It also depends on your driving style. If you pitch the car into the corners the tire's will heat up quicker
when i pitch and slide, my tires wear so much faster. in the past few months, i've adjusted my driving style to not be as agressive, and it's actually made me feel more in control.
of course, if you've gotta chase 'em down - sometimes pitchin' and slidin' is the only way to go!
