how much height difference between a 175/65/14 and a 185/65/14
asked by: Gary
Well first, neither of those are common trailer tire sizes. Though they could be light truck tires which are sometimes used on trailer applications. Anyway for 175/65-14 the section width is 6.895 inches and the diameter or height is 22.96 inches.
A 185/65-14 is 7.289 inches wide and 23.47 inches tall. So it is just over half an inch taller. I have also included a link to the right to an FAQ article that explains how to determine tire diameter for you.
