Negative camber tires

no.

I'm not understanding how those help. You're just changing the angle at which the treadface is flat to the pavement. How does that change what happens under suspension travel or body roll?

We would of course want to run them opposite of his intention.

This.

Seriously, WTF.

I don't know if they're still available, but in the 90's, you could buy recaps with the tread cambered for stock tire/suspension circle track classes.

Not a new idea. I've thought of it myself. Pre-camber the tires to account for vehicle body role and tire carcas deflection, thereby optimizing tread face contact with the pavement.

But I find the claims of increased fuel mileage suspect. Don't see how that can be.

Cambered tires, and especially a-symetrical tires or wheels impart thrust to the smaller diameter size. Railcars exploit this to keep themselves centered in the rail track and not have to ride the flanges. The wheels match in size and angle, so the thrust is equal and the railcar centers. Same would apply to an automobile. But this thrust increases drag, which would decrease fuel mileage. It also makes the vehicle unstable on imperfect surfaces. Hit a bump with one wheel and the other wheel pushes more, so the car darts to the side. Pretty similar to running toe out on the front wheels.

Towel city retreads. They sell re-caped camberd tires for roundy round. They sucked in the 80 and still do...

So he designed a tired for overburdened cars...and did anyone ask him what happens when you unload the car once you get to where you were going?

it's an interesting thought, I will give it that

The chart shows his amazing tires pull less peak Gs than the factory tires on the test car even though his had a lower treadwear rating. His tires stopped ONE foot shorter than the factory ones. Just one.

I did it to my '05 Challenge tires. They sucked.
