Recreational Cyclocross and Gravelbiking This has to be the most physically intense sport ever invented. It's high speed bicycle racing on a short off road course or riding the off pavement rides on gravel like :The Dirty Kanza". We also have a dedicated Racing forum for the Cyclocross Hard Core Racers.

Tire Pressure?

Hi, my street tires are rated 130psi max. Do I want to fill it that high?

The PSI rating for the tire itself isn't the full story either. Your rim's will have PSI rating as well. Generally speaking, you don't run your tires at the max PSI rating.

Since you asked this in the cyclocross forum, I'm guessing your asking what PSI your cyclocross tires should be? I run 40 -55 PSI depending on the race course and weather. These are for 32 - 35 mm clinchers (Ritchey Crossmax's and Maxxix MiMo's.)

As for road, I run 23 mm clinchers at 115 - 120 PSI for racing (Mich Pro2Race) and 100 PSI on 25 mm clinchers at 100 PSI for training (Conti Gatorskins.)

I would start with 75 PSI and take it from there. Go up to 85 or down to 60 as comfort, performance, and/or tire wear dictates.
