As another track day had come and gone, I started wondering how long my tires were going to hold out... The heat created from lapping and pushing our tires to limit in a racing environment is pretty awesome. It'll raise the tire pressure as much as 10 PSI, and eat away what's left for tread pretty quickly. Here's a shot to show just how hot some tires will get... every little pebble and stone will stick to the tire once it's hot. This is a shot of a friends Nissan 350Z.
