Lost the rear like I was on ice on a left-hander last track day. Noticed the tire wear has a distinctly different looking (much smoother) area on the left edge after cooling down. Is this from over-heating/over-working a non-race tire? Is this what it means when people say q3s can get greasy when hot? Pressures were 30/29 cold. gsxr 600. pointy end of intermediate group. About 85 deg out. track is mostly lefts. Fifth out of six sessions. thanks.
I was six seconds off race pace, but you're right, they weren't showing wear like I've seen with slicks. I just thought it was odd to have a stripe of different texture on the most worked part of the tire and didn't know what might cause it.
I'd say you got more lean angle as your confidence grew throughout the day and ended up on that ridge that developed from earlier riding, narrowing your contact patch from a melon to a banana.
You mentioned the left edge in the first post. The edge is not the most worked part of the tire. The drive portion is the most worked. The smooth band on the left edge is probably from you not using it. I doubt the tires had anything to do w your crash. Without video, we'll never know.
Given how smooth and minimal the wear is, I seriously doubt this. The profile prob hasn't changed at all. On top of that, tires flex. A tiny change in the profile shouldn't reduce the contact patch enough for an intermediate group rider to lack grip.
I'll be on Ntecs with warmers next time out. Gopro went straight into a hay bale and lost the footage but here's a pic in the same corner a couple laps previous. I know that doesn't tell much. Thanks for the things to think about guys.
I used Q3's on a s1000rr and I ran 33/31 and it wore like I needed more air. I'm at the pointy end of advanced on a street bike. Used the Pirelli Sp's on Saturday and a MUCH better tire. Didn't have the confidence with the Q3's.
