Garages - Tire Precautions

What is important to know when removing wheels? Ensure that you are trained before working on a tire/rim assembly.

context Ensure that you are trained before working on a tire/rim assembly. Know, understand, and follow the proper safety procedures. If proper precautions are not followed, serious or fatal injuries can result.
context Loosen wheel nuts before lifting the vehicle off the ground.
context When operating on a freewheel or frame-contact lift, raise the vehicle only a few centimetres (one inch) from the floor.
context Block a vehicle securely when it is on a lift or jack to prevent rolling.
context Remove or replace the wheel from a squatting position. Avoid bending forward to minimize back strain. If available, use a mechanical lift.
context Do not place hands or wrists under the wheel well while the vehicle is suspended.
context Do not service split rim-type tires unless specifically trained in their repair and hazards.

requirement Look for damage, such as embedded stones, glass or other objects.
requirement Clean the rims, rim gutters, bead seating surfaces, and bead areas of the tires to ensure that all dirt and rust are removed from the lock ring and gutter.
requirement Check all parts. Discard any damaged, bent, worn or corroded components.

context Before inflating, make sure the tire and rim are the correct size.
context When inflating a tire, stand to the side or away from the trajectory of the tire, rim, or wheel components.
context Put the cap on the valve when finished to keep the valve clean.
context Inflate the tire to the pressure recommended by the vehicle's manufacturer. This information is usually available on the edge of the driver's door, door post, glove box, or in the owner's manual. The maximum pressure indicated on the tire may not be the pressure recommended for the vehicle.
context Confirm the inflation pressure with a tire gauge when the tires are "cold" (the vehicle has been stationary for at least three hours, or has not been driven more than 2 km).
context Remember to check tire pressure regularly. Tires lose pressure when the air temperature is colder (about 7 kPa or 1 psi for every 5°C drop in temperature) and over time (about 14 kPa or 2 psi per month).
context Do not overinflate tires. Overinflated tires do not make correct contact with the road, leading to a poor ride, handling issues, and increased wear on the tires and suspension.
context Do not inflate a tire that is in poor condition, as a blowout could occur.

requirement Refer to the vehicle's owner manual for any special instructions or precautions.
requirement Make sure the tire is the correct size for the rim.
requirement Mount the tire fully before inflating.
requirement Make sure all rim components are properly in place and secured before inflating.
requirement Support the tire securely with lifting equipment before attempting to attach the tire to the hub.
requirement Use the manufacturer's recommended rim size for the tire.
requirement Ensure that the trunk lid stays up before checking for a spare tire.
requirement Check tire pressure to prevent over-inflation or under-inflation with a tire pressure gauge.
requirement Guide the air hose back by hand on air pumps with an automatic or weighted hose rewind. Do not let the hose fly back because the metal chuck or gauge may whip and cause injury or damage. If the hose does not retract automatically, re-coil it and return the hose to the hanger.
engineering Follow ventilation instructions for patching compounds and liquids.
requirement Do not hammer on rims or components with a steel hammer to correct the seating of the flanges and to lock the ring. Use rubber, lead, plastic or brass-faced mallets and make sure the tire is uninflated.
administrative Do not weld on an inflated tire rim. Carry out welding repairs to rims with the tire removed from the rim and only if specially trained for such work.
requirement Do not attempt to repair tires larger than your equipment can handle.
