I had my G5 out yesterday with the temps at 40F and there was no traction anywhere/any gear. The Corsa's are a great warm weather tire, but I noticed that the difference from 80F to 50F was like being on a different tire. We know that temperature affects traction, however, these tires exacerbate that difference. Tom is one of the best drivers we have in the racing community, he does not typically make mistakes, hope he is OK.
