Please help with some advice. 2010 Gen 3 prius averaging 18-20k yr highway and city driving. New car came with Yokohama AVID S33D P195/65R15 895 Tires at 40k now at 4/32'nds and it is time for new ones. We get our fair share of winter snow, but then again this winter I did not need my shovel once. Any ideas? Dealer suggests(because they have on hand): Goodyear Eagle L52 Goodyear Integrity Bridgestone Ecopia Bridgestone Insignia What tires can I get that could be better than what I have, offer longer life, be low resistance and possibly improve mpg? Thanks y'all-my head hurts from reading in circles about this and getting no where!
