16.5 in rims only fit the that size tire 17 or 16 will not work with them you can find different tires on eBay for the 16.5 rim size and tire anywhere between a 25 inch tall tire to a 54 in tall tire but the only downside of running the 16.5s or are they charge you an extra $100 per tire now on top of the price of the tire I hope that helps
