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"

Bias tire has a ply rating of 6 and a 990-lb maximum load at 90 psi. The 12" diameter x 4" wide steel trailer wheel features a 4 on 4 bolt pattern and a corrosion-resistant galvanized finish.


I was trailering a 650+ pound boat and motor on little 8 inch tires and knew I was on borrowed time before a highway blowout. These upped my load capacity from 575 to 990 pounds. Ordered two sets of rims/tires as replacements plus a spare. They came well-boxed.Manufacturing date was about 10 months ago. Changed them in my driveway with a small floor jack placed under the axle right under the leaf springs in less than an hour, with the boat on the trailer. As others mentioned, the galvanizing is thorough but rough in spots. Be sure to check tire pressure before installing;mine arrived with very little air in them. Quick shipping. A good value. I'm happy. Recommended.


This is my iceboat trailer with new wheels and improved fender brackets. Rust prevention is my main goal on this order. The price was lower than the local store. The delivery was completed in under 48 hours. Amazing! I believe the former white painted wheels were purchased about 10 years ago. They need restoration. The tires might have 2000 miles on them. I recommend galvanized wheels as in this new order. Two wheel and tires for under $100!! Fantastic – and much cheaper than the local tire dealer who offers white painted wheels that rust - by over $20. And free shippng.

By the way, each fender now has two brackets as suggested by eTrailer.



The trailer sat in the woods all summer,since it is a iceboat trailer used in winter. I just pulled it home from the cabin. The wheels look perfect. They have a silver finish, not white paint. Happy!


These galvanized wheels were perfect for my utility trailer. Great price, delivered fast, installed easily and make the trailer look new.
I'd highly recommend the galvanized type over the white painted style.


My tire needs came up rather quickly and I needed an affordable solution, pronto. I found a variety of tires/wheels and prices that fit my needs. I also found useful advice in choosing the right tires for the job and I highly recommend using it. It's too soon to tell how long the tires will last but, I was very satisfied with the selection, prices, fast delivery and ease of use.



After several trailer loads, my tires and wheels still function like new. I wanted to fix it and forget it. Done! Recommended.


My whole experience from start to finish couldn't have gone any smoother. i called eTrailer with alot of questions. I needed to go from an 8 inch tire to a 12" tire,they were nice,knowledgeable and pateint. i found the tires and the wheels i wanted and had them within two days of ordering. just put them on my boat trailer and they look great!



its been over a year since i got these tires. After many trips and many miles they are still working great. Would and will definitely buy these again.

Horrible Quality! Rim had many manufacturer defects and was bent and out of balance since day one. The tire was properly inflated and had a blowout after only a few hundred miles. Quality control is lacking. Spend your money on a quality rim and tire. This isn't one!


Great tire/wheel combo. Fit perfectly. Came inflated to around 50 PSI, so was ready to use once installed. Delivery was very clean. Both wheels packed in a long, narrow box. Easy to handle. Would buy this again.


Great quality at a fair price! Worked great on our little utility trailer.


The tires look good but the wheels have a few rough welds that appear to be where the wheel seams...ugly. The edge of the wheels also are iregular shaped at certain points. I do hope the wheels hold up without cracking at the seams.


I chose to purchase my trailer tires and wheels from e-trailer because I consider them the leader in the field. I shopped hard, and the price was good. When my galvanized 4-lug, 6-ply, 12" wheels arrived they were even better than I hoped.


Very happy with the 2 4.80X12 tires and wheels from Ordered on a Saturday and delivered to my door on Wednesday. Fast shipping and quality products at a great price! For use on a used boat trailer I picked up to haul my fishing kayak. Will order from this seller again!


They fit good and look good on the trailer. A lot safer than the tire that I took off.


The tire I had originally picked on etrailer for my motorcycle trailer was out of stock but I needed them for a motorcycle trip I was leaving for that same week. An etrailer staff person (James) notified me immediately and helped me find a equal replacement that arrived on time at no extra cost. I am very pleased with the tires he recommended. They performed exceptionally well on my trip.

Great product and even greater service!

Ed S.


Still very happy with my trailer tires! Great product and I have had zero issues with them.


Great service, shipping and rfect!


Ordered a pair of Kenda 4.80-12 trailer tires and galvanized rims, Item AM30630. Excellent quality products, well packaged and delivered promptly. Got 'em today, very satisfied, and they make my little firewood trailer look like a million bucks.


Happy with this purchase and the customer support received. When I first ordered I didn't realize there was a galvanized wheel, nor that there was a tire with a higher load capacity in the size I needed. etrailer sent me a shipping label to return the first tire, and I wound up getting two. One year later, no rust on the rims, tires have been performing well on my canoe trailer, and holding their air well. Stored outside, my only concern is that weather will 'retire' them before mileage does which is typical of any trailer tire I think.


Very nice rim and tires, great and fast delivery, only negative issue is rims are galvanized and finish is not appealing, had I know I would of saved money and bought white for $XX less now it will cost me to have them powder coated

Yes, these wheels are dipped in a galvanized solution and allowed to drip dry which can make for a rough finish. This is typical with galvanized wheels from this manufacturer.


I don't use the trailer as much but when I do I usually overload it not really knowing the wait of the load mostly fresh wood chips. But the tires, they have been holding up and not splitting in half!


I give it five stars for availability of products. This is the second time trailer has been able to provide a product I needed in a timely manner. I did buy the lessor expensive item of choice instead of the better item so I’m not complaining, but the finish on the galvanized wheels is a little rough. Hopefully it will hold up a while and not quickly rust.



