Preparation
Park the vehicle on a level, solid surface. Engage the parking brake and place wheel chocks on the opposite end of the vehicle from where you're working. Inspect the new tire to confirm it's the correct size (1200 20) and free from damage before beginning.
Loosen Lug Nuts
Before lifting the vehicle, use the lug wrench to break the initial tension on the lug nuts by turning them counterclockwise. Don't remove them completely at this stage—just loosen them enough to make removal easier once the tire is off the ground.
Position the Jack
Locate the designated jacking point on your vehicle's frame or axle. Position the hydraulic jack under this point and slowly raise the vehicle until the tire is approximately 2-3 inches off the ground. Place jack stands under secure frame points for additional safety.

Completely remove the lug nuts, storing them safely where they won't get lost or dirty. Carefully pull the wheel straight off the hub, being mindful of the significant weight of 1200 20 tires. You may need assistance for this step due to the tire's size and weight.
Clean the Mounting Surface
Use a wire brush to clean the wheel hub surface, removing any rust, dirt, or corrosion. Check for damage to studs or mounting surfaces. Apply a thin layer of anti-seize compound to the hub (not the studs) if working in areas prone to corrosion.
Mount the New Tire
Carefully lift and align the new 1200 20 tire with the wheel studs. Push it straight onto the hub until it sits flush against the mounting surface. This may require significant effort due to the tire's weight.
Install and Tighten Lug Nuts
Hand-thread the lug nuts onto the studs, ensuring they turn freely. Once all nuts are in place, begin tightening in a star or cross pattern (not in circular sequence) using the lug wrench. This ensures even seating of the wheel.
Lower the Vehicle
Carefully remove the jack stands and lower the vehicle until the tire contacts the ground but isn't bearing full weight. At this stage, use the torque wrench to tighten the lug nuts to the manufacturer's specifications (typically 450-500 ft-lbs for 1200 20 applications).
Final Torque and Pressure Check
Lower the vehicle completely and remove the jack. Perform a final torque check on all lug nuts following the cross pattern. Use your tire pressure gauge to verify the tire is inflated to the recommended 120 psi (or manufacturer's specification).
Disposal and Follow-up
Take the old tire to an appropriate recycling facility. Many tire shops will accept used tires for a small fee. Re-check the lug nut torque after 50-100 miles of driving, as settling may occur during initial use.
