i never really pumped a tire over 118 ... im only 138 pounds though. i do feel a difference in getting worked over. i rode over some cobble stones once in a race for a while, needeless to say after the race it was not pretty .

This is just my opinion - but I think rough pavement is rough pavement. It feels bumpy no matter what your tire pressure is. Plus, if you lowered your tire pressure, wouldn't you also increase your chances of getting a pinch flat?

We had some rough patches at a tri this weekend. A good friend suggested backing off on the PSI a bit - some studies have shown that the more you bounce off the road, the less distance you get per rotation on your tire ('cause you only move forward when your tire is in contact with the road). I think it's a very fine line that requires a bit of trial and error, but I can see the point in going down about 15 PSI for a rough road. It also jostles you around a bit less, and that's a good thing in my book.

All,
Rode my first International Distance Duo this last weekend, and with the tubulars, I ran the tire pressure up to 150psi. The Tufo's are rated from 115-175, so I was within the tire pressure rating.
On the ride, I hit several rough sections of pavement, and I thought I was going to leave body parts behind on the road. The wheels were rolling just fine, but some pavement sections seemed to really pound me.
Should I lower the pressure down to 125 or so and increase the rolling resistance? I haven't tried riding the tires at the max psi, and in a way, I'm afraid to.
