Loosen the lug nuts and raise the tire to change. If you have a jack, its head should be placed in the mainframe rail on the underside of your Airstream, toward the rear wheels. The area will be labeled "jack" with an arrow pointed to the area in which you should place the jack head. If you do not have a jack, you will need to drive your Airstream onto a ramp or a device designed to raise your tires.
Chock the remaining wheels for safety. Loosen the lug nuts with a tire iron and remove the tire. When you are removing the wheel for the spindle, mark it to ensure you replace the new tire in the same position on the drum. If you are mounting on a different drum, you will need to lightly sand any corrosion or loose materials from the surface of the drum.
Replace the old tire with a new one. Replace and tighten the lug nuts by hand. Remove the jack or ramp from the vehicle so that the new tire is on the ground. Use your tire iron to torque aluminum wheels between 110 and 120 foot pounds. Torque steel wheels to 95 foot pounds.
