As are most of us, I'm trying everything I can to wring the most mileage out of a gallon of gas. I know tire pressure is important (and about the cheapest "fix") to getting good mileage. But what's the right pressure?
I'm running the tires that were on the truck when bought used from the dealer - El Dorado XTR Sport - P255 70R16. The little web research I've done on these indicates they are probably made by Cooper Tire and sold through Walmart. (Figures that the dealer probably put something cheap on to sell the vehicle). They seem to be getting the job done though.
I'll be darned if I can find anything printed on the tires themselves about proper pressure. I did note a little decal however inside my fuel filler door that shows for this sized tire (which must be the "stock" size for an ST??), that 30 psi for the fronts and 35 psi for the rears is recommended. That seems a little high to me.
So... what is the "proper pressure" for these tires to get the best fuel economy, ride, and tire wear?
