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"

@Scott Awesome, glad to hear that!


Very happy with these tires and service! Straightforward ordering and delivery. George from etrailer reached out to me following a glitch in the payment process that happened because I had changed the address on my credit card as I was moving overseas. I was also dealing with a very tight time constraint, but the tires were perfect and arrived on schedule. Installation was no problem, and I had a smooth 730 mile journey from Chicago to Baltimore to deliver the boat and trailer for shipping. And now the boat, and the tires, are here with me in New Zealand :).


Just what I needed! These wheels and tires are for an old Sea Lion trailer that holds an old Rhodes 19 sailboat. I will not have time to restore the boat this year - too many other boats for customers - but it will be ready for next Spring. I will sail the vessel on Lake Champlain and will haul it up there on these new tires. As I fully prepare the trailer, I will be getting more bits and pieces from etrailer - including a spare wheel and tire and mount.

I have used etrailer for many years. I own 5 trailers myself - and occasionally restore or improve my customer's trailers. Also, I purchased my trailer hitch for my 2018 Forester from etrailer. I have always been perfectly pleased with the service and products.


These tires and wheels worked great as a replacement for my 1977 bass boat trailer. Very satisfied with the purchase.


Ordered brand new tires wheels and one doesnt hold air leaking around valve stem. So now i have a customer to pick up their jetski to put away and i have to tell him the new tires i got for him leak!!!! Un real why arent these checked before ship?

Jenny N.


I am sorry that it is not holding air for you. Customer Service will be in touch so that we can have it replaced for you.


Switched from a 5.7-8 to a 5.3-12, and I was worried about clearance, but I still have +/- 2 inches under the fender. I also like the profile of the bigger tire for the trailer. I always love etrailer! Quality parts and quality service everytime!


Great looking tires and wheels. Great price. Most importantly, fast, efficiant service and super quick delvery.



Still look great with no sign of wear


Items came sooner than estimated, very well boxed! Both wheels and tires look great, looking forward to getting them put on my log splitter!


Excellent quality, fast shipping. I am restoring a 1992 Jayco popup and I bought, wheels and tires, trailer hitch and a 4-way flat to 6 square wiring adapter for the camper. Great experience...I plan to buy from etrailer again.


Picked up 2 spare tires for this trailer from on the way to Phoenix, AZ. There are 2 spares on the trailer and a special paint job. Harbor freight trailer with 8 inch tires. 2011 Smart 4 2.


The product looks good in the pictures. The tires were just as expected. The set was delivered with equal tires pressure. The wheels are another story. The wheels are muddled and appear to be very poor casting with lots of slags. The bolt holes were heavily burred and lacking a clean machining as well. One tire was mounted with the stripes outward and the other with stripes inward. I am hoping this is just cosmetic, however, I prefer my camper to look nice and the same on both sides. The set will complete a 600-mile trip soon. I hope they perform better than they look.


Customer service does exist on the Internet! Etrailer delivers at a level of service that I did not think existed on the Internet. The team at etrailer rushed my tires out and saved our Memorial Day camping trip. I got follow ups every step of the way, and a very prompt response when I expressed the urgency of my order. The tires are great, and the proper rating for my trailer (they are nearly impossible to find at the big chain stores). After hearing about the site on several forums I decided to give them a chance and will never buy my trailer products anywhere else again!


Fantastic - received unbelievable customer service that walked me thru the whole process of picking the right tire and rim. Even gave advice for a broken stud.
Gave new Life and Ride to a classic older Motorcycle hauler - Ready to hit the road.


Replaced old original tires on my boat trailer along with rusted rims. Tires look great.
Received my order 2 days earlier than expected.
Once again etrailer with great products and outstanding customer service!
Won't use anyone else.


Whees/Tires came as described! Not knowing much about trailer tires/wheels, etrailer had all the info I needed! Easy to understand, read, and find!


Super fast shipping, order at noon 1/8 - received before noon 1/10. Product as expected, time will tell how they ride and wear.

Scott K.


Very Happy, Tires have worked out perfect.


The wheel and rim look very good. The rim was over sprayed and had drips which is the only reason I gave 4 stars and not 5 stars. Other than that, issue it looks very good.


wow......incredible deal on these tires / wheels and if that wasn't enough, the fastest delivery imaginable !
Of course when In built this splitter 25 years ago, I just modified some wheels to fit it by using washers and filing out the lug holes.....NOW, it's done right !

Many thanks, I will be back !


Always a treat to open the box that new tires and wheels come in from etrailer. The galvanized rims were so shiny and bright they'd look great just hanging on a wall. Never had any issues with wheels and tires from this seller. I will be back again soon as I just purchased another used boat trailer with 8" wheels, (I prefer 12" wheels and tires for the smoother ride).

Allan C.


One year later and the wheels and tires are still working perfectly. No leaks, no flats, no wobbles.


Couldn't find the size of tire I needed on the island. For a little bit more I figured I get the tires and rims together. Took a few minutes to pop on. Ready to go fishing!


Happy with my order, and thanks for the fast shipping!


Tires are great !! Delivered on time keep up the service


Excellent customer service, fast accurate shipping, super price! Two new wheel tire assemblies and a light kit, delivered in two days....made pick up of my 1971 Mariner 2 + 2 in Baltimore possible! Thanks guys!


