well, this'd be the first i've ever heard of a 16.00 being 56"+. if that were the case, all the 'emasculated' mud trucks running these tires between their trailer and wal-mart would be yankin' their willy at the fact that the tire is 56" and not the claimed '53"'. i think the acual loaded D is closer to 52", but if i can get my deuce started this afternoon i'll measure.Or,
tire D = OD ratio x mph x axle x 336/rpm = 0.79 x 60 x 6.72 x 336 / 1900 = 56.33 inches
Tape measure time: Measure the center of the axle to the ground. ...
i agree, that is strange. but i also find it very odd that there is this very basic and very large discrepency among the knowledgeable members on this site. seems to me that this is a very simple sort of thing that would have been definitively proven long ago. i mean, people have been talking 0.85OD for years...... Not one single deuce TM that I can find talks of MF OD ratios other than 0.79. ...
it'd be nice if the people that 'know' would share how and why they know what they know.
anyone got a digital tach? put some tape on the jack shaft, put the 'case in N and tranny in 5, and get a reading off of the jack shaft at 1000 engine rpm and compare... i'd do it if i had one. can i borrow someone's?
