When choosing a speedometer gear should I go by the measured tire size or what is stated on the tire? Example, I have 265/70R17 which the company says it's a 31.7" tire, but I measure (at 30 PSI) 30.5".
Back in the day, there weren't metric tires and I would have said, go with what's listed on the sidewall. That said, I might split the difference and go with 31 in this case.
