What Advantage Do 20-Inch Wheels Have Over 18-Inch? – In the automotive world there is a concept known as “plus sizing” of wheels. The concept is basic, if you have a vehicle with 18-inch wheels, plus one would be a 19-inch wheel and plus two would be 20 inches. Moving to a 20-inch wheel from 18 inches can provide several advantages.
Visual Appeal – A 20-inch wheel has less tire sidewall and more wheel showing than an 18-inch wheel, which can be more visually appealing.
Handling – When swapping from an 18-inch wheel to a 20-inch, a tire with a smaller sidewall will be required. This smaller sidewall will provide your vehicle with improved handling characteristics but will also come at the cost of a harsher ride.
