This is a quote from Rob that I pulled from another thread.
"Frankly, I want my tires to be ready for anything that gets thrown their way without having to play with pressures, so I run my PR2's at 26 to 29 front and 28 to 31 rear all the time.. At those pressures and a combination of Malibu twisties and 100 mile a day commute they lasted 10,000 miles rear and over 12,000 miles front. That's a low average.
Given the Michelin's no warmup, excellent manners, unequalled wet traction (well, exclusive of racing full wets which would last all of 5 miles in the dry), and longevity, they will be my tires of choice for the foreseeable future."
I only have 500 miles on mine so I can not attest to longevity, but after reading Rob's post I have set my pressures at 32/36 and Hope to hit 15,000 miles. I am tempted to drop the rear to 34, but my 9'er sees way too many highway miles.
Don't steal. The government hates competition.
