Review of ST175/80R13 LR C Radial Trailer Tire 13 Inch Silver Mod Steel Wheel - KE49JR Video

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 difference between the letter D in your ST175/80D13 and the R in the tire size of the Wheel and Tire ST175/80R13 part #AM31985 that you referenced is the tire construction. D stands for bias-ply which is a less preferred tire construction,…

The most popular trailer wheel bolt pattern is the 5 on 4-1/2 inch bolt pattern and as far as we are aware the bolt pattern you mentioned is not used on trailers at all. So my bet is you probably have the 5 on 4-1/2 inch. I attached a help article…

There is no specific torque rating for shackle bolts. Basically for the middle bolt there should be enough free play in the shackles to allow them to move. Tightening the shackle bolts too much will squeeze the shackle straps against the leaf…

In general shackle bolts turning from use over time does not considerably wear out components. As long as the bolts are greased normally the movement from standard use would not cause them to wear out. The tension of the bolt and nut is loose enough…

The difference between an load range C and load range D tire in the same size is the capacity and psi rating. The two tires will still have the same dimensions and fit on the same wheel. The D rated tire has a higher capacity. For a ST175/80D13 like…

Kenda trailer tires are primarily made in China like most trailer tires. The only Radial trailer tires that I'm aware of that are made in the United States are the Goodyear Endurance line. Carlisle has a bias ply line of tires made in the States,…

Trailer manufacturers don't usually keep a record of parts like these that they install at the factory, so I cannot be sure as to the exact length of the shackle strap that would have come originally on your trailer. With this in mind, a 3-1/8…

Yes, a galvanized wheel will resist rust and corrosion better than a painted/coated wheel. This will apply to both the bead seat and face. In regards to cost, if you do not have access to a tire mounting machine or the means to use one for that…

We do carry the tire size of ST185/80D13 mounted on wheels so we do have a suitable spare. The part #AM3S334 is that tire size mounted on a galvanized wheel with a 5 on 4-1/2 inch bolt pattern. The D in the size instead of the R means it's a bias…

Whether a load range C or the greater capacity load range D, your will need to keep your tires inflated to their maximum psi rating for best performance and longest life. For a ST175/80D13 with load range D like the Loadstar Item #AM1ST77, the…

A higher load range tire has a higher ply rating but it will also produce a rougher ride and could have a psi rating that exceeds the capacity of the wheel or, more likely, the valve stem. The size you have now, 225/75-15 load range C, is rated for…
