Result: 4.80x12 tires

Yes, the Kenda Karrier S-Trail ST145/R12 Radial Trailer Tire #AM10140 referenced in your question will fit the same 12 inch wheel with a 4 inch width that your existing 4.80-12 size tires are mounted to. Just note that the ST145/R12 tire will be…

The 5.30-12 tires, being wider, are going to make more contact with the road. This means that the noise, and heat build up will be higher than a 4.80-12 tire but the rolling resistance will actually be less because the tire is larger diameter. The…

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…

The difference in overall diameter between 4.80-8 and 4.80-12 size trailer tires is about 4-1/2 inches. A smaller tire will clearly not create a clearance issue around fenders where a larger size could. The two tires' widths are fairly close to…

I have several options to upgrade 4.80-12 wheel/tires on a trailer without replacing hubs, ranging from 13" - 15". The best option will really come down to how much space you have available and this will be different for each trailer. The…

The Fulton Plastic Fender with Top Step, part #F008553, does not come with mounting hardware. Fulton does not provide mounting bracket kits for the fenders. You can use your fenders original mounting brackets or use the Redline Galvanized Steel,…

Since both a ST145/R12 size tire, like the Kenda Karrier S-Trail #AM10130, and a 5.30-12 size tire, like the Kenda K353 #AM10068, fit a 12 inch wheel, a ST145/R12 size tire can replace a 5.30-12 size tire. Keep in mind that these tires do have…

The closest metric trailer tire size to a 4.80x12 is going to be a 145/80-12. The typical diameter of a 4.80x12 tire is 20.5 inches. On a 145/80-12, it is 21.3 inches. So the metric size will be a little over 1/4 inch taller. Make sure to measure the…

Load range B trailer tires are going to have a lower capacity than C load range tires. Basically that, psi rating, and the ply rating are the only differences. A higher load range tire would last a little longer than lower load ranges of the same…

The two tire sizes are similar, but the 145/80-12 will be a bit taller at 21.3 inches vs. the 4.80-12 which has a diameter of 20.5 inches. Aside from that they are very similar and both fit 12 inch diameter rims that are 4 inches wide. The radial…

I've actually answered a similar question on this before and found: In my research I found that the grease seal you are looking for could have an inner diameter of either 2.24 or 2.12 inches and an outer diameter of 3.37 inches when measured with…

The main reasons why trailer tires blow out is heat generated from under inflated tires and overloading the tires. Trailer tires should be inflated to the maximum psi indicated on the tire. A tire in the same size but with a higher ply rating would…