Delivery was fast and the tires were as ordered. Great deal on tires & rims. Will install them on my boat trailer in the Spring. Impressed so far !


Very nice upgrade from the 4.80 tires I had on the boat trailer. Fit my fenders nicely. Heavy duty set.

  • How to Determine the Correct Over-Under Conversion Kit
    In order to determine whether you need the Dexter Trailer Springs Over-Under Conversion Kit # K71-384-00 (2-3/8") or # K71-385-00 (3") you will need to measure the diameter of your axle. If you get 2-3/8" then you need # K71-384-00 and if you get 3" then you need # K71-385-00. As far as tires/rims are concerned you will want to ensure you have a 4 on 4 bolt pattern (which is the most common 4 bolt pattern) I have included a link to an article that can help you with determining this.

  • Can 4.80-12 Tires Be Upgraded to 5.30-12 Tires
    The 5.30-12 tires, like the Kenda Bias Trailer Tire # AM30790 you were looking at, have about a 1-1/2" larger diameter than your 4.80-12 tires, so if your fender can accommodate 3/4" more tire and still retain 2" of height clearance (to account for suspension travel) you'll be good to go!

    The Loadstar ST175/80D13 Bias Trailer Tire with 13" White Wheel - 4 on 4 - Load Range C # AM3S120 is the largest wheel we carry in that bolt pattern. This will give you a 24 inch diameter with a 6.6 inch width. The Kenda 5.30-12 Bias Trailer Tire with 12" Galvanized Wheel - 4 on 4 - Load Range C Item # AM30790 is the next largest with the diameter of 21.9 inches and a width of 5.3 inches.

  • Can Trailer Tire Size 4.80-12 be Replaced with 5.30-12
    Yes, you can as the size is very similar and it's a very common tire size change. So if you had a 5 lug wheel currently you could use the part # AM30850 or for a 4 bolt wheel you'd want the part # AM30790 which also has a galvanized wheel and same tire. Or you could reuse your current wheels and mount the part # AM10066 to it.

  • 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...

This radial tire has a ply rating of 8 and has a 1,220 pound maximum load capacity at 65 psi.

  • 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. It sounds like...

  • What PSI Should Trailer Wheel and Tire be Inflated to In Size 5.30-12
    Sounds like maybe you have more than one brand of tire on your trailer and there is multiple PSI requirements based on that. It is correct that you should always run the max pressure in the tire listed on the sidewall otherwise capacity is diminished and likelihood for failure is increased. For a wheel and tire in your size of 5.30-12 and a wheel bolt pattern of 4 on 4 like you need the part # AM30790 would be a really great option.

  • Replacement Trailer Tire Recommendation for a 2004 Bass Tracker Panfish Boat Trailer
    It sounds like you are overloading your current trailer tires or are pretty close to and should upgrade to a 5.30x12 tire with enough capacity. For that you would want the # AM10068 which has a capacity of 1,250 lbs at 105 psi per tire. Special trailer tires should be inflated to their maximum air pressure. 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...

  • Recommended Replacement 12" Wheel and Tire for 4 on 4 Bolt Pattern
    The size of your tire isn't necessarily going to effect the heat that they're going to generate, but tires that are not properly inflated will create more contact with the road and create more heat-which is the largest cause of tire malfunction. Also, there could potentially be 12" wheels with tires that are the same diameter as a 13" wheel, so in the interest of keeping things simple you're probably going to be best served just sticking with what you're currently using, and not creating...

  • Can Bigger Tires and Wheels be Used on a Aluminum Jet Ski Trailer with 145/12 Tires
    You might be able to use a larger tire as long as there is space all around the existing tires for the larger size. The next size up from your 145/12 size is going to be 175/80-13. This tire size will be 1.3 inches wider and 2.8 inches taller. What this means is you will need more than 0.65 inches between the sides of the tires closest to the trailer and the trailer itself. And you will need more than 1.4 inches from the tops of the tires to anything above them, such as fenders. If you...

  • Are there differences in the Kenda 4.80-12 Bias Trailer part # AM30630 and the 5.30 part # AM30790
    The difference in the Kenda 4.80-12 Bias Trailer Tire with 12" Galvanized Wheel part # AM30630 and the Kenda 5.30-12 Bias Trailer Tire with 12" Galvanized Wheel part # AM30790 is the size of the tire itself. 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.

    In the 10 inch wheel size the 20.5x8.0-10 that you have is the tallest size overall at 20.5 inch. If you wanted to bump up to a 21.9 inch overall diameter tire you could go to a 5.30-12 tire with something like the # AM30790 if you have a 4 bolt pattern or # AM30820 if you have a 5 bolt. This would be a narrower tire as well so there wouldn't be any risk of clearance issues with the trailer frame.

  • Wider Tire Replacement for 4.80-12 Trailer Tire Wheel and Tire
    The 4.80-12 tire has a section width of 4.80" and an outer diameter (when inflated) of 20.5". The 5.30-12 tire has a 5.3 inch section width and outer diameter of 21.5 inches, so it will change both the height and width of the tire. If you have the space, the upgraded size will gain you some weight capacity. If you want to keep the 4.80-12 size, I recommend the Kenda 4.80-12 Bias Trailer Tire with 12" White Wheel - 4 on 4 - Load Range C # AM30620. This combo is rated for 990 lbs at 90...
