rim-pro - Use these rim protectors when you spoon on your tires to those precious rims..... ESPECIALLY if you have the ultra soft BORRANI rims or want to protect the paint on your mag wheels... These things slip over the rim and the point is to have them in between the tire spoons or levers and your rim while you install or remove the tire. Cheap insurance against damage. If you take your tires in to a shop, it is a good idea to take these in with you and demand that the tech use them while doing the job. PLEASE NOTE - THEY NOW COME IN PACKAGES OF TWO [2] ONLY, I advise you order 2 packages so you will have 4 protectors.
