When changing tires and storing them for a long period, the lifespan will be significantly different depending on whether or not you use a cover to protect against deterioration. Simply place the tire on the spread-out cover, wrap it with the cover, and pull the string to complete the installation. Even women can easily install it by themselves. It also has a handle, and since one cover is used per tire, it is easy to carry. When tires are stored stacked on top of each other, the rubber may start to deteriorate from the overlapping parts, but this is not a concern as they are stored individually. Also, it has a reliable waterproof and dustproof specification. You can use it with peace of mind when storing it outdoors on rainy or snowy days. It can also be used as a cover for the spare tire of RV vehicles. ◇Product Details◇ Applicable vehicles: Can be used for almost all passenger cars, such as light cars, ordinary cars, and RVs.
