Camber Tires - built in 2°

[MJ23FE]

According to the picture in the link provided the tires have different height sidewalls and aren't actually angled like that.



What I don't understand is why you wouldn't just leave the suspension at 0 degrees and put the short sidewall on the outside.


NASCAR uses square tires like everyone else.
Matt, I don't understand what you mean when you say that they aren't actually angled like that. The different heights of the sidewalls make the angle that you see.

If you left the suspension at 0° and put the short sidewalls on the outside you would have positive camber.

Since one sidewall is shorter than the other that means the tread itself is angled 2 degrees, which is what would happen if you put 2 degrees of camber into the suspension with a square tire.

I think the negative camber is to offset the camber of the tire and make the tire sit flat on the ground all the time. A lot of guys run -2.5° of camber in the front anyways, right, so what would happen if you took this tire and ran the suspension at, say, -5° of camber.

The interesting side effect to this tire that is kinda neat is that it eats up the road a little nicer while cruising. Totally not what I would have thought of but it makes 100% perfect sense. Instead of the force of the road traveling straight up the sidewall, it is at an angle, so the sidewalls sorta flex like an offset spring and eat some of the directional force.

Running 0* front camber would do the same thing. The way I see it, using this tire as stated and pictured, is pointless. Negative camber is all about gaining maximum tire contact patch when the car is leaned over, running a tire flat on the ground while going straight will pull the inner edge up in a corner while a car running negative camber with traditional tires will have a larger contact patch on the road.

I agree completely. 0 degrees is 0 degrees, regardless of what the wheel is doing. If the tire is flat when it's static then it's still going to want to roll in a corner, and a taller outside sidewall is only going to make that worse.

Correct. We're on the same page regarding that.

I would think you'd get -2° front camber if you did that, no?

If you left the suspension at 0°, wouldn't there be a ton of stress on the hub?

Also, wouldn't that mess up suspension geometry and such since your suspension components would be at positive camber, but your tires would be at their static camber?

Yes, Matt. I realize the actual structure and composition of the tire, and although I have many talents, drawing the concept using an ASCII character set isn't a strong point. :jackoff:

I think there may be some benefits to having the wheel 2degrees more tipped in. It might be important to note, that like they said, you would have to adjust your alignment for those tires. I would guess they were assuming the suspension and tire roll in about 1 degree so with this tire you could get the geometric benefits of having the hub -3degrees to the ground but only the wear of -1degree of camber...
