Chevrolet Trax: Replacement wheels description

Replace the wheel if any of the following conditions exist:

• The wheel exhibits excessive runout.
• The wheel is bent.
• The wheel is cracked.
• The wheel is severely rusted.
• The wheel is severely corroded.

NOTE: Air leaks caused by porosity on aluminum wheels are repairable.

WARNING: If you are replacing the wheel(s), the wheel stud(s), the wheel nut(s) or the wheel bolt(s), install only new GM original equipment parts.

Installation of used parts or non-GM original equipment parts may cause the wheel to loosen, loss of tire air pressure, poor vehicle handling and loss of vehicle control resulting in personal injury.

• The wheel leaks air.

CAUTION:

The use of non-GM original equipment wheels may cause:

• Damage to the wheel bearing, the wheel fasteners and the wheel
• Tire damage caused by the modified clearance to the adjacent vehicle components
• Adverse vehicle steering stability caused by the modified scrub radius
• Damage to the vehicle caused by the modified ground clearance
• Speedometer and odometer inaccuracy

Replace the wheel, the wheel studs and the wheel/nuts, or the wheel bolts if applicable, if any of the following conditions exist:

• The wheel has elongated bolt holes.
• The wheel/nuts, or bolts if applicable, loosen repeatedly

Steel wheel identification is stamped into the wheel near the valve stem.

Aluminum wheel identification is cast into the inboard side of the wheel.

STEEL WHEEL REPAIR DESCRIPTION

CAUTION: Do not heat wheels in an attempt to soften them for straightening or repair damage from striking curbs, etc. Do not weld wheels. The alloy used in these wheels is heat-treated and uncontrolled heating from welding affects the properties of the material.

CAUTION: The use of tubes in tubeless tires is not a recommended repair due to the fact that speed ratings are greatly reduced.

You can repair porosity in aluminum wheels. If leaks are found in a steel wheel, replace the wheel with a wheel of original equipment quality.

TIRE INFLATION DESCRIPTION

When you inflate the tires to the recommended inflation pressures, the factory-installed wheels and tires are designed in order to handle loads to the tire's rated load capacity. Incorrect tire pressures, or under-inflated tires, can cause the following conditions:

• Vehicle handling concerns
• Poor fuel economy
• Shortened tire life
• Tire overloading

Inspect the tire pressure when the following conditions apply:

• The vehicle has been sitting at least 3 hours.
• The vehicle has not been driven for more than 1.6 km (1 mi).
• The tires are cool.

Inspect the tires monthly or before any extended trip. Adjust the tire pressure to the specifications on the tire label. Install the valve caps or the extensions on the valves. The caps or the extensions keep out dust and water.

The kilopascal (kPa) is the metric term for pressure. The tire pressure may be printed in both kilopascal (kPa) and psi. One psi equals 6.9 kPa.

Inflation Pressure Conversion (Kilopascals to PSI)

Tires with a higher than recommended pressure can cause the following conditions:

• A hard ride
• Tire bruising
• Rapid tread wear at the center of the tire

Tires with a lower than recommended pressure can cause the following conditions:

• A tire squeal on turns
• Hard steering
• Rapid wear and uneven wear on the edge of the tread
• Tire rim bruises and tire rim rupture
• Tire cord breakage
• High tire temperatures
• Reduced vehicle handling
• High fuel consumption
• Soft riding

Unequal pressure on the same axle can cause the following conditions:

• Uneven braking
• Steering lead
• Reduced vehicle handling

Refer to the Tire Placard for specific tire and wheel applications and tire pressures.
