"Anyone who believes wide tires mean harder riding is mistaken. With the same air pressure as a narrow tire, a wide tire will roll much more easily. “The wider the tire, the lower the rolling resistance. Because a wide tire has a shorter footprint in the driving direction, the tire bounces less and the flattening of the footprint on the road is smaller”, explained Frank Bohle. Result: The tire deforms less, remains “rounder” and rolls more easily."
I'm troubled by: "with the same air pressure as a narrow tire ..." I thought the idea was low pressure tires would flex more taking up shock. Would you run Big Apples with 90-100# of air? If so, why aren't racers doing it?
There is a lot of conversation on this topic throughout the forum but now I noticed a senior guy on here is running Big Apples on his heavily-modded Swift. Other experienced riders are still going the narrower/higher pressure route. I have a DT 8H with a narrower tire on the front than the back which I had taken to be a good thing, i.e. less weight. And I have front suspension to make up the comfort difference. Now I'm wondering if the 2.0 Big Apples really have less rolling resistance, why not put them on and replace the heavier suspension fork, maybe ending up with easier riding and less weight?
