What is the extra effort needed to ride on 2inch tyres instead of 1 1/4 inch

johnk · 08-23-2010, 07:09 AM

Has anyone any information on the rolling resistance of tyres on tarmac. I'm trying to find out how much longer my Hybrid with 2 inch tyres would take to do an hours ride on my road bike with 1 1/4 inch tyres. They are both about the same weight. I expect most effort used is overcoming wind resistance.
Thanks
