I asked two of the LBS that I've had very pleasurable relationships with in my immediate area about this but they gave me two different answers.
I want to replace my tires, currently 26X1.95 mtb, to slicker, thinner ones for more efficiency. My bike is about 85 lbs(35 lbs actual bicycle, 30 lbs batteries-goes on my rear rack, 20 lbs or so for the front hub motor). I am about less than 120 lbs so you can say that I'am comparable to a 180 lbs rider because of the extra weight.
One bike shop said that I should stay with 1.75 or higher, and another said I should be fine, that the weight shouldnt be an issue with generic mtb tires(1.25 all the way to 2.00++) so long as I don't use the thinner road tires.
So which is it? Can I use thinner tires, or should I stick with wider ones?
