Tire Conversion?
How do you convert tires like 235/75R15 to inches. I'm looking for tires for my XJ but I don't know how to convert the specs to inches. Thanks in advance.

Just do the math to convert the metric to inches...
235 = tread width in mm
75 = sidewall percentage of tread width
15 = wheel diameter
235 / 25.4(mm/inch) = 9.25
tread width x sidewall percentage
9.25 * .75 = 6.94
6.94 * 2 = 13.875 (two sidewall heights)
13.875 + 15 (wheel dia) = 28.875
