Default camber thrust illustrated

Lest you think this is some esoteric phenomenon, I have some aggressive camber on my car and sticky tires. For the past week I have been tiling my garage floor and after a couple of days figured it was safe to bring my car in. Guess not, here, to the right in the second picture, is where my right front tire sat. I think the fix will be to rip these out and epoxy in a molding at the edge. Don't really know how long to wait otherwise.

A good illustration, and thank you for prompting me to do some reading/revision on the subject. Reinforces some of the reasons why neg camber on the front improves handling and particularly turn in so dramatically (it's not only the tyre sitting more level on the road with body roll), and how the dynamic camber added/subtracted by higher caster settings help mid corner speed.

About 2.5 degrees. Hoosier actually recommends 3 degrees. The tires are 255's with a treadwear of 100. I must say this takes considerable force to do this. Once I set a tile in place I just can't move it and it's destroyed if I try to pull it back up and reset it. The adhesive is extremely aggressive, even in shear.

I've done this tiling in phases and the rears moved the tiles a little where the tiles had more time to set. They'll be OK with some fill. I've tried wedging some weights to get some push back in and nothing happens.

I don't entirely understand the forces at work here. The camber constitutes a vector with vertical and horizontal force. So this separation would be due to the horizontal force. And the inside of the tire would be compressed a little more so that would want to spread out too. And both wheels on the same line of tiles doubles the force.

Everything was perfect before I parked. Sigh! At least I have more tiles to fix this. JUST HAVE TO BE PATIENT, THINK I WOULD HAVE LEARNED THIS BY NOW.

I did a brake job on my 80 a few days after I tiled my garage, and had three or four tiles buckle from where the rear tires pushed them. Had the front of the car jacked up, the rear tires on the floor. I reset what tiles could be salvaged, and replaced the few riped ones. I put down plywood and finished the brakes. Haven't have a problem since.

These are Armstrong VCT with the correct adhesive. I was worried about backing in and out and braking so I put down some molding front and back to hold things together. Never thought about this, though!

VCT tiles here too. This shot gives you an idea of grippy tires on not quite cured tile cement.
