Can Trailer Tire Size go From 165×6.50×8 to 18.5×8.50×8


I have a Triton snowmobile trailer with a tire size of 165×6.50×8 and would like to put 18.5×8.50×8 on it is there reason to not do this

You'd have to upgrade the wheel as well. The current size you have of 165x6.50-8 fits a smaller width rim at 5-3/8 inch whereas the 18.5×8.50×8 fits a 7 inch wide wheel.

So you'd want the part # AM3H325 for if you have a 5 on 4-1/2 inch bolt pattern or part # AM3H300.

The tire is going to be 50 mm wider and right at 2 inches taller.
