1. cat pictures are silly
2. "Rubbings racing" is a quote from Days of Thunder, the movie
3. go get a rolling pin from Crate and Barrel, etc
4. a rolling pin for cooking is better than a baseball bat, because the rolling pin is softer and less likely to crack the paint at the contact points
5. mount the wheels and tires
6. put the pin in between the tire and the inner fender and roll and push at the same time
7. go slow and you can roll them great
8. your objective is to push the inner lip up, from a horizontal angle to like an 80degree angle

p.s. BMW and no 20's? what are you unemployed? rolling on teenage rims is silly
