One of the first things I did was to dump the Hankook runflats and install the Michelin Pilot Sport A/Ss (non-runflats).

Tomorrow I'm off for a good driving vacation with a friend who's driving a Cayman - my Mini needs to be at its best. So I set my tires at the factory-recommended 38/35 and thought I was good to go. Then I called the tire installer to see whether the recommended PSI for conventional tires is different than for runflats. He "calculated" that I should be running 41/41 based on the tire's load rating.

I can understand that conventionals might be different (higher PSI) than runflat tires, but (1) 41 PSI seems to me like a high recommendation and (2) why would all four be the same front/back for conventionals but different front/back for runflats? (I'm talking 17").

In other words, where should I set my new Michelins?

I run ~35 all around in mine daily and on the track. Haven't had any issues and they are wearing evenly.

36 psi all around. 215/45-17 Hankook Ventus Noble 2.great ride,even wear.Love these tires...

38F and 33R works for me with Michelin Pilot Super Sports 215/17s on a 2010 MCS. It sticks like it's on rails and never squeals or chirps. Ride is a nice compromise between handling prowess and comfort. I rotate at every oil change--at 5,000 miles. I love these tires!
