What tire pressure do you run?
I have a set of Mich sport cups and I want to make sure that I have the right pressure. (max on tire is 51)

What type of tires are you running becuase that can help the answer - size and brand here.

What usually works out is to have 38-42psi HOT. I would start at 35psi (cold) all around (not knowing anything specific of your set up). I would also "chalk" the tire where the shoulder meets the tread to see how much the tire is "rolling over". If it rolls over too much, keep adding air. And check your pressures during your runs... as they should "gain" pressure if you are using them correctly
