I posted earlier about city gas mileage being very low and mistakenly posted "S70" it is V70 GLT. what is the experience of others on city gas mileage and is there anything that will improve it. I get only about 15 mpg in town and sometimes 14 also question re: tires I looked at replacement tires recently that are V-rated and Performance level and that is what is recommended for the car. Someone told me I didn't need V-rated and could do something lower but the Costco tire guy said that getting a lower rated tire would reduce my gas mileage is this true? I mostly drive in town but do a few long trips every year thanks
