Where can I go ( ie:URL ) to find out which tires are most energy efficient ( ie: help you get the best miles?

look for high warranty mileage such as 70,000 miles tire that Michelin,pep boys,and kelly tires offer.

a little hint, tires cant be energy efficient. all you need to do is not put so much foot on the pedal. your tires will last longer. its finding the cheapest NEW tires thats hard. but it usually pays off to buy the more expensive tires.

its in the owner manual , a engineer wrote the book and whats best it is written in the manual stay away from tire shops cause they will sell you anything and make you believe you need them, remember the correct tire size and the correct air pressure is the key to good millage tires will make or break the vehicle

most all radial tires are built with energy efficient materials just keep them inflated to the proper air pressure

I would trust Firestone to give you up front answer they never have done my family wrong
