- Centrifugal Force on Rotating tire / wheel

Heya PhysicsForums!

Remote Control Car toy tires and wheels.

a 4" tire/wheel rotates at 8400rpm at 100mph.

Am wondering how many "g's" the tire "experiences" at that rpm; I imagine it being hundreds of times (if below is accurate am WAY off with my guess)

Using a centrifugal force calculator and the following values (sorry about units)

Mass (of just tire) = 250 grams

radius = 2 inches

tangential velocity = 100mph

equals a force of 9835 Newtons and centrifugal acceleration (I guess this is the value am interested in?) of 39,340m/s/s

so for G units is that the centrifugal acceleration of 39,340 / 9.81 = 4,010g?

meaning the tire experiences 4000g's of force perpendicular to the axel? (if so omg that is some strong glue holding the tire to the wheel lol)
