Nether Steve, just surprised at the variance of running temps and pressure. When I got home I had just ran 20 miles. After about an hour of figuringing everthing out the rear tire was still over 100 degrees. After about 3 hours the tires were down in the 80's. The rear tire varied from 55psi down to 39 psi. So the question is do I set the tires cold temp to 41 still?
