Against very good advice I went up one tire size for my 1998 GMC Z71. I went to a 285/75/16. I have had to buy new rims to accomodate the slightly wider tire and have a different offset in the front for proper tire clearence. My concern is that the speedo and stuff like that will be slightly out of wack and I was hoping someone here could tell me waht gears or such I would have to change to run these new tires and get the correct reading on the speedo.
Thanks in advance,
Blair
