Note: The overall capacity of this tire-and-wheel assembly is limited to the lowest rated component. Do not fill your tire to a pressure greater than that indicated on the tire itself or on the wheel that it is mounted to.
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.

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.)

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.)

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.

Today we will be reviewing part number AM30670. This is the Kenda 4.80-12 bias trailer tire mounted on a 12" Dexstar galvanized wheel. We'll start with the rim dimensions on this wheel. To measure the rim diameter, measure inside-to-inside which should be 12". The width of this wheel is 4". This wheel has a bolt pattern, which is 5 lugs, 4-1/2" between the lugs.
The best way on a bolt pattern that is of odd number of lugs, is if you will draw a circle through the center of each bolt hole and then we will measure the diameter of that circle, that will give you the bolt pattern. So if we measure from the center of this bolt hole all the way across to the other edge of that circle, be 4-1/2". So this wheel would be a 5 on 4-1/2" bolt pattern. This wheel has a weight capacity of 1,250 pounds at 90 psi. It uses a wheel bolt size of a 1/2"-20.
Another critical measurement is the pilot hole diameter, which is the large center hole in this wheel. This will go over the hub on your trailer. If we measure across, the diameter of that would be 3.19". This wheel does have a corrosion-resistant galvanized finish. Now we move on to the tire.
The tire on this is a Loadstar, size 4.80-12. This tire is a load range C tire, which is a 6 ply rated tire, has a maximum load carrying capacity of 990 pounds at 90 psi. This tire is a bias constructed tire, which means the belts on this tire will run this way the length of the tire that will give a little bit firmer ride when compared to a radial design tire. One last measurement we're going to do is the overall diameter. And if we measure all the way across, will give us 21".
This tire/wheel combo will come with a limited 2-year warranty. And that should do it for part number AM30670.

Just as ordered and received quickly. Recomended pressure is 90 pounds but one was 72 and the other 77. Would have been nice if received with 90. Otherwise I am completely satisfied with all my transactions with Etrailer thus far.50266

I upgraded my 8" trailer wheels to 12" wheels. The trailer and boat ride much smoother with the larger wheels. I no longer feel every little bump in the road. I normally tow this boat to sailing regatta around 25 miles. 49935

Not much to review because this is just a rim/tire but delivery was as promised and the quality of the product was very good. Additionally, I should point out that the information on their website was very good in determining the correct size of the rim to match the trailer.37555

I put these tires on a boat trailer that I have been fixing up, and they have done well on the fishing trip that I just made as well as the 3 short runs to a local outboard repair shop and to a trailer shop. So, I think it's a little too soon to judge durability. They handle well on the road. They were well packaged in separate boxes (I ordered 3 and got 3 boxes), they shipped very quickly, and they came inflated. The rims are so shiny that they look more like they are chrome-plated rather than galvanized. It's not easy to get 12" load range C tires locally, so I am pleased with my purchase, and the price was right, too.35576

Everything was very well packed and in perfect condition and it's here just days after ordering. These will last longer since they are galvanized and they are heavier duty so I can carry more. I also have 2 spares now. I can carry a load of firewood with extra confidence. 27346

I needed tires and rims for my boat traler bad. I bought the boat and trailer at the end of fishing season last year and the previous owner must have had some issues backing the trailer up bothe rims were kind of shot from hitting curbs. I shopped around everywhere and thought everyone one was way to high with there prices. I found this place on the internet and Im glad I did. The people were nice on the phone,the prices were great, shipping took no time at all and the best thing was opening up the shipping box and seeing the tires. They were on a better quality rim and tires are just fine. Theres not many places like this that treat you nice and send a great product.11010
