This is a eaxmple, probally not very accurate Mr.Cab Racing and winning with Mopars since 1964. (Old F--t, Huh)

My 315's on my Challenger are about 1/4" all the way around also with no issues. 7325935-100_1674[640x480].jpg (54 downloads) Last edited by 6PKRTSE; 08/07/12 04:41 PM. 1963 Belvedere 440 Max Wedge Tribute 1970 Charger R/T S.E. 440 Six Pack 1970 Challenger R/T, 528 Hemi 1970 Charger 500 S.E. 440 4 BBL 1970 Plymouth Road Runner 383 1974 Chrysler New Yorker 440 1996 2500 RAM 488 V-10 4X4 2004 3500 Dually Cummins 4x4 2012 Challenger R/T Classic.

There is less than a finger width at the wheel lip, inner side of the wheel tub/frame rail. 1963 Belvedere 440 Max Wedge Tribute 1970 Charger R/T S.E. 440 Six Pack 1970 Challenger R/T, 528 Hemi 1970 Charger 500 S.E. 440 4 BBL 1970 Plymouth Road Runner 383 1974 Chrysler New Yorker 440 1996 2500 RAM 488 V-10 4X4 2004 3500 Dually Cummins 4x4 2012 Challenger R/T Classic.
