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"

The mount and the tire are high quality and a good match for my 2018 Malone MPG525 trailer.


Everything worked out amazing. Little nervous about ordering cause I wasn't sure if I was ordering the right trailer tires I knew what my tire said and what I thought was the right trailer tire and rim. Their video on how to measure your trailer tire was awesome just to give me some good peace of mind. I went with three day shipping because I ordered my tires and rims on a Friday when I was leaving for the river on a Thursday and they got the order processed and shipped out. I went with three day shipping because I ordered my tires and rims on a Friday when I was leaving for the river on a Thursday and they got the order processed and shipped out. I got them on Wednesday it was amazing.


Exceeded my already high expectations. I live in rural Hawaii and my complete boat trailer axle down to tires was delivered within a week of order with reasonable shipping charges.. Local place gave me runaround 3x already. This saved me. Now I can go fishing again!

Dimensions and sizing can be difficult, even if you are used to these things but trailer makes it super ez.. With videos and detailed things. Thank you, I will definitely do business again!!!


Purchased three to replace boat trailer tires. They fit first try. Retina searing galvanized coating is thick and should hold up longer than the tires. Tires arrived with 70# psi air pressure and required minor topping up to spec's. No blemishes or bulges, thick grabby tread. See you on the boat ramp!


easy explanation, perfect fit, and fast shipping


I bought 3 (actually 4, read on) of these. One tire came off after the first few miles. I had checked psi at 87 directly before the maiden trip. These tires when filled to the max 90 psi seem to like to settle at 87psi. The tire came off shredded to pieces, I called customer service etrailer and they cited my "low psi" as the cause.
Etrailer stated it was impossible for there to be a defect, and begrudging said they would refund if I paid return shipping. I bought another tire, due to my need for a spare. I still have the other tire in the trailer box sitting in my garage. I don't care for etrailer's return policy and will likely discard of the tire when I clean the garage.
Etrailer sent me an email asking how the tire was doing after a year past purchase. I have to admit that made me laugh. I have spent thousands of dollars at etrailer, I haven't spent a dime since and never will again.


Super service, fast shipping, arrived in excellent condition - good packaging. Matched the listing. Have not yet tried them.


Arrived Quick! Nice tires!


Received the product extremely fast. Ordered/shipped on the same day and received two days later. Perfect fit on my boat trailer. After installation I topped off the air pressure and I'm ready to go. The lady's at etrailer are really nice

Tires are wearing well. I keep up proper tire inflation which is important with small wheels and tires. Very pleased with my purchase.

As advertised


Excellent price, combined with free shipping makes this the best deal I found by far. I recently bought a 3 year old boat and trailer with 4 ply tires (already showing some dry-rot) that were barely rated above total combined boat + trailer weight. I was just going to buy new 6 ply tires, but e-Trailer had the same tire mounted galvanized rims for just $4 more than the tire alone. I haven't been able to put any real millage on them yet, but so far I have to give these 5 stars.


I been looking for a wheel and tire all over with no luck. Found Etrailer online. The personal and service was awesome. They did everything they could to make sure I had the right wheel and tire. Thanks again everyone at Etrailer.


I truly appreciate the fantastic customer service. Look what arrived at 10:30am. I'm indeed grateful.


Bought two kendra tires and rims a year aa go .Just purchased another tire and rim for a spare. Good price ,shipping was fast . Very satisfied will continue buying from etrailer


Perfect product and delivery. Thank you so much!!


Had these rims and tires for a year now, and they are fantastic.


This trailer tire exceeded my expectations! This is a 6ply (rated to 925 lbs.) High speed trailer tire mounted on a heavily galvanized rim that is as good or better than the original wheels on my magic tilt boat trailer. I also purchased the Fulton High Rise tire carrier and wheel stud lock. This was an excellent addition to my trailer and highly recommend etrailer for fast service, excellent quality, and a great price. You will not find a better deal at any big box store.


For all my trailer needs I'll go to etr ailer.


I went to a local Tractor Supply to buy these first. Only had one and it was a painted steel wheel. I got the pair delivered to my door for $20.00 less and they were galvanized. Exactly what I needed for the salt water. Thanks


etrailer provided excellent product support and prompt shipping. The LED trailer light I ordered was installed when received and has worked flawlessly since purchased over a year ago. I highly recommend based on my experience.



I have nothing but good things to say about the people at etrailer. This was my 2nd or 3rd time purchasing from them and each time their agents on the phone are professional and courteous. They keep you updated with shipping information by e-mail, and I think their prices are the best. I was able to buy wheels for my wheelchair lift from them for less than half than what the "mobility vehicle store" in my area was going to charge. Thanks to Christina J this time for excellent customer service


Great product I purchased 3 tires and wheels for my boat trailer about a year ago. They handled good on the highway .And still look as new. Kendra AM30070


Decent economical tire wheel combo. Biggest concern in any trailer tire for me is sidewall rot from sun and minimal use. After one year, so far so good.


I was very pleased with the products
I bought from e trailer,, everything was perfect, the tracking was spot on, I thought the price
Was excellent. I would use e trailer again in the future.


Excellent service. Higher rated tire than I took off. Price with wheel cheaper than I could have new tire mounted on old wheel. Now I have two spares

  • Wheel and Tire Combo Recommendation for Size 4.80-8 with 5 Lug Wheel
    Realistically you need to pick the tire that has the needed capacity for your trailer. Going with one Load Range over the other won't give you a noticeable difference in bounciness but it is the best solution to go with a tire with at least enough capacity. To be safe a Load Range C like part # AM30070 would work best and it wouldn't cause any bounciness. I say it would work best because the capacity would for sure be enough and it has the needed bolt pattern of 5 on 4-1/2 inch.

