Do wider tires ride better?

Wider tires have an increased risk of hydroplaning on slippery or wet surfaces, but they generally provide better grip for dry surfaces. Narrow tires will offer better traction in slippery conditions, but they are generally better for lighter vehicles such as hybrids or electric cars.

Do wider tires go faster?

Yes. This is because, at the equal pressure, the casing tension of the wider tyre is higher and the contact patch is shorter and wider. The first of these factors means less energy is lost to casing flex, and the second reduces rolling resistance because the shorter, wider contact patch reduces frictional losses.

Do wider tires look better?

Narrow tires are cheaper but wider ones look better

The tire width will affect their price and several other characteristics, such as grip, noise level, driving comfort, and appearance. Replacing narrow tires with wider ones will usually increase rolling resistance and, therefore, slightly increase fuel consumption.

Do wider tires use more gas?

Tire Size. Larger tires decrease your fuel economy because they are heavier, while smaller tires increase fuel efficiency.
