1 tires than the ordinary bicycle tires, and the tire pressure can reach 100-200psi (per square inch pounds) above, so the rolling resistance and the mountain bike in the running process is much smaller.

4 tires generally used a very hard material, easy to athletes force. This is not the same as the mountain bike. Because the road bike is a relatively good road in the road above the ride, so do not need to be like the latter, too to consider the issue of vibration absorption.
