I just installed a set of 215/35/18's, new to the Mini world so, what would be the recommended pressure you guys run for daily driving?
Thanks.

check the door jam for the recommended tire pressures for your wheel size.

37 psi front and back or a little higher cold temperature is OK

I"m running 215/40-18's (Hankook Ventus V12's) on my full JCW cabriolet and I run 38 front, 36 rear. And based on the wear patterns after I drive it hard, I might be able to lower the rears maybe a 1 to 2 lbs. But 38 in the front seems to work very well. I also ran that pressure with the runflats that used to be on it.

Remember, Mini recommends 36 at both ends for the low profile 18" tires (205/40-18's), but I think that since there's more weight on the front, that a little more pressure there helps.

If you look very closely at your tread where it wraps around the side of the tire just a bit, you'll find some small triangles. These, I've been told by some racing shops, are indicators that help you set up your tire pressure properly. In hard cornering, you should be scrubbing the tire right up to the mark but not beyond. If you're too far away, you're either not cornering hard enough or your tire pressure is too high. If you're going beyond the mark, your tire pressure is too low.

With your even lower profile tires, I wouldn't go any less than 38 front, 36 rear. Maybe a bit higher.

Thank you guys, i got them from Tire rack with wheels and they where all set at 35psi, i will play around a little bit to see what it likes.
