Damn, thank you for that info. A wheel swap sounds like the logical thing
to do. I can also look at different tire sizes at the same time. My
p215-75-15's have a 27 inch overall height. If I swap rims, I can also go
with a lower profile tire, get the height down to 25-26 inches, and also
increase my rear end ratio. am I correct?
