My front passenger's side tire blew out a few months ago and I've been running on a spare since then. I'm going to get a set of new shoes for my car when I get my tax return. I could get the really expensive low rolling resistance tires, but I read that the gas savings doesn't make up for the added price of the tires. Do you think getting the cheapest 195/65/R15 tires out there is what would be most economical, or do you think something midrange price with better(but not great) rolling resistance would be the most economical over the life of the tires in tire price vs gas savings.
