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.


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.


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!


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.


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!


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.


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


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.


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!


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.


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.


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.


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 !


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.


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!


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!


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!


I wanted a spare tire for my boat trailer. This model is better than the originals. And cost is the same as getting just a new tire at the local tire shop. The designation 4 on 4 means 4 bolt holes on a 4in diameter circle. Measure across the hub from one bolt hole to the opposite side hole.


This is my forth time that I have purchased tires and wheels, except I usually buy the white painted ones. These galvanized junk rims look horrible! I am almost afraid to use them. This is my mistake by trying to save a few bucks! Should have a better description on how poor the quality is. Very disappointed!!


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 !


I haven’t put them on the trailer yet but they look good and we’re a great value.


Well packaged, on time snd quality prod uct

  • Are All Galvanized Wheels Hot Dipped?
    The galvanized wheels from Americana are always hot-dipped. Some of the Taskmaster wheels use a PVD (Physical Vapor Deposition) coating that is a black finish and those wheels are not hot-dipped. We do specify the wheels that use the PVD and they are black finish versus light gray, so you will know the difference. The Kenda 5.30-12 Bias Trailer Tire with 12" Galvanized Wheel - 4 on 4 - Load Range C # AM30790 you looked at are Americana wheels that are hot dipped.

  • Tire Pressure for Kenda 5.30-12 Bias Trailer Tire with 12" Galvanized Wheel AM30790
    The tire in tire and wheel combo # AM30790 is rated for 1,045 pounds at 80 psi. Trailer tires should always be inflated to the maximum psi indicated on the tire. This is because trailer tires have a thick sidewall and if under inflated it can cause the tire to generate excessive heat and lead to failure.

  • Does the Center Pilot Hole on a Trailer Wheel Have to Be an Exact Size to Fit Over the Hub
    There are 2 different types of wheels you will find on a trailer: lug-centric and hub-centric. If your wheels attach to the hub using lug nuts then it is lug-centric. This means that the wheel centers on the hub using the lug nuts. If your wheels attach to the hub with wheel bolts and no lug nuts then it is hub-centric and the wheel centers on the hub using the center pilot hole. If you have the first type, lug-centric, then the pilot hole can be larger since it centers on the hub using...

  • Trailer Tire Inflation Pressure and Speed Ratings and How Do They Affect Tire Performance
    All trailer tires, regardless of brand, size or construction, should ALWAYS have a cold tire pressure as is listed on the tire sidewall. This maximum cold psi pressure is required for the tire to meet its weight rating. It is never appropriate to under- or over-inflate a trailer tire for any reason. There is no benefit to doing so and the incorrect pressure can lead to uneven tread wear, reduced capacity, excess heat and tire failure. Always start your travel day with your tires inflated...

  • Recommended Replacement Tires for 5.30-12 Load Range D Tandem Axle Pontoon Boat Trailer
    I have a solution for you, but I can't recommend going down to a Load Range C tire with your trailer in this case without knowing the exact weights. However, if you wanted to go with a radial tire you could use the Kenda Karrier S-Trail ST145/R12 Radial Trailer Tire - Load Range E # AM10140; these are 21.3" in diameter so they've close in size to your 5.30-12 tires that are 21.6" diameter. You could mount these on your existing rims. With all of that said, since you've got a tandem axle...

  • Trailer Tire Miles Per Hour Rating
    That is correct, all of our 12 inch, 4 on 4 trailer tires are rated for maximum highway speeds of 65 mph. This is a normal speed rating for trailer tires. I recommend our Taskmaster brand trailer tires, such as the Kenda 4.80-12 Bias Trailer Tire # AM30620. This tire has a rating of load range C. If you need a 5.30-12 tire, you could use Kenda # AM30790. I have attached a link to all of our 12 inch, 4 on 4 trailer tires.

  • 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...

  • Wider Tire Replacement for 4.80-12 Trailer Tire Wheel and Tire

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...

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.

    Since you have the clearance to go to the larger trailer wheel and tire size you certainly could. The overall diameter difference between the two sizes is large enough that you wouldn't want to plan on using them together on a trailer. I would not recommend the use of a 4.80-8 tire as a spare on a trailer that is using 5.30-12 sized tires as the diameter difference is almost 5 inches. Best option is all the same size like the part # AM30790 which is a 5.30-12 trailer tire size mounted...

    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...

  • Recommended 5.30-12 Tires for 2,000 Lb Boat and Trailer
    I do have some great trailer tire options for you but the total weight capacity of the tires on a trailer does not need to account for the loaded weight of the trailer, at least directly. The reason for this is that 10-15% of the trailer's weight is carried on the vehicle via the tongue. If you're looking for a greater margin of error however I can understand that and the Kenda 5.30-12 Bias Trailer Tire with 12" Galvanized Wheel part # AM30790 would be a great option.

The 4.80-12 bias tire is 20.7 inches tall and 4.9 inches wide. The 145R12 radial tire is 21.3 inches tall and 5.7 inches wide.

  • What Torque Rating Should the Lug Nuts of the Kenda Wheel and Tire Combo Be Tightened To
    For the wheel included with the tire and wheel combo # AM30790, the specs for the wheel indicate that the lug nuts should be torqued to 50 to 75 foot pounds. You should re-torque them at 10 miles, 25 miles, and 50 miles, and then periodically after that. I attached an FAQ article on trailer tires for you to check out also.
