OK, using an old archived post, I think I figured it out:
31 x 10.5 R15 is about 266.7/76.2/R15
2x + 15 = 31
2x=31 - 15
2x=16
x=16/2=8 (sidewall height in inches)
covert to mm 8 * 25.4 = 203.2
z / 25.4 = 10.5
z = 10.5 * 25.4
z = 266.7 (section width)
x / z = 203.2 / 266.7 = .762 (section height ratio)
Based on an earlier discussion about maximum tire size, I think the 31 /
10.5 R15s are the biggest that will not rub under full compression. Oh
well, I guess I have to wait for a suspension lift kit.
Thanks,

I tried that, but how do you convert the 31x10.5 R15s to metric sizes? I
tried just translating to millimeters, but that of course fails because
the metric reference is just to the tire section height, and the
standard measurement is tire diametere I think.
Thanks,

Just go to the DML tire&wheel calculator to see the exact size of each
tire
and wheel diameters. Bill
