After 10,000+ miles on my Saturn SL2 I am ready to leave an informed review:
My old tires were Fuzion HRi 195/60HR15, roughly the same price range. They lasted me 50,000 miles. I recorded 33.3mpg over 20,000 miles. The new tires are averaging 29.4mpg over 10,000 miles, no other changes to the car and the drop happened the tank after I switched.
What that means is that with these tires I have paid $160 more in gas so far than I would have with my old tires ($4/Gal). By the time I reach 50,000 miles I could have bought 2.5 extra sets of the other tires, which handled and rode significantly better.
Sorry Continental, you failed.
