Tires That Slip on the wheels

This was discussed recently here. Watching Saturday's NASCAR Sprint Cup race, several cars had vibrations that they thought was because of a loose lug nut. They also mentioned that at THIS race, they could NOT use a tire "lock" that prevented tire slip on the wheel.
My point IS, "maybe" those red dots, on new tires, you know, the ones they align with the valve stems, "MAYBE" they're there to see if the tire has slipped on the rim, when they get a complaint of a vibration, after the car has been driven for some time?
"MAYBE" the OLD story of it being a "BALANCE" mark is PURE UNADULTRATED ********!!!:eek:
Comments, PLEASE.

Thinking or suggesting otherwise about that balancing mark on balloon tires is "unadulterated BS". :D Even the tire manufacturer literature back in the day stated THAT was the reason for the balancing mark along with the mounting ring stripe.

For those that know about and understand racing tire construction, rim construction, and the tire pressures we/they use, those folks understand about using bead locks. Below is my son's race car that you can plainly see the (orange) bolts used to clamp the bead to the rims in the first picture. In the following pictures, you can see the lateral forces placed on the tire, and the horsepower trying to twist the rim against the tire. Dirt can supply as much, --if not more traction than asphalt as evidenced by the bottom picture. Without a bead lock, the tire would definitely spin on the rim.

Something must be wrong with the steering, it doesn't seem to be going in the direction it's pointed! :D

If you think this one is moving 'slideways', let's get Steve Becker to show us some pictures of his ride takin' the fast way around on the cushion!! :D

Why not both?

(We used to get heaps of tires slipping on the rims on a ford escort with pinto motor and foot wide rims on the back. So much traction the rim spun smoke and wore down the beading until the air leaked out. Was funny.)
