I'll say it again, my Terrabites are the standard version, not the HD Aramid cord version (I was told those run slightly small). I called RMATV before ordering and was assured the tires ran true to size, mine are 100% 32" at 12-13#. If you're measuring the tires on the machine, you'll get slightly less top/bottom from vehicle weight, mine will still measure over 31.5" under load. Maybe I got lucky, but I doubt it since Rocky Mountain assured me they'd be 32". I wouldn't go with 33" Terrabite, I'm positive they'd rub on my machine while turning and stroking the suspension. These tires are way way way taller than the stock tires, easily 3.5" taller.
