For example, let’s look at 11R22. In this example, the information includes: 11 = Section width in inches. R = Radial Tire. Rim diameter and rim type. The 295/75R22. R22.So, a 10R22. R22. This might not sound like a huge leap, but that extra inch can translate to a wider contact patch with the road.
Do XL tyres use more fuel?
Increased fuel consumption – XL tyres tend to be heavier, which can slightly reduce fuel efficiency as the engine has to work harder to compensate for the added weight. Larger wheels = 4-10% decrease in fuel efficiency due to increased weight and rolling resistance. Smaller wheels = better MPG, less strain on engine and drivetrain.
