" From: Ken Ames <ameskg@xxxxxxxxx> " " The 70 manual says the H78-14s have 749 revs per mile. " Nearest 14s are 235/75 (754) or 255/70 (749) and " for 15s are 235/70 (752 ) and 225/75 (743). my 'tire' program - provenance unknown - says Specification Sidewall Radius Diameter Circumference Revs/Mile Difference 235/75-14 6.9in 13.9in 27.9in 87.6in 723 0.0% 255/70-14 7.0in 14.0in 28.1in 88.1in 719 0.6% 225/75-15 6.6in 14.1in 28.3in 88.9in 713 1.5% 235/70-15 6.5in 14.0in 28.0in 87.8in 722 0.3% the revs/mile doesn't agree with ken's data but i don't know how it calculates it. many '80s rwd mopars - lebaron, mirada, etc; all volare derivatives afaik - have 15x7 steel rims that fit amcs perfectly, and would be just right for 235/70s but of course don't take amc hubcaps but would take 15" amc wheelcovers. i imagine 15x7 mopar aluminum rims would fit just as well but haven't tried them. ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list
