What Is The Proper Tire Pressure For Special Trailer ST Tires?  

With trailer tires you have to run them at their max PSI listed on the sidewall. So for a tire size ST175/80D13 in the Load Range of D like the part #AM1ST77 that you referenced you'd need to inflate them when cold to 65 psi. This ensures you…

On a towing setup you are always limited by the lowest rated component as the overall towing capacity since that is the weakest point. When it comes to trailer tires you always want to have them inflated to their max psi when cold. Not only do you…

I did some checking and the hub/drum we offer that will work for you is the part #8-430-5UC3. This uses the same bearings as the 8-415 and will be an exact fit aside from the fact this is a non-ABS setup and the 8-415 came in an ABS setup and non-ABS…

From what I could find it looks like your 122R (red) and 122Y (amber) lights measure 3.75" x 1.70" x .81". We don't have any replacement lense directly for the GLO-BRITE lights but we do have some similar lights that you could use…
