I am searching for information on rolling resistance of tires.
The reason for this search is planing a 3,000 mile cross country trip again. That is a fully supported tour at 120 miles / day.
I have done this twice before and learned that tire choice is one important factor. The roads are terrible in places such as split seal and sides of expressways.
My first tour was with 28 mm Conti tires. The second with 23 mm Bontrager and Conti. Each had its problems.
I like to go bigger but have no data to compare rolling resistance. I could buy tires and try them out. Is there a short cut?
BTW, my bike is a Cyclocross CF and can accept any tire. The speeds we are talking about are 100 miles in 5 to 6 hours (flat).