  • What is Max Speed Rating of Kenda Trailer Wheel and Tire # AM30070

  • Recommended Replacement 4.80-8 Trailer Tires
    The best option to replace 4.80-8 tires would be to replace both the tire and wheel together as the pre-mounted options we offer will be more cost effective than buying the tire separately and paying to have it mounted. I recommend the Kenda 4.80/4.00-8 Bias Trailer Tire with 8" Galvanized Wheel - 5 on 4-1/2 - Load Range C Item # AM30070 for replacement.

  • Is Kenda 4.80 Bias Trailer Tire w 8 Galvanized Wheel-5 on 41/2 - LR C # AM30070 Directional
    We have the Kenda 4.80/4.00-8 Bias Trailer Tire with 8 Galvanized Wheel-5 on 41/2 - Load Range C # AM30070 that it sounds like you are looking for. This is not a directional tire which means you can install it on either side of the trailer.

  • Recommended PSI For 4.80/4.00-8 Tire Included In Wheel and Tire Combination AM30070
    The 4.80-4.00-8 tire included in the Kenda 4.80/4.00-8 Bias Trailer Tire with 8" Galvanized Wheel - 5 on 4-1/2 - Load Range C # AM30070 should be run at its max pressure of 90 PSI. Trailer tires are designed to use the max PSI with the exception of the Goodyear Endurance line, and not running the max pressure in a trailer tire can cause excessive heat which can lead to blow outs and other premature wear. I included a video of the # AM30070 for you to take a look at.

  • Low Profile Trailer Wheel and Tire with 5 on 4-1/2 inch Bolt Pattern for Snowmobile Trailer

  • Can I Go From a 4.80/4.00-8 Tire to a 4.80-12 Inch Tire and Wheel on my Boat Trailer
    You may be able to use the Kenda 4.80-12 Bias Trailer Tire with 12" Galvanized Wheel - 5 on 4-1/2 - Load Range B # AM30590 but this will depend on the amount of clearance you've currently got between the top of your 4.80/4.00-8 tires and the fenders or trailer frame. The # AM30950 will be about 5 inches larger in diameter than your current tires and you typically will need about 3 inches of clearance to avoid contacting the fenders or frame, so you'll want to make sure that the larger tires...

  • Spare Tire/Wheel Combo and Carrier Needed for 8 inch Wheel on Trailer
    We do have some tire/wheel combos that use an 8" diameter x 3-3/4" wide wheel with a 5-bolt pattern and for that I recommend the Kenda 4.80/4.00-8 Bias Tire # AM30070 which comes with a galvanized wheel that will do better to resist rust and corrosion. This tire is a larger Load Range C which means it can handle 760 lbs at 90 psi. You just need to make sure that this tire size and load range match what you currently have otherwise your trailer will eventually develop a poor ride quality...

  • Replacement Leaf Springs and Tire for 13ft Rocket International Supreme Boat Trailer
    Thank you for all of that information; it definitely makes it easier to identify the appropriate parts, and it looks like you were on the right track. If your boat and trailer weigh less than 1000-lbs total, the UFP Slipper Spring for 1000-lbs Axles # SP-177275 is 24-5/8" long and will fit perfectly in the 23-1/2" center eye to slipper spring bolt hanger that you mentioned. If you think the boat and trailer combined weighs a bit over 1000-lbs, the # SP-178275 are a 1500-lbs spring with...

  • Replacement 4.80/4.00-8 Tire & Wheel Combination

Each wheel will have a maximum load capacity of 745 lbs at 90 psi. This tire will have a diameter of 16.1 inches and a width of 4.7 inches. If you have the 4 on 4 inch bolt pattern, I recommend the powder coated # AM30040 or galvanized # AM30050.

  • Fit and Compatibility of 4.80/4.00-8 Trailer Tire on Waverunner Trailer Equipped with 5.70-8 Tires
    It sounds like your waverunner trailer has the 5.70-8 trailer tire on it. The smaller 4.80/4.00-8 Bias Tires # AM30070 you referenced would fit your 5 on 4-1/2 inch bolt pattern but may not be compatible with the weight rating of your trailer and waverunner. The Load Range C # AM30070 has a capacity of 760lbs at 90psi for a total axle weight of 1,520lbs. If your trailer and waverunner are within these limits then this combination could work for you.

  • Recommended Trailer Tire with Higher Speed Rating for Size 4.80-8
    I have a great solution for your tire size that has a higher speed rating of 81 mph. We only have them with wheels with the part # AS4808B4WS with a 5 on 4-1/2 bolt pattern. The only way you'll be able to safely recommend you do 70 mph with this option for your trailer. For the 5 on 5 bolt pattern we have the replacement tire and wheel with the part # AM30070. But even though the description says that these work great at the highway speeds, my research shows that the limit is 65 mph.

  • Replacing Tires for Boat Trailer With Low Ground Clearance
    My best recommendation as a replacement tire is Kenda 4.80/4.00-8 Bias Trailer Tire with 8" Galvanized Wheel - 5 on 4-1/2 # AM30070. I cannot recommend going up a full tire size since the ideal fender clearance is about 3 to 4 inches and the next size will add at least 4 inches to your current diameter. Also, please check if the bolt pattern matches. I linked our article on bolt pattern measurements below. If you're worried about clearance, have you thought about lifting it? We offer kit...
