anyone running that size?? any pics?? thanks

not 12.5 but 10.5 and they come right to the edge of the stock flares. Perfect size IMO.

31/10.50 fits great on stock rims
32/11.20 fits ok on stock rims
33/12.50 on stock rims hits my calmini bumper on compression, both front & rear of the lower a-arms on turning.
I have very well polished nuts on the front t-bar mounts..
31's on the 2000-2001 needs front mudflap trimming even if removed, removal, or change out to 2002-2004 style..

Yeah - you can adjust the turn stops to prevent polishing some of that.

The Shrock bumper clears even 35's though, so I'm ok there.
