CamberTires

Interesting new design. Has anyone tested these?

It's a crappy design. Camber changes throughout our suspension travel. So if you are hard on the brakes with "camber tires" the contact patch gets much smaller because you're riding on the edge of the tire, this will increase braking distance in an emergency stop.

How would that be any different than a conventional tire?


No doubt that these cambertires are interesting. But after looking at their store, these seem to be stricktly competition only. And with the lack of selection, not legal by SCCA's tire rules.

I also didn't see anything about DOT approvals.

I don't think dynamic camber would like this.

We run negative camber, so cornering or during an emergency stop there is more tire on the ground. It's called camber curve. For "camber tires" to not have that issue, you wouod need suspension that doesn't have any travel. Tires might work on a uneven a-arm suspension, but on a car with struts it's going to be down right dangerous.

And you wouldn't run the same kind of camber with these cambertires? i.e. -1* for a standard tire and -4* for a 3* cambertire.

Would the straightline characteristics not be the same?

Maybe it will be of benefit to the herrafrush crowd if they mount them angled in?

Who is dumb enough to think that would work? Basically what is going to happen is the tallest portion is just going to wear out faster.

Someone should make parallelogram tires for the herrafrush crowd.

How much was he paid to review the camber tires?

They paid him in cambertires.

Here's what I don't understand... in order for the camber tire to help in cornering, then you want the tire to be negative cambered.

However, on their website, they show this (and only this pic) in the tech section:



This is clearly a positive camber. And the description talks about
"Vehicles equipped with more camber from the factory often experience inner tire wear. Using a Camber tire on vehicles like this will increase tire life as well as handling."
By positive cambering the tire, you cancel out the reason for having negative camber. That might help "even out tire wear" for street only straight acceleration/braking but hurts cornering and lateral stability.

Any time something says "improves everything" then that's a red flag. Everything has trade offs. Super sticky R-compound "helps everything" too... at the price of cost, higher required operating temps, and reduced tread wear.

In the video... I'm thinking that this part of the camber tire "technology" had more to do with the grip than the cambering itself:

Our innovation didn't stop with just adding camber, we looked deeper into cornering and
discovered that tire "roll" also caused a loss of handling ability. To compensate for this, we
added in what we call a "rocker" on both the inner and outer corners of the tire tread pattern.
As a tire "rolls" side to side from cornering g-forces, the shelf offers extra contact on the
rolling edge resulting in skid pad results exceeding 1G on a street legal tire!
