tommorow I will be going 150 miles all express way miles and I wanted to know what would be the optimal tire pressure for best economy on the highway ?

I'm running bfgoodrich g-force kd 205/50/15 at 35psi right now and wanted to know if I could go higher for better highway results ?
What is the highest pressure I could run safely ?

thanks

 

Stay with the recommended pressure for the tires. While increasing pressure may yield a mile or two per gallon, too much pressure will make for a harsher ride and wear the centers of the tread. 35 sounds about the best for overall wear and ride, unless the manufacturer says otherwise. Your right foot will make the biggest difference.

 

yeah, leave em be, 32-35 usually give you the best contact patch and least rolling resistance...if you are really wanting good gas mileage, rent a lil gas sipper for $19 a day.
