Tire rotation and alignment: how often, and why it saves you money

Rotate every 5,000–7,500 miles

Front tires on a front-wheel-drive car carry the engine's weight and do the steering and most of the braking, so they wear roughly twice as fast as the rears. Rotating moves that wear around so all four tires wear evenly and you replace them as a set.

The easy rule: rotate at every oil change. Most shops do it free or for under $30 while the car is already on the lift. On AWD vehicles it matters even more — significantly mismatched tread depths across axles can damage the center differential or transfer case.

Signs you need an alignment

Alignment is not on a fixed schedule; it is condition-based. Check it annually, and any time you notice these symptoms or hit something hard.

• The car pulls left or right on a flat, straight road
• The steering wheel is off-center when driving straight
• Uneven tread wear — especially feathering or a worn inner or outer edge
• You just hit a serious pothole or curb
• You just installed new tires (always align with new tires)
• You just had suspension or steering work done

Alignment vs balancing — different problems

People use these interchangeably and they are not related. Alignment is about the angles at which the tires meet the road; it causes pulling and uneven wear. Balancing is about weight distribution around the wheel; it causes vibration at speed, typically felt between 50 and 70 mph.

If your steering wheel shakes on the highway but the car tracks straight, you need balancing, not an alignment. Expect $15–30 per wheel.

Reading your tire wear

Tires document their own problems. Wear on both outer edges means chronic underinflation. Wear down the center means overinflation. Wear on one edge only means a camber problem. Feathered or saw-toothed edges across the tread mean a toe problem. Isolated scalloped dips mean worn shocks or struts.

Check pressure monthly, cold, against the sticker in the driver's door jamb — never the maximum pressure printed on the tire sidewall.

Getting it done locally

Alignment requires a proper rack, so not every general repair shop offers it. Dedicated tire shops across Franklin, Bellingham, Milford, Medway and Norfolk generally do, and many bundle a free rotation with tires purchased from them for the life of the set — worth asking about before you buy.

Frequently asked questions

How often should tires be rotated?

Every 5,000 to 7,500 miles — in practice, at every oil change. It is usually free or under $30 since the car is already on the lift.

How much does a wheel alignment cost?

Around $100–160 for a four-wheel alignment in the Franklin, MA area. Have it checked annually, after new tires, and after any hard pothole or curb strike.

Does an alignment fix a vibration at highway speed?

No. Highway vibration is almost always a wheel balance issue, not an alignment issue. Alignment causes pulling and uneven wear; balancing causes vibration.
