Tire Rotation
Since each tire performs different tasks (such as steering or front- versus rear-wheel drive), tires wear at different rates. Rotating your tires at recommended intervals extends their useful life and achieves more uniform tire wear.

It’s important to rotate your tires according to the correct tire rotation pattern. Front tires encounter different tasks than the rear tires. And a front-wheel-drive vehicle’s tires perform different tasks than those on a rear-wheel-drive vehicle. Your Owner's Manual specifies which rotation pattern is right for your vehicle.

Your Buick’s front and rear tires may also use different pressures — make sure to adjust individual tire pressure to the recommendation for each wheel position. See your vehicle's Owner's Manual for recommendations.

Tire Alignment
Alignment is critical for ensuring that you get maximum wear and performance from your tires. Poor alignment results from your vehicle's suspension and steering system becoming out of adjustment with each other. The biggest indicators of your vehicle being out of alignment are pulling one way or the other as you drive or unusual tire wear. Improper tire inflation can also cause unusual tire wear.

Your Buick vehicle may have both front- and rear-wheel alignment specifications. Your Buick dealer can recommend the alignment type that's right for your vehicle.
