Since I have put these tires on the weather in Michigan has been BRUTAL . extreme cold , deep snow , ice .. everything you can think of . Now back to wet right around freezy temp . I am blown away by the performance of these tires & I have had them on various vehicles for 10 + years . Maybe 4 + sets on trucks , SUV's etc . Yes the Audi has AWD but it is not true AWD it is Torsen . Anyway I have a slight slope on my drive maybe 20* . Tonight I stop on the max slope on a frozen patch Complete ice ) to see what happens driving up hill . Zip ... no problem right into the garage .. not even traction control comes on . Then early this week we get 18 in 2 days . Plow guy truck breaks , I back right out turn around & gone , no lie . Get em they are worth every penny & fairly quiet also . I am an engineer in auto for 30 years & completely without bias .
