So i know that If the center of the tire is hotter then the sides you should start by lowering pressure.
I know that if the sides are running hotter than the center that you should start by increasing pressure.
What should i do if the inner portion is hotter then the middle and outside, or if the outer is hotter then the middle and inner side of the tires ?
Also does it matter if its the front or rear tire, or if the drivetrain is RWD, FWD or AWD?
Thanks
In my mind (based off the real world) that would likely be due to camber (and potentially toe) moreso than tyre pressure
When I see this, I try more negative camber and/or stiffer suspension to reduce body-roll.
When I see it’s more prevalent in the front or rear, I interpret that as an indicator of where adjustments should be made to better balance the car’s response to lateral weight transfer at that end of the car.
So i definitely get higher inner temps more often then higher outer temps so what would you adjust first? Less negative camber?
1st don’t look at tyre temps on straights at all,
Only look at temps under full load (for eg on 1st corner of maple).
If outer temps are higher u need to increase camber, if inner temps are higher u need to decrease camber, that’s all.
I usually run 0/0 or 0/-0.1 toe, anything else just makes car handle weird.
Is that the primary metric for setting camber i should be focusing on?
Thanks everyone btw.
pretty much. Most default camber values are too much. I’m generally around -0.6 to -2.0 range. Wider tires need less camber. a good general starting point is Front -1.5/ rear -1.0
Simple way to find tyre pressure:
Take a track with a long straight
Put camber to 0° front and rear
Go on the straight and do some acceleration and braking without cornering
Set the pressure to have all three values the same Temperature
Once you get your temps right, you found your pressure.
