Tire part # AM10012 which has a load range C ratings, 65 mph limit, and comes with a 2-year warranty. Some things you will want to avoid are overloading you trailer and exceeding the maximum mph rating as these will...

  • Trailer Wheel and Tire Recommendation for 1984 Jayco J Series Camper
    Most likely you have the need for the tire size of 5.70-8 since the wheels are 8 inch in diameter and 4 inch wide. So if that's the case we have two options. The part # AM30120 for if you have a 4 lug bolt pattern or the part # AM30140 for if you have a 5 lug bolt pattern. Verify the tire size though by checking what is printed on the sidewall of the trailer tire.

  • Comparing 5.70-8 Tires to 4.80-8 Tires
    The 4.80/4.00-8 tires # AM30020 are 4.6 inches wide with the outer diameter (when inflated) being 16.1 inches. They have a load capacity of 590 lbs at 60 psi. If you move to the larger tire # AM30140 you will have a tire width of 5.9 inches and an outer diameter of 18 inches. This gives you a little over 1 inch more tread on each tire and also gives you almost 1 inch more ground clearance. It will increase your load capacity to 910 lbs at 75 psi. These tires will wear a little better...

  • Recommended Replacement Tire for 5 x 8 Utility Trailer
    The # AM30140 wheel/tire combo you'd looked at would work well, assuming your existing wheels have a 5 on 4-1/2 inch bolt pattern. The tires are rated up to 65 mph, so they'd be safe at reasonable highway speeds. If you wish, you could go up in size to a 4.80-12 tire/wheel like # AM30660 which would move your tire 1 inch closer to the fender. You'll want to make sure you have at least 3 inches of clearance between the top of the tire and the underside of the fender when the trailer is loaded...

  • Recommended 5.70-8 Wheel/Tire Combo with 5 Lug Pattern
    I have some great wheel and 5.70-8 tire options for you to choose from. It's very likely you have 5 on 4-1/2" pattern which measures 4-1/2" from bolt center to bolt center. There is no bolt pattern for a wheel this size which measures 4-1/4" and 5 on 4-1/2" is most common therefore very likely what you have. It's hard to measure the exact center of a hole.

This combo contains a 5.70-8 bias ply, load range C, trailer tire with 910 lb maximum load capacity at 75 psi and a 8" white powder coated steel wheel which resists rust and corrosion. The 5.70-8 tire has a section width of 5.9" and has an outer diameter of 18" when inflated. I do recommend taking a couple quick measurements on your trailer to ensure that you have sufficient clearance for this tire.

    The dry weight of your 1993 Coleman Cedar Pop-Up camper is right at 1,000 lbs. You then have to add anything you've loaded into it to that number. Divide that in half and each tire should have a weight rating that is above that. The Kenda 5.70-8 Bias Trailer Tire with 8" White Wheel Load Range B part # AM30100 for instance offers a 715 lb. per tire load limit for a total of 1430 lbs. capacity.

Instead I recommend using the Kenda 5.70-8 Bias Trailer Tire with 8" White Wheel # AM30140 which uses a 3-3/4" wide wheel but has the 5 on 4-1/2" bolt pattern and a Load Range C (910 lbs at 75 psi) which is more than enough for your weight rating.

    I believe your tires use the old Inch size rating that was used in the 1960s and 1970s. I believe it is an 8.55-14. You will need to measure your tire to be sure. The 14 would indicate that the tires are on 14 inch wheels. The width should be about 8-1/2 inches wide. The closest modern tire is going to be a 215/75-14 like # AM1ST90.

  • Which Load Range 5.70-8 Tire for 1500lb Pop-Up Camper
    A 5.70-8 load range B tire has a capacity of 715 lbs, which is 1430 lbs per pair. If the weight of the trailer exceeds that amount, then you'd want to go with the load range C, with a 910 lb capacity (1820 per pair). Even if the weight of your trailer doesn't exceed the capacity of the load range B, I'd recommend going with the higher load range. If you just need the tire, go with part # AM10012.
