For sure, the size of the wheel matters. It changes a lot of things. Like 17 inch or smaller wheel size will have better mileage than 30 inch alloy rims. Not only mileage, but it also affects the speed and performance of the vehicle. A 24-inch wheel will be a lot heavier than a 17-inch wheel, which means cars or trucks must carry more pounds, and the engine needs more power. Well, of course, bigger wheels give your ride some good looks and stability as well. But again, one should do thorough research if their car can carry bigger and heavier wheels
