Cars Car Tuner, tyres question

[sawier]

Hello everyone, I made a drift tune for one of my cars(the skoda octavia cup from here). I Think I have it dialed pretty good, it drifts nicely. The only problem is when the tyres get warm its like they are made of ice. I can literally slide it without even pressing accelerator, just turn the wheel and it goes. I tried editing the wear and thermal but it makes almost no difference and I don't want to lose the realism and just put same traction value for every temperature. Any ideas what can I change?