Finish is still holding up well on my wheels and the tires are still going strong.


Bought to tires and this wheel and tire as a spare. My 2 tires of the same model are fine on my lightweight trailer. The wheel looks good although I have never run it on the road. I would buy it again if I needed one.


Put these on my boat trailer as the original ones were dry rotted. Wheels look better than the painted ones. Tires are good quality.No more tire worries!


Got a set of these for my single place PWC trailer. I converted it to a 2 place stand up trailer and replaced the wheels/tires along with most everything else. These wheels look great and ride nicely.
Tip: Use one of your old wheels/tire as a spare. Order a spare tire holder from etrailer.


One year later and a thousand miles, and these rims and tires have held up excellent. No rust on the rims and the tires are wearing evenly.


Product fits like a glove and Emily W she is awesome


Galvanized wheels in New York are a must. This wheel and tire combination is working well for me.

  • Can 4.8-12 Tire Size Fit on Wheel that Had 4.8-8 Tire
    The numbers at the end of the two trailer tire sizes you mentioned are the wheel size they are intended to fit so what you are wanting to do is not possible. The size 4.8-12 is for a 12 inch wheel and the 4.8-8 is for an 8 inch wheel. So to go to the 4.8-12 size you'd need a wheel and tire combo like the part # AM30670 for if you have a 5 lug bolt pattern or # AM30630 for if you have a 4 lug bolt pattern.

  • Solution for Fitting Modern Trailer Wheel and Tire Size to Boat Trailer Axle with Old Spindles
    The easiest solution will most likely be to cut off the spindles and install a set that have dimensions compatible with current trailer hub/drums which will allow you to use a standard wheel. To use the hub part # AKIHUB-440-2-1K that you referenced you'd need a BT8 spindle like the part # TRU94FR. From there you could install a standard wheel with a 4 on 4 inch bolt pattern like the Kenda Wheel and Tire part # AM30630 which is a 4.80-12 trailer tire mounted on a 12 inch wheel.

This will give you an idler hub and suspension to give the log splitter a smoother ride on the roads. The hubs will accept a 4 on 4" wheel and tire like the # AM30630. Otherwise you can get 2 Spindles # TRU44FR to weld onto your trailer in place of the wheelbarrow type axle. Then you will be able to add 2 Hubs # AKIHUB-440-2-G-EZ-2K which also...

  • Which Trailer Tire Size is best for a Jet Ski Trailer that has 4.80-12 Tires
    Increasing tire width will not really benefit you in any significant way. You would see a slight increase in stability, but if the trailer already rides pretty straight, you may not see any improvement. The 5.30-12 tires would also make the trailer sit a bit higher. My suggestion would be to use part # AM30630. It is a galvanized wheel for 4 on 4 pattern. It is a load range C bias ply tire and each wheel would be capable of supporting 990 pounds at 90 psi, which should be more than enough...

  • Maximum Air Pressure Rating on Kenda 4.80-12 Trailer Tires # AM30630
    The maximum air pressure for the Kenda 4.80 -12 Bias Tire and Galvanized Wheel Combo # AM30630 is 90psi, so that should be what you run them on. Trailer tires should always be inflated to the max air pressure rated for the tire because they have a thicker sidewall than normal passenger tires and are built to carry more vertical load that occurs with a weighted down trailer. The tires should also be inflated to 90psi when cold, meaning before your trip. I attached a helpful article from...

  • How to Compensate for Trailer Coupler Much Shorter Than Tow Vehicle's Receiver
    It sounds like you're trying to make sure that your trailer is towed level, which is always important for safety. However, by the looks of that trailer, the fenders you've got on there are going to really limit the size tire you can put on there. You normally want to leave at least 3" between the top of the tire and the fender so that you don't damage the tires when going over any bumps or anything, so I'm not sure that adding a larger tire is going to be the best solution.

  • Determining Correct Bolt Pattern and Tire Size for Replacement Tires and Wheels on Jayco Camper
    To determine the bolt pattern on your existing wheels, you will measure center-to-center on lugs directly across from each other (not next to each other).

I have attached a very helpful article that explains exactly how to do this in more detail for you to check out. You will then want to locate the tire size on your existing Jayco J-Series tires.

  • Do I Need to Give My Kenda 4.80-12 Trailer Tires # AM30630 Time to Cool Down When Driving
    The 90psi is going to be the cold filling pressure; as you drive, the tires are going to heat up and the air inside them is going to expand. When running long distances, most tire manufacturers recommend that you stop for 30 minutes for every 3 hours of driving in order to let the tires cool down. After each stop, it would be a good idea to check your tire pressure and make sure that they're not going below the 90psi if you are having tire pressure concerns.

  • Recommended Tire & Wheel Replacement For 155x12 Wheel & Tire
    A 155x12 wheel and tire is not a very common size for trailers. A close match is going to be something like a 145/80-12 or a 4.80-12 like you mentioned. A 155 is going to be about 6.1 inches wide. A 145 will be 5.7 inches and a 4.80 will be 4.9 inches wide. The overall diameter of a 155 tire depends on the aspect ratio, the second number in the size, so a 145/80-12 tire has an aspect ratio of 80 percent. This means the overall tire diameter is 21.3 inches. Similarly, the 4.8 has a...

  • Are Radial Tires Better for Jet Ski Trailer
    Radials are the way to go for trailer tires that will be on the highway for extended periods of time. They just do everything better.
