Which is More Fuel-Efficient: 175 or 185 Tires

[StEvan]

Definitely the former is more fuel-efficient. The 175 tires have a smaller contact patch, making them slightly more fuel-efficient than the 185 tires. The differences between 175 and 185 tires are as follows: 1. Fuel efficiency: 175 tires have a relatively smaller contact area with the ground, resulting in less friction and thus better fuel economy. City bicycles typically use narrow tires because road conditions are good and frequent acceleration or deceleration is unnecessary, making them more energy-efficient. 2. Safety performance: 185 tires have a larger tread than 175 tires. The larger the tread, the better the driving safety. Using wider tires on cars can improve safety, as the larger contact area with the ground during braking allows for more complete transmission of braking force to the road, thereby shortening the braking distance.
