Message	I broke down and got a set of 275/35-18 and 245/40-18 Michelin Pilot Super Sports last week. I figured with winter coming up I shouldn't risk going with R compounds or drag radials if I'm going to be driving the Z to work at all on chilly mornings. Anyway, I think I've got about 32-33 psig in all 4 corners, and if I push it a bit in a corner the Z feels mushy and floaty, almost like I'm on balloons. What sort of pressures should I be running? Tires are much wider and much less sidewall than stock, so I don't think the OEM pressures are valid. Thanks, Mike --------------------------------------------------------
