I have just installed a set of 4 Michelin Pilot Sport A/S, 235/50-17 tires on standard the standard 17x7 inch rims. Wonder if any of the experts would help me with what the correct pressure should be for these. I am currently running the 33/30 lbs recommended for the OE Bridgestone Turanzas 215/55-17s, but have found that steering effort is up relative to the turanzas. The ride is comfortable in fact, more comfortable at higher speed compared to the turanzas. The reason for this change is that although I have done 36,000 kms ( about 22,000 miles), I live outside of Toronto and the snow traction on the turanzas was just terrible. Rather than invest in a set of 4 dedicated rims and winter tires, I found the pilots to be almost as good in the snow and dry and wet traction is very good.
