Re: [ihc] Tire RPM @ 70 mph



Joel,
   What if you could adjust the diameter of the tire from the interior of
your truck? Like if you had an adjustable Pi button?

Jim,
just some rough numbers...
70 mph ~ 103 ft/sec
31" tire is  pi*D or 8.1 feet in circumference

103/8.1 = 12 rev/sec

or 720 rev/min.

I think you're okay.

Joel
