THX for the help. I put them up to 80 pound figuring that would be in the ball park. By the way, the regular Marathons, not one of the heavier plus tires. I'l see how thes work as they are replacing a great pair of Conti TT2000s. One flat with those tires! great tires!

Oh, and there is nothing on the sidewall of the Marathons that makes sence to me. Something like 3.5 bars to 6.5 bars.

I weigh in at 220, so I'm going to run them at 80 and see how it goes.
