I run my pressure in the mid 30s and have not had any cupping, I even got really great wear out of the original Lasertech that was on the front.I forget exactly but I got around 15,000 out of it I think and it was bald all the way across with just a hint of the tread left in the center.

I learned all I need to know about life by killing smart people and eating their brains.
Eat right ,Exercise ,Stay fit, Die Anyway!
