Tyre Pressures

[RobP]

Hello to all on New Mini forum! I've just got a 06 plate Cooper S for my wife and having picked it up from the main stealer found that that pressures were set at 28psi front and 35 psi rear. I reset them at 35 psi all round as per instructions on door post for 17in run-flats with 2 peeps up. This seems like a good place to start but what is the experience that you guys and gals have had with pressures? Search facility doesn't turn up much in the last 6 months. TBH I'm looking more for ride comfort and economy rather than out and out grip/feel/cornering ability.
Thoroughly enjoyed test-driving the car down some country lanes. Cracking drive
