Currently I have the set at 32/35 seems about right to me. What have you set your tire pressure at.

That 35/41 was the same as my 2002 Dodge Dakota PU which never felt right.
I finally settled on 40 psi cold or 44 psi hot all around either fully loaded or unloaded.
So I took my X1 s28i to HPR raceway and tried different pressures using a laser temp gun to even the temp across tire.
I also measured the temps while driving at 75 on a hot day.
I settled on 38 cold (80 deg f ambient) or 42 hot (driven at 75 mph) on all 4 tires.
I have the summer performance Pirelli P7's, and they are very good except they seem bouncy at any pressure.
In a few years I'll have a light weight tire like Continental DW.
