C. Tire Change Safety Precautions
When you must make the repair on a wheel (demount and mount the rim and
tire), follow these precautions:
DO:
(1) Follow the procedures (assemble and disassemble) that you find in the
tire change safety guidelines or other instruction manual.
(2) Before you start to disassemble the wheel, fully deflate the tire.
(3) Replace the parts with damage, cracks, signs of wear and corrosion.
(4) Before you inflate the tire, make sure that you examine the removable
ring. It must be seated correctly.
(5) Examine the side ring and make sure that it is not too loose. This is an
indication of parts that do not match correctly.
(6) Do not inflate the tire until the safety cage is in position.
(7) After you inflate the tire, make sure that the rim ring clearance is between
0.06 in. to 0.25 in. (1.6 mm to 6.3 mm).
(8) After you complete the repair, examine the wheel nuts and rim clamps for
wear, corrosion, proper centering and the correct torque.
DO NOT:
(1) Mix the parts. This is a dangerous condition. Make sure that the side ring
and lock ring agree with the identification marks on the base.
(2) Lift a load or move a load that is above the capacity of the crane.
(3) Inflate a tire if it is fully flat or near flat. You must first disassemble and
examine the tire and rim assembly.
(4) Use a tire and rim configuration that is not approved by the Tire & Rim
Association (TRA).
