MPSS Pressure?
Hello All,
Just had Michelin's put on all four corners and couldn't be happier! Was wondering what some of you with more time on these found to be the best pressure. Any input is welcome.

I don't have mine yet, they should be getting ordered soon, but I figured I'd start out using the stock 32psi and see how that works.

Thanks for the reply. 32PSI is what I'm currently running, just wondered if there was a better PSI.

Running stock size fronts at 32 cold. Running 315 rears at 29/30 cold. I had them at 32 cold to start, but found the center of the tire was wearing faster than the outside. MPSS all 4 corners

I run 36 on all four. You need higher pressure for higher speeds.
From the Michelin web site for the PSS: For speeds over 160km/h (100 mph), load and inflation must be adjusted according to the table below. (Y)-Speed Rated Sizes: Maximum Speed (mph) 118 124 130 136 143 149 155 161 168 174 180 186 Inflation Increase (psi) 0 0 0 0 1.5 3 4.5 6 7.5 7.5 7.5 7.5 Load Capacity (% of max) 100 100 100 100 100 100 100 100 100 95 90 85 For speeds above 186 mph (300 kph), consult your vehicle manufacturer and tire dealer
