VERY HAPPY with these. Hot/sunny SoCal desert 24/7 and a few months Tahoe snow/ice. 3 yrs and 50k miles later time for 4 more. Some superficial cracking on the sidewalls and where the tread meets the sidewall but no other problems. I wonder if I had treated them regularly with tire conditioners or if it was kept in a garage or in a shaded parking spot if the cracking would not have occurred. Kept tire pressure per placard on the vehicle. Have also taken them on the beach and on a few fire/very bumpy dirt roads- quite a few very bumpy from the wind making waves in the desert sand/dirt roads/back roads/desert trails too! Tire cables in winter were not a problem either. No slipping, no squealing.
