Re: Ideal tire pressure for gas milage & wear ?
go old school.....
get some white shoe polish ( you know the one with the little sponge on the top) put somo on the sidewall and tread about an inch or so each way...take it to work or what ever....for every 1/4" the polish is on the side wall add 3 lbs and for every 1/4" of tread showing take out 3 lbs...do it a couple time till you get it just right.....I WILL BUY THE NEXT SET ( ok maybe not but I'm that confident) of tires if you have no other issues in your front end and if those tires dont wear flat and you get the best milage...this works on ALL cars and trucks....the door tags are for MAX load of the vech...but I don't know anyone who has 4,5,6, people and a trunk full all the time...most people I know its just them and a weekly trip to the grocery store
Over or under inflating tire will give better mileage UNTIL the center/outsides are worn then all you have is a 1/2 bald tire...rolling resitance ( tread design and hardness of compound) is the biggest factor on milage ...this is the reason that you see ALOT of big trucks going to Super singles instead of the old style duals...10% less rolling resitance
