Tyre temperatures - road tyres on track

[EdLeake]

I've been plotting tyre temps across the contact patch trying to level each side out at around 90'C (Bridgestone RE050A) and fighting camber along the way in the pursuit of even temps!

Now my question, is 90'c a good target for a road tyre? I know typically we look for 180-200'F on a cut slick but I'm not sure how that relates to a road tyre (albeit a performance one), perhaps dropping to the lower 80 c's is more appropriate?

Overall temperature (average across width of tread) is a function of vehicle mass, cornering force (lateral G) and power. Suspension tuning and pressure tweaking should get the spread as even as possible but the only way you will lower the overall temperature is to lose weight, drive slower or fit bigger tyres.

It depends how long after your hot laps your taking the reading. I find my S02s go off around 80c but that's at the point of going off, then one cooldown lap.

Having a target temperature isn't going to help your quest without exact, controlled readings.

90 sounds far too hot to me, and if you really mean 'even' i.e. you are aiming for equal temps on both edges of the contact patch you will probably end up with too much camber. There are no absolute rules but typically the optimum setting will result in the outer edge running hotter than the inner edge.
