You probably drive your Toyota FJ Cruiser everywhere, through all sorts of weather, fair to bad. The roads you drive on are full of hazards, too, from dirt and debris to nails and broken glass. So, you've probably seen your share of flat tires as well, from partial deflations to blowouts. Having a spare tire on your trunk hood in these situations is critical. Even better if you can keep that tire in the best possible condition, for as long as possible, whether you're traveling, parked outdoors, or your FJ Cruiser is in storage. The way to do that is by storing it in a genuine Toyota tire cover. They help keep out moisture, for one, which helps keep your rims from rusting. They also keep dirt from collecting on tire parts, not to mention that they keep UV light from cracking your tire's sidewall, which can lead to a slow leak or even tire failure. They even stave off oxidation, which can cause premature tire drying and cracks. In short, protecting a spare tire with a factory tire cover can mean savings over time, as changing tires frequently from all-season or summer tires to winter or snow tires is already costly. So, what size spare tire cover do you need? That depends on what size tires your Toyota FJ Cruiser has. OEM tire covers fit best either way. After all, they're made by Toyota to match your Toyota FJ Cruiser tires' diameters specifically. You can order yours right from our auto parts counter. Buy now and we'll ship immediately.
