Trailer Tires to Replace 155R12 Tires

Published 03/05/2015

Question:

Looking to replace my 155r12 tire as it is flat. Was wondering what the metric conversion was as I have read a couple different responses. 5.30 x 12 or 4.80 x 12? Which one is the most similar to 155r12

A 155/12 tire will be about 6.1 inches wide. The closest match is a 145/12 at 5.7 inches wide. I have included a link to all of the tires and tire/wheel combos we have in this size.

A 155 isn't a trailer tire size (unless it has an ST in front of the size). It is wider than all other 12 inch trailer tires which leads me to believe that if it is on a 12 inch trailer wheel it could be too wide for the wheel causing it to leak air.
