I tried to get a set of the Yokohama YK520's as they appear to be a good high mileage, low rolling resistance tire (at the best price $127/tire). The Goodyear guy did call a lot of distributors but wasn't able to locate a price or any of those tires anywhere around here. Maybe they are new. Goodyear was originally asking $175/tire for the Fortera Triple Tread tires (only ones that come in our size) but I was able to find a price from Discount tire of $158/tire so they have agreed to match that. $62 credit from the old POS Integrity's takes it down under $100 a tire which I guess is acceptable. I've heard that others who got the Fortera's got a bit poorer mileage. Hope that's not the case but I guess we will see.
