Tire balancing: diagnose vibration and fix it

Tire balancing distributes weight evenly around each wheel-and-tire assembly so it spins smoothly. When balance is off, you feel it as a shake or shimmy — and it can lead to faster tire wear and stress on suspension parts.

Free tire rotation and balance are included with tires purchased and installed at Discount Tire. Not sure if you need it? Use the guide below, then schedule a visit and we’ll confirm the cause and fix the shake.

Do I need my tires balanced?

You likely need balancing if you notice any of the following, especially at highway speeds (about 45 mph and up):

• Steering wheel vibration that gets worse as speed increases
• A buzz or shake felt in the seat or floorboard
• New vibration after hitting a pothole or curb, or after tire service
• Uneven or cupped tread wear

A quick rule of thumb: - Vibration in the steering wheel often points to the front tires/wheels. - Vibration in the seat/floor can point to the rear.

If you’re unsure, we can inspect and road test. Book a tire inspection and we’ll pinpoint the cause.

What causes vibration?

Most vibrations come from tire/wheel imbalance or slight out‑of‑round conditions (runout). There are two kinds of imbalance:

• Static imbalance: a light/heavy spot causes an up‑and‑down hop.
• Dynamic imbalance: unequal weight across the wheel’s width causes a side‑to‑side wobble.

Other issues can feel similar and may need different fixes: - Bent or damaged wheel - Out‑of‑round tire - Suspension wear or misalignment - Brake-related vibration under braking

When symptoms persist after standard balancing, we use road force balancing to measure tire/wheel uniformity under load and correct more complex causes.

How balancing works

A technician mounts your wheel-and-tire assembly on a calibrated balancer that spins it at speed to locate heavy spots. We then apply small clip‑on or adhesive weights in precise locations so the assembly shares the same center of gravity and spins true. This reduces vibration and helps tires wear evenly. See what’s included with our rotation and balance service.

How often should I balance?

• Every 6,000 miles, or at each tire rotation
• Any time you install new tires or repair a tire
• After a significant impact (pothole/curb) or when vibration starts

Pairing balance with regular rotations helps prevent irregular wear and extends tire life. If you bought your tires from us, rotation and rebalancing are free for the life of the tires.

Quick checks before you book

• Check tire pressures; low or uneven pressure can mimic imbalance. Get a free air check — no appointment needed.
• Look for visible damage to tires or wheels.
• Brush off packed mud/ice that can throw a wheel out of balance.

If the shake remains, schedule balancing. Driving long with vibration can accelerate tire and suspension wear.

• Prefer to bundle balance with new tires? Rotation, rebalancing, flat repair, air checks, and inspections are included for the life of the tires when you buy from us. Start with Treadwell, your tire guide or shop tires.
