Pontiac 2006 manual Tire Inspection and Rotation

The low-tire pressure warning light may not come on even if the tire inflation pressure is low, or it may come on when the tire inflation pressure is set correctly under the following circumstances:

•A compact spare tire, snow tires, or tire chains are installed on your vehicle.

•The tires are over-inflated, or the tire inflation pressure suddenly drops due to a tire bursting or other causes.

•The vehicle is driven on a slippery road surface such as rough or frozen roads.

•The vehicle speed is less than 19 mph (30 km/h), and the driving duration is less than five minutes.

•The tires are made by a different manufacturer or differ in tread pattern than the original equipment tires.

•Rapid acceleration/deceleration or multiple consecutive sharp turns.

•Towing a trailer.

•The vehicle is loaded over the limit or not balanced properly.

•The initialization (reset) procedure was not performed correctly after replacing or rotating tires or wheels.

•The outside temperature is below 32°F (0°C) or above 104°F (40°C).

Tire Inspection and Rotation

Tires should be rotated every 5,000 to 8,000 miles (8 000 to 13 000 km).

Any time you notice unusual wear, rotate your tires as soon as possible and check wheel alignment. Also check for damaged tires or wheels. See When It Is Time for New Tires on page 5-64and Wheel Replacement on page 5-67for more information.

The purpose of regular rotation is to achieve more uniform wear for all tires on the vehicle. The first rotation is the most important. See Part A: Scheduled Maintenance Services on page 6-4for scheduled rotation intervals.
