I envision the inside tread deeper than the outside with the tire mold diameter equally less from inside to out.

That is an interesting idea, but how about making the outside of the tread deeper, so that it compensates for the negative camber?

I think those are both good ideas and would give you much better wear with negative camber. But wouldn't it also depend on the tire pressure you are running? I bet the wear is much better is you stick to factory pressures.

The old BF Goodrich R1 tires were such a tire...Designed for camber challenged cars where the outer sidewall was stiffer than the inside one....Used to run these on my old Mustang before it got camber plates....

Those were great tires! I still have a couple sets of them....wish they were still made.

When the insides start to wear, mount them on opposite sides.

993inNC

????? why? Arent they still worn on the inside? And now they're not directional any more......right?

Radar

Left to right and vice versa, they would be.

993inNC

No....., wouldn't front to back keep them directional? side to side turns them the oposite "direction"....?

Radar

If you dismount the tire and mount it back on the opposite side keeping the same direction, they would remain pointing the same way.

Well, okay you got me there, but now you'll be running some serious positive camber won't you? Most race cars run a good 2-3 or better degrees of negative camber, not to mention the 1/2 degree built into the tire. If you put the wear out......wouldn't even want to think of what that would do to the handeling characteristics of the car.

What we always did with them is put the worse worn tires where ever the camber requirements were less, this wears the outside down more and evens the wear out.

I've done it regularly with track tires but never with street tires. The concept is the same. Negative camber increases the wear on the inside tread of the tire. By remounting the tire to the outside of the wheel and bolting it to the opposite side of the car the worn part of the tire not on the outside will wear slower than the inside. It should work as well on street tires.

Directional tires are for shedding water....the tread pattern (or what's left of it if it is a track tire) will be of little-to-no consequence on a dry track. FWIW, Kumho allows remounting tires in-to-out (inside-out) to even out tread wear...no big deal at all. Not only can I get a few more weekends out of them, but I feel no ill handling characteristics other than the tires' general decrease in grip from wear/heat cycling anyway. Of course, if your camber is set up properly for your driving, you won't have to do this since your tires will be wearing evenly across the tread. But for a "compromise" car, it's just one way to get more for your tire dollar ...if you're not chasing after that last 10th, anyway
