17" Wheels w/ 225/45
Hi All,
I've picked up some 17" wheels for my 2nd track only set of tires. I know if I mount 225/45's on these wheels, I'll lose ~inch of the tires diameter (compared to stock). Besides an incorrect speedo reading and a similar effect of lowered gearing, what else can I expect?

Speed = Distance / Time
Time is fixed for each rotation - drivetrain won't spin faster or slower if weight is unchanged. Distance is increased per rotation. Thus speed is increased.
FWIW, if you have a heavy 18" and a light 22" that weigh the same, it won't matter. The rim size is NOT a variable in this equation. The only variables are Tire Circumference and Wheel+Tire weight. Depending on the extent of the deltas of both of these variables from the stock setup, either one could have a higher impact than the other.
