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"

Average Customer Rating:  4.8 out of 5 stars   (6137 Customer Reviews)

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.


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.


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!


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.


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.


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.


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 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.


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!


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!


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.


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.


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.


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


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.

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!


Product fits like a glove and Emily W she is awesome


Outstanding customer support and great product. I ordered Thursday evening and had them by Saturday afternoon. I tell all my friends that this is the place to go for trailer items.


Most polite and quick service and great product! Will keep ya'll in mind for my next purchases


Quality wheels and tire.


Easy ordering from an excellent website that clearly describes the items.


Great price for a galvanized wheel and tire package. Doesn't pay to put a new tire on a rusted steel wheel.


First, I would like to say "thank you" to Brandon and the rest of the folks for being awesome during my trailer restoration project. Accurate and courteous advice, fast service and just true genuine concern for the success of my project. The wheel/tire combination is great...but just the tip of the iceberg on top knotch service.


Just what I ordered. Arrived fast and in good shape.


Arrived promptly and in good condition. Price included free shipping and tire age @<5 months. Huge upgrade from 4.80x8 trailer tires. Pleased with the purchase process

  • 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...

  • What Tire Pressure Should Trailer Tires be Inflated To
    Trailer tires should always be inflated to their max psi rating so that you ensure that you get the full weight capacity and best tire wear characteristics. For example, the part # AM30630 that you referenced should be inflated to 90 psi to get it's full 990 lb capacity. I attached a review video for this wheel/tire plus a help article on trailer tires for you to check out.

  • 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.

  • 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. They have higher speed ratings, better sidewall flex, less heat build up etc. I do not know what tire size you have now though so I can't recommend a specific wheel and tire. I attached a link to a page that has all of the radial wheel and tire options we carry though.

  • 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). Most likely your wheels have a 4 on 4 inch bolt pattern, but you will want to measure them to confirm. 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.

  • What is the Difference Between 4.80-12 and 5.30-12 Sized Tires
    The main differences between the two trailer tire sizes you referenced are the outer diameter for the two and the capacities available. For the 4.80-12 tires they are 20.5 inches in overall diameter and have 785 and 990 lb capacities available. For the 5.30-12 they are 21.9 inches in overall diameter and have capacities of 840. 1,045, and 1,250 lbs. Larger tires tend to run a bit cooler and have higher capacities.

    The Kenda 4.80-12 Bias Trailer Tire with 12" Galvanized Wheel # AM30630 is rated for 65 miles per hour. If you routinely go above 65 miles per hour it will start to generate excessive heat. If it's one thing tires hate it's heat! All of the trailer tires in size 4.80-12 are rated for 65 miles per hour.

  • Replacement Trailer Tire Recommendatoin for Size 4.80-12
    I'd go with the tire size 145/R12 like part # AM10140 as this will give you a slightly taller and higher weight capacity tire that has automotive type tread for better traction and wear. This also has a higher speed rating that the smaller sizes like you have as well. While slightly taller the dimensions of the tire are close enough to what you have to prevent any clearance issues. I attached a review video for this for you to check out as well.

  • Can Trailer Tire Size of 20.5x8-10 be Replaced with 4.80-12
    The two sizes you mentioned have the exact same diameter of 20.5 inches. The biggest difference is that the 12 inch size you are considering of 4.80-12 is much narrower at 4.9 inches compared to 8.4. Clearance wise you'd not have any problems at all. If you have a 5 lug bolt pattern you'd need the part # AM30670 or if you have a 4 lug pattern you'd need the # AM30630.

  • Wheel And Tire Combination For A Marine Trailer
    A 155/80/12 is a typical size rating for a motor vehicle tire and not a trailer tire. A trailer tire comparable to the 155/80/12 would be a 145/80/12. As far as a wheel and tire combination, I recommend the Kenda KR25 ST145R12 Radial Trailer Tire with 12" Aluminum Wheel - 4 on 4 - Load Range D Item # AM31208. The 145/80/12 is only going to have about 1/2" difference in height from a 155/80/12 and it is going to be a little skinnier. Since the suspension on a trailer is mounted different...

    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...

This is an 8" diameter x 3-3/4" wide wheel, with a 4 x 4 lug pattern, and pilot diameter of 2.5". The tire is a 4.80/4.00-8 with a section width of 4.6". The outer diameter is 16.1".

    The tire size of 4.80-12 like what comes on the part # AM30630 is right at 3 inches narrower overall than the tire size of 185/80-13 so you would gain over an inch of inner sidewall room like you are needing.

  • 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...

  • Are there differences in the Kenda 4.80-12 Bias Trailer part # AM30630 and the 5.30 part # AM30790

The first is 4.80" wide and 20.7" tall and the second is 5.30" wide and 21.9" tall. If you are looking to upgrade size slightly and you have the room there is no issue substituting one for the other.

  • Replacement Trailer Spare for Tire Size 4.80-12
    The tire diameters are very different between the two sizes. The bigger size you have now of 4.80-12 is overall 20.5 inches tall and the older size 4.80-8 is 16.1 inches. Since that difference is split between either side of the spindle you'd have one side of the trailer sitting 2.2 inches taller than the other. In a very short-term emergency situation you could probably limp home with that but I would highly recommend matching the larger tire size for a spare with something like the part...

  • Do 4.80-8 and 4.80-12 Trailer Tire & 5-Bolt Wheels Have Same Bolt Pattern
    Not necessarily. While it's likely because the most common 5-bolt wheel pattern for trailer wheels is 5 on 4-1/2" you definitely want to measure to be sure you can go from your 4.80-8 with a 5-bolt wheel to a 4.80-12 with a 5-bolt wheel like the Kenda 4.80-12 Bias Trailer Tire with 12" White Wheel - 5 on 4-1/2 - Load Range C # AM30660.

  • Compatibility of Harbor Freight Trailer with Larger Tires
    The 4 on 4 inch bolt pattern is standard, so you can use a larger tire like the Kenda 4.80-12 Bias Trailer Tire with 12" Galvanized Wheel - 4 on 4 - Load Range C # AM30630. The fenders are the biggest issue to upgrading size on that type of trailer so if that isn't an issue for you then it will work well.
