Off-road Best 20 Inch Rims typically cost between $150 and $ 2000, depending on the design, manufacture, and supplier. You may need to spend extra money if you buy new off-road rims and wheels from a dealership. The cost of a specific wheel from a dealership is frequently compared to the cost of a set of four aftermarket aluminum rim rims. Most wheel styles with diameters between 18 and 22 inches cost roughly the same and vary relatively little in price.
