I tried out my new Windsor Tourist with its 32c tires on one of the local trails.. admittedly, the trail was in pretty bad shap.. lots of ruts from horse traffic and some roots poking out. I was miserable going down the trail with the 32c tires.. my panniers kept bouncing in the back.. the 32c tires were aired to 80PSI.
The bike will accept up to 40c tire width. Will I observe a significant improvement with 40c tires? Will 40c tires also allow for lower air pressure?
