Every driver is likely familiar with this mnemonic: from O to O. This means that summer tires are used from Easter to October, and winter tires are mounted for the rest of the year until the next Easter. But where to store the car tires? They should take up as little space as possible in the garage and be stored safely. The solution is the cartrend wheel tree. It easily accommodates four car tires with rims up to a width of 225 mm. The wheel tree can be assembled with just a few steps and meets all the requirements necessary for gentle storage. Each tire is stored with its rim on a plastic bearing, ensuring that neither the rims nor the tires come into direct contact with each other. Despite being stored for months at varying temperatures, no condensation forms, which could promote corrosion. Since each tire is stored individually, there is also no risk of deformation. Additionally, the wheel tree serves as an assembly aid, as the wheels can no longer get mixed up. For example, a cross swap of the wheels can be performed to prevent wear patterns such as sawtooth formation. This way, the rolling comfort of the tires is maintained for a longer period. The wheel tree is completely freestanding and can be quickly and easily assembled using a plug-in system. In the basement or garage, there are no more tripping hazards from improperly stored car tires, and cleaning the storage area becomes much easier with the neatly stacked wheels arranged horizontally.
