If you're running the "ideal" amount of camber for your setup, should there be any temperature gradient across the tire from inside to outside?

At Roebling this weekend my outside edge was up to ~38 degrees hotter than the inside edge. I could obviously benefit from more camber, I knew that before I checked temps.

Are even temps inside to outside the goal? Is say a 5-10 degree gradient a reasonable compromise?

 

Your inside temps should be around 20% hotter than the outside because the tire spends more time on the straights than the corners. Naturally, the inside will retain more heat than the outside section of the tire.

 

How did you come by the 20% number? Seems like that would be too hot on the inside edge.

I was at roebling this past weekend, and I'm pretty sure I spend more time with the wheel turned than straight. I can review video to confirm.

Furthermore, the amount of heat generated per unit of time under cornering would be much greater for the front tires than on the straight.

 

Yes, but consider this, accel, braking and anything in a straight line heats the inside... also turning heats the inside of the inside tires. I agree that 20% sounds too high, im thinking more like 5-10%

Yup, hotter on the inside by xx degrees. %age temperature is meaningless on a non-absolute scale!

Consider that while cornering with optimized camber for cornering, you should be heating the tire evenly, while on the straights you'll be heating the inside. Also, speed in and of itself, aside from braking, accelerating, and cornering puts heat in the tires, and when you're going fastest, inputting the most heat, you're in a straight line.

 

Thanks for the link.

From the article... "If the outside temperature is consistently hotter (by more than 10 F) than the inside, try dialing in a bit more negative camber."

Therefore if the inside edge is no more than 10 degrees COOLER than the outside...
