Will 18 wheels fit a 2003 Jeep Wrangler?

18-inch wheels will not fit on a 2003 Jeep Wrangler without modifications. The stock wheel size for the 2003 Wrangler is 16 inches, and the maximum recommended tire size is 32 inches. Installing larger wheels would require modifications such as a suspension lift, longer lug nuts, and possibly custom wheel spacers to ensure proper fitment and avoid rubbing. It is important to properly match wheel size and tire size to the vehicle's specifications to maintain safety, performance, and legal compliance.
