the nut in middle is not removed to take tire/wheel off.....wheel is just stuck...i had a flat on a 94 toyota...removed all nuts and couldn't get it off...even put it on the ground and drove a bit with the nuts off it...then hammered it and used a pry bar....finally called for a wrecker/flat bed and the shop guy used a freaking torch to heat it and hit it with a 15 pound sledge hammer to get it to pop off...I never saw anything like it...good luck
