Will someone measure the tire size and give me actual measurements? Thanks in advance!

You actually believe the MFG's propaganda? Look up the specs for your current tires, then go out and measure them. KM2's are known to run small. Betting 33.5" is actual for these...

just do the math:

315 millimeters = 12.4015748 inches
12.4015748 * .75 = 9.3011811
9.3011811 * 2 (for rubber height above and below rim)= 18.6023622
18.6023622 + 16 = 34.6"

Again, that is a conversion for the mfg's listed height. NOT the actual measured height. Mounted, and with the full vehicle weight on them, they are not 34.6".

MTR/K's measure out closer to the listed height, KM2's do not. If you want a 35" KM2, order the 37's...

But at least the thread got bumped so maybe some folks running these will chime in with actual measurements.

bah, just inflate to 75 psi* and you can get your .5" back.


*note: not actual advice...

I have the 315/75R16 KM2's on a set of 16x8 Black Rock wheels. My tires measure just at 34 inches under weight.

Yeah, most tires seem to run well undersize once under load. My 36" Iroks were closer to 35", 315 Buckshots were 33.5", 305/70R17 Buckshots were around 33". Really, if you take whatever number the mfg gives you, and minus in the ballpark of a inch, thatll be about where it is. If BFG claims 34.8, then itll probably be in the 33.75 ballpark.
