My Supremes, at 700X40, and 700X35 are 85 PSI tires. They spin up easily, and roll well at their max pressure of 85. I love the combo of sizes on my bike, with the larger in the rear.

That being said, the roll is remarkably improved at 90-92 PSI.

No improvement over that pressure, and I can feel the resistance at 85 ------- 90-92 is magical for my 190#, and the bikes 42#.

I love these tires so much, that I have three more waiting in the basement, vacuum packed, just because size availability is sometimes a problem.

Just sayin!!!!!!
