Buick 2005 manual Inflation Tire Pressure, When to Check

Vehicle Placard: A label permanently attached to a vehicle showing the vehicle’s capacity weight and the original equipment tire size and recommended inflation pressure. See “Tire and Loading Information Label” under Loading Your Vehicle on page 4-31.

Inflation - Tire Pressure

Tires need the correct amount of air pressure to operate effectively.

Notice: Do not let anyone tell you that under-inflation or over-inflation is all right. It is not. If your tires do not have enough air (under-inflation), you can get the following:

•Too much flexing

•Too much heat

•Tire overloading

•Premature or irregular wear

•Poor handling

•Reduced fuel economy

If your tires have too much air (over-inflation), you can get the following:

•Unusual wear

•Poor handling

•Rough ride

•Needless damage from road hazards

A Tire and Loading Information label is attached to the vehicle’s center pillar (B-pillar), below the driver’s door latch. This label shows your vehicle’s original equipment tires and the correct inflation pressures for your tires when they are cold. The recommended cold tire inflation pressure, shown on the label, is the minimum amount of air pressure needed to support your vehicle’s maximum load carrying capacity.

For additional information regarding how much weight your vehicle can carry, and an example of the tire

and loading information label, see Loading Your Vehicle on page 4-31. How you load your vehicle affects vehicle handling and ride comfort, never load your vehicle with more weight than it was designed to carry.

When to Check

Check your tires once a month or more. Do not forget to check the compact spare tire, it should be at

60 psi (420 kPa). For additional information regarding the compact spare tire, see Compact Spare Tire

on page 5-94.
