Question:
My boat trailer currently has a 185/80/13 tire on it. They are getting pretty worn and Im in the market for new ones. I do a lot of traveling and was wanting to go up to a 15inch rim if possible. How much bigger is a 205/75/15. I do have a couple inches of room between the tire and fender.

Expert Reply:
As far as height, a 185/80-13 tire will be about 24.4 inches tall. A 205/75-15 tire will be 27.1 inches tall. This is a difference of 2.7 inches, meaning that the larger tire size will be 1.35 inches closer to the fenders.
But you also have to worry about the extra width. A 185 has a section width of 7.2 inches. A 205 has a section width of 8.1 inches. This means that the larger size will be nearly a full inch closer to the trailer frame.
If the height and width are fine then you just need wheels that have the proper bolt pattern. I have included a link to a how-to article explaining how to determine bolt pattern.
Going to a larger tire size will not increase the capacity of the trailer. Also, the higher capacity tires could cause a stiffer ride than the standard size that was on the trailer. I have included a link to our informational article on trailer tires as well. I recommend going with radial tires such as # AM10245 if you go to the larger size. Radial tires track better and run cooler than bias ply tires.
