Tire width is the most important in road cycling. Usually, cyclists on the road mostly use tight tires (23 mm) or used smaller ones. Usually, these tires are quite light, and therefore they work fast. Now the choice of people has become quite different. Manufacturers are telling bicyclists to use wide tires (28 mm or larger). Now between the claims that they offer the standard of low rolling resistance and a more comfortable ride. Indoor Roller Testing Frist Part Tire Width Easy to test. Take two sets of tires of different widths and ride at a fixed speed for a fixed time. Then we record the power needed to maintain this pace. All these things, such as a motorcycle, wheelset, tire type, and riding position, will be the same in each race as the tire will be pressure, 26mm, and 30mm, while both tires are flown to 90psi / 6.2 bar. If the width of one tire is faster than the other, what will need less power output to maintain the target? The target speed was 40 km per hour, and the interval was 5 minutes. It would be best to assume that this test is not like a ride in the real world because the rollers' level is smoother than any road.
