Haven't been in the wet yet. I live in Phoenix and its been over 100F since April. I had to do an emergency stop when a jackass jaywalked in front of traffic. The front T63 held great but the 908 rear locked up quickly. I'm going to try a more 50/50 tire in the rear when the 908 wears out and keep the T63 front. I'm going with the Karoo 3 in size 140/80-18.
