Question:

I have a trail that has 12 tires and I need to pull a 4 stroke and a 2 stroke so I need 13 tire. Can I put 13 on instead of 12?

An ST145/R12 tire like the Kenda Karrier S-Trail # AM10140 measures 21.3 inches in diameter when inflated and is 5.7 wide. The smallest 13 inch tire is ST175/80R13 quite a bit bigger, measuring 24.1 inches in diameter and 7 inches wide. You'll need to measure to determine if you have clearance.

If so, and if you have a 5 on 4-1/2 inch bolt pattern there are a number of options available for this tire with different styles of wheel (if you are unsure of your exact bolt pattern you can refer to the linked help article which details exactly how to determine your bolt pattern).

For an ST175/80R13 tire, a load range D will have a capacity of 1,610 lbs, similar to the capacity of 1,520 lbs the Kenda Karrier S-Trail # AM10140 has.

Your options for a ST175/80R13 tire with a load range of D and wheel with a 5 on 4-1/2" bolt pattern are:
- Karrier ST175/80R13 Radial Trailer Tire with 13" White Wheel # AM31985
- Karrier ST175/80R13 Radial Trailer Tire with 13" Black Mod Wheel # AM31990
- Karrier ST175/80R13 Radial Trailer Tire w/ 13" White Mini Mod Wheel # AM31991
