Simply roll the Clever Lever® under the tire, then lift and pull. To replace a tire, simply push it back in, rotate and tilt for quick alignment with the studs. The HD-24 Clever Lever fits tires from 24" to 48". The Clever Lever® comes in three models that fit everything from light/medium duty pickups to heavy-duty tractors and trailers.
