tire pressure for 17's?
hey guys,
i was wondering what would be the best pressure for my tires. i have 215/45 17's nitto 450's. the max pressure is 44 psi.
i'm more concerned with fuel efficiency but at the same time not popping the tire. i know you calculate between 85 and 90 percent of max pressure.
i've taken my car up to 148 mph once on a whim. i wasn't at that speed for more than maybe a minute. if i inflate my tires to 38, and ever got up to top speed again would my tires pop?
i'm debating between 36, 37 and 38 psi.
thanks,
peter.
