Includes four rim guards. Molding is made of a flexible plastic and comes with 4 3m adhesive packs for installation. Usually, there are three kinds of materials for car rim protectors, which are alloy, rubber and nylon. Among them, the hardness of the alloy material is the strongest, and it is difficult to be damaged by hard objects. Rubber is the softest, it tends to deform or shift in a crash and doesn't protect the rim. Many rim protectors on the market are a pain to install, requiring the wheel to be removed, the tire deflated, or cut yourself. This is very unfriendly to ordinary users.Our products do not require any of the above operations, nor any tools, just simple cleaning and pasting. Falling off is something that all rim protector buyers worry about. We have done a lot of testing and product optimization for this. We redesigned the size and edge shape of the rim protector so that it fits tightly to the rim by its own tension. It is more than 3 times firmer than ordinary rim protectors. If your car has a rash, it can perfectly cover the rash and make the rim look beautiful.
