Heavy truck flat tire and road tire service

Common situations

• Flat on a trailer tire or a drive tire
• Flat dual: the other tire of the pair then carries the whole load
• Steer tire cut or showing a bulge
• Valve stem torn off, cracked or leaking
• Tire off the bead after hitting a curb
• Loose or missing wheel nuts

What the technician does

The technician replaces the wheel or tire with one of the same size, checks the other tire of the dual pair and sets the pressures. Inflation is done inside a restraint device, as Québec’s workplace health and safety regulation requires for vehicles of 4,500 kg and more.

If a replacement tire is needed, the unit can leave with a tire in a common size, depending on PneusQuébec’s stock; give dispatch the exact size.

Why not finish the trip on a flat

In Québec, a flat, leaking or bulging tire, and a missing or loose wheel fastener, are major defects: under section 519.6 of the Highway Safety Code, the heavy vehicle may not be driven until it is repaired. They are on the circle-check defect list (vehicle safety standards regulation, Schedule III). Running on a flat dual also overloads the tire next to it.

After any wheel service, have the nuts re-torqued after 50 to 100 miles (80 to 160 km), as wheel and tire makers recommend.

What needs a shop

A cracked or bent rim, a damaged hub or bearing, or broken studs can go beyond what is fixed on a shoulder. The technician will tell you on site.
