Re: Tire size for factory 20s on a stock '06 350
I think the miles would be recorded incorrectly. From what I have gathered...... the stock tires on the Goodyears were like 601 revs/mile. The 18" contis were 653 rpm and the BFG 285/65/20s are 599 rpm. Apparently the dealer can only adjust to the largest tire offered from the factory (20" Goodyears @ 601 r.p.mile. So the speedo can be close if you have the dealer do it.... but not spot on.
There are other ways of adjusting, I'm just not interested in them.
