  Strange. It would appear that we can't trust the numbers on the sidewall!!!
Take a look at the very first tire - they claim it is a 35x12.50, and yet they
say right there that its only 33.5" tall! Weird. (What happened to truth
in advertising?) ;-)

  I just went outside and measured my 235/70R15's. They were between 26 and 27
inches tall, not the 27.95" (28") they are supposed to be! Some of that is
probably because the tread is worn down, and they might need to be inflated
a little bit, but still... Is this practice common amoung tire
manufacturers?
The whole idea of putting those numbers on the tire is so we can get the right
size! If there's no correlation between those numbers and the real
dimensions,
they're worthless.

  Anyone have any ideas?
