Question:

I have a dual axle boat trailer that originally had st185/80r13 Karrier Loadstar tires on 13x5 inch aluminum wheels. The wheels got stolen off my trailer so i am replacing both wheels and tires. The closest i see on your website is your item # AM31994 which is a ST175/80R13 tire. Is that a suitable replacement? Other recommendation? thank you.

The Karrier ST175/80R13 Radial Trailer Tire with 13" Galvanized Wheel # AM31994 will work if the 1,610 lbs at 65 psi weight rating (per tire) is enough for your boat and trailer. This gives you a total weight capacity of 6,440 lbs.

If you need a bit more then we actually do have 185/80-13 size tires so something like the Loadstar ST185/80D13 Bias Trailer Tire with 13" Galvanized Wheel # AM3S334 would give you a slightly higher weight capacity at 1,710 lbs at 65 psi (for a total of 6,840 lbs).

I recommend sticking with the 185/80-13 tire size so you aren't really changing anything around.
