My 35" Mickey Thompson Baja MTZ's measure exactly 33" from the ground to the top of the tread. I'm not sure how many miles are on them, tread is probably half of what it once was. So their "35" is really only 34-ish anyway, minus the tread and bulge from being under-inflated puts me at 33.
Keep this in mind when you do get new tires - you need to recalibrate your speedo for the MEASURED size, with the amount of air pressure you want in them, not the manufacturer's stated size. Measure from the ground. When I programmed the speedo at 34.whatever it was off, when I reprogrammed it at 33" it was spot-on accurate with the GPS.
