18 Inch Wheels FAQs

01

Can I use my existing tires with new 18 inch alloy wheels?

You will need to purchase tires that are specifically designed for 18 inch wheels. Using the correct tire size is crucial for safety and performance. Avon, Dunlop, Metzeler, Michelin, and Shinko brands all carry tires for 18 inch wheels.

02

Do 18 inch wheels affect fuel efficiency?

The effect on fuel efficiency is minimal. Larger wheels can slightly increase rolling resistance and weight, which affects fuel consumption, but the difference is negligible. We doubt you’ll notice much difference in fuel efficiency.
