Raise the vehicle far enough off the ground so there's enough roomfor the spare tire to fit. 6. Remove all the wheel nuts and take off the flat tire. Rust or dirt on the wheel, or on the parts to which it is fastened, can make the wheel nuts become loose after a time. The wheel could come off and cause an accident. When you change a wheel, remove any rust or dirt from the places where thewheel attaches to the vehicle. In an emergency, you can use a cloth or a paper towel to dothis; but be sure to use scraper orwire a brush later, if you need to, to get all the rust or dirt off. 3
