Re: [ihc] Tire RPM @ 70 mph

["James Lidberg" <jameslidberg@xxxxxxxxx>]

Joel,

Thanks for your calculation.

Is this calculation for the wheel RPM?

The little rollers inside the wheel bearings are rotating much faster aren't they?

Like 10X to 30X wheel RPM?

Depending upon their diameter and race's diameter?
