Guys, I'm hitting the Nordschleife soon and I've only got 2mm of tread left on the front tires (255/35/18 Toyo r888). How long will they last for without a big drop in performance? Will I be able to do two track days (8 runs) on the Ring or should I get new ones?

It's been several years since I last raced on the USDM version of the R888, so take this advice with a grain of salt. If the tire is left with only 2 mm of rubber, the performance of the fronts are likely played out. And if you happen to lock one under braking, a flat spot will likely go right through to the cord. Don't you carry spares for a weekend event like this anyway?

I only have a set of P Zero street tires in case it would rain. I don't have spare semi-slicks.

PS. Found a nice thread that explains what happens with r888 after 4/32" of the thread is gone. I'm close and I don't think 0.4 mm is enough for two track days
