True owenership costs
Echoing the ballpark figures already in this thread... . The true costs should factor in your mileage covered. The "high" purchase costs at the outset are more than offset by the high mileage, resulting in a major saving over multiple sets of 16 inch rubber.
I took a hit on the Yokohama TY303s but they deliver the goods and I am confident that I'll get well over 100k miles on each tire - right now they've covered just over 20k miles and still look brand new.
