The tire carrier helps secure your spare tire under the vehicle. These spare tire hoists or winches are cranked down when needed, often using a special tool provided with your vehicle. Over time, your spare tire hoist may corrode or jam due to environmental factors and road debris. If you are unable to use your tire carrier, it should be replaced right away so you will always have access to your spare tire. At O'Reilly Auto Parts, we stock universal spare tire carriers and can help you find the right one for your vehicle.
