This sale is really unreal: best prices I have seen for some high-quality models and sizes, such as Altimax RT43 and Cooper CS5. (A Cooper manufacturer's discount was just added today, I think.)
Check out the RT43. With all discounts applied, you can get a set in 175/70R13 for $75; or in 175/70R14 for $79 (!) That one tempts me, based on the rave reviews, even though I won't need tires for more than a year. Just the thought of getting high-quality tires for $35 a corner, installed, like it's 1990 again, when I was young....
Prices on the CS5 are almost as good. I could buy a set for my friend's '08 Corolla CE for $105. Outrageous. Almost makes a fella wish he needed tires.
