Question:

I have a ShoreLandr Boat Trailer # SSB18117S. The tires that are on it are. ST 155 80 R 13 These Tires are no longer made. I was told by the Shorelandr people that I should replace them with tire size 5.30 X 12C . Size 13 down to 12? Do you have a better suggestion? Thank you

Expert Reply:

A 5.30 X 12C tire is going to be your best replacement. If you need the 4 on 4 inch bolt pattern # AM30780 is a good option, or # AM30820 for the 5 on 4-1/2 inch bolt pattern. These both have the wheel and tire included, which you'll need, since you will be decreasing the size of your rim.

The reason I suggest going with the 12 inch rims is because the smallest 13 inch tires available, such as # TTWTRTM1758013C, are 175/80R13 which is quite a bit larger. Your current tires are approximately 22 inches in diameter where sticking with the 13 inch rim on the larger tire will put that about 24 inches. It will also increase the section with by about an inch.

However, if you have the clearance on your trailer they will work. You want to make sure you have at least 4-1/2 inches of clearance from the tire tread to the inside of the fender to allow your trailer suspension to move freely when traveling. As well as about 2 inches between the tire wall and the inside of the wheel well.
