I have a single cab STX black. I have a 2" leveling kit on the front. Well my decision that I have to make is what wheel size to go with. I currently have 17" OEM wheels on it. I eventually want to blackout my truck but for now I want to get the wheel size down. I don't know if I should get 18" or 20" and I don't want them to look to big for the single cab truck. Any help, advice, or pics would be appreciated.

 

Your choice on the looks, man.

For performance, a smaller rim allows more airdown/sidewall flex for off-road ability. Your tires will also be significantly cheaper the smaller you get. Even the brand new SVT Raptor comes with 17s.
