Expert Reply:

The proper tire psi for trailer tires (ST) is listed on the tire as the max psi. Trailer tires are always to be inflated before a trip to the their max psi. Overfilling or underinflation will lead to premature wear or failure.

I was able to confirm the tire size is ST145R12 but not the specific tire used to give you the number. For example the Kenda Karrier S-Trail ST145/R12 Radial Trailer Tire - Load Range D # AM10130 has a max psi rated at 65 psi. This can vary by tire so look at your tire sidewall for the listed max psi.

Answer 1

The difference between the two trailer sizes you referenced is that the 5.30-12 will be about 1-1/2 inches taller than the 4.80-12 and would have more capacity. As long as your trailer has the clearance for a slightly taller and wider tire a 5.30-12…

Answer 3

Different size and bolt pattern wheels that take the same tire size will have different psi ratings. If your existing wheels are rated for 65 psi then it is less likely that they would also be rated for 80 psi which is what an ST225/75-15 load range…

Carlisle and Kenda trailer tires are about the same in terms of quality. We only sell Kenda currently so I'll try not to give you too much bias...but the Kenda Karrier S-Trail ST145/R12 Radial Trailer Tire #AM10130 that you referenced is very…

For a single axle trailer, you want the shackle strap to be able to move so that you have the spring deflection needed for your suspension. Angled like the photo or even almost vertical is fine you just don't want the shackle strap to bind and…

Answer 6

The tire size of 145/80-12 fits on the same wheel size as the 5.30-12 so yes you could go to the 145 size. It's actually a tiny bit shorter in diameter too so there would be no need to check for clearance either. For a radial in the size you want…

Answer 9

The best trailer tire to replace your 4.80x12C would be the Kenda Karrier part #AM10130 which has a higher weight capacity, is a radial, and has the higher speed rating of 81 mph instead of the usual speed rating for this size of 65 mph. The higher…

Answer 10

Yes. A 4.80-12 tire and a 5.30-12 tire will both use a 12x4 inch wheel. For your tires, I recommend the Kenda Karrier S-Trail ST145/R12 Radial Trailer Tire - Load Range D #AM10130. This is the only radial tire we carry in this size and it has a rated…

Answer 11

Bias ply and radial tires are good at doing different things. Bias ply tires have a sturdier sidewall and are thus better for off-road and agricultural applications but still work just fine on pavement. Radial tires track better and run cooler than…

Answer 12

A 145/80-12 tire size, like #AM10130, will be 5.7 inches wide and 21.3 inches in diameter. To compare, a 5.30-12 tire, like #AM10068, is 5.5 inches wide and 21.9 inches in diameter. Since the 145/80-12 will be a little wider (by only 0.2 inches) you…
