Wheel tutorial: Lasso the rim w/ the polygonal lasso or the elliptical marquee tool. (Zoom in A LOT and lasso it perfectly, not sloppily) Then hit ctrl+t and start playing with it by making it bigger, rotating it, skewing it, changing perspective, etc. Finally, paste the rim onto the car you're chopping and cut away the excess w/ the poly lasso tool. If it's hard to tell what you have to cut away, zoom in and put the rim's opacity on like 5%. Hope that helps dood.
