Do I Need an Alignment or a Balance?

Balancing fixes a vibration at speed. Alignment fixes a car that pulls, wanders, or wears its tires unevenly. If the wear is uneven, the alignment gets sorted first, because otherwise the alignment will chew a fresh balance straight back out.

Two different services for two different problems, routinely confused because both involve wheels and both can show up as something feeling wrong. If the symptom is specifically a shake at speed, start with why a steering wheel shakes at highway speed.

What is the difference between alignment and balancing?

Balancing deals with how weight is distributed around a wheel and tire, and it stops vibration at speed. Alignment deals with the angles the wheels sit at relative to the road and to each other, and it stops the vehicle pulling and stops the tires wearing unevenly.

Side by side

Which one do you need?

Read the symptom: it points to a different system. A vibration that appears at highway speed and eases when you slow down is balance, a weight issue in the wheel and tire. A vehicle that pulls on a straight flat road, or tires wearing more on one edge than the other, is alignment, an angle issue in the suspension.

When someone comes in with a vibration, we take a look at the tires first. We check the inside edge. If the tire is really bad we recommend replacement, because balancing a finished tire is throwing money at it. If the tire is still good we can balance it, and if we see uneven wear we recommend an alignment before they get too far into it. We do not do alignments here. We can diagnose them, and then they go to their mechanic for that part. We would rather tell somebody exactly what we are seeing than sell them a balance that was never going to fix their problem.

If the vibration turns out to be a damaged tire rather than a balance issue, that's a repair, not a rebalance, and we'll tell you which applies.

Signs it is alignment

• The vehicle pulls to one side on a straight, flat road
• The steering wheel sits off centre while you are driving straight
• One edge of the tread is noticeably more worn than the other
• The wear is worse on the inside edge, which you have to feel by hand
• The tires are wearing in a patchy or scalloped pattern

Signs it is balance

• Vibration that starts at speed and eases when you slow
• The shake is felt through the steering wheel, front wheels, or the seat, rear wheels
• Tire wear looks even across the tread
• It appeared after new tires were fitted, or after a wheel came off

Why does the order matter?

Because an unfixed alignment problem will wear a freshly balanced tire back out of true. Balancing a wheel on a vehicle that is eating its tires means paying for the same job twice, once now and once after the alignment finally gets done.

The right sequence

1. Diagnose the wear. Which edges, which pattern, how far gone
2. Alignment first if the wear says alignment and the tires are still usable
3. Replace the tires instead if the existing set is too far gone to save
4. Balance after, so the balance holds

The exception is a straightforward vibration with even wear and no pulling. That is a balance, full stop, and there is nothing to sequence.

Timing an alignment check around the seasonal swap is efficient too: the Fredericton winter tire changeover schedule has the current dates.

What does the wear pattern tell you?

Where a tire wears says which problem you have, and reading it correctly avoids guessing. Centre wear is over-inflation, both edges is under-inflation, one edge alone is an alignment angle, and a patchy, uneven pattern is also alignment. Catching the pattern early keeps the damage from spreading across the rest of the tread.

The inside edge is the one that catches people, because it is invisible from where you park. Run your hand along the inner face of the tread and feel whether it is worn down compared to the outside.

What does it cost?

Balancing a full set starts at $45 for a small vehicle, and it is included at no charge with any off-rim tire change. The price scales with vehicle size because larger wheels carry more weight to correct. Alignment is not something we price, because it is not something we do, so that cost sits with whichever mechanic handles the referral.

If the same visit is also due for a seasonal swap, see Fredericton tire change rates while you're checking the balance price.

Pre-tax. Includes machine balance, tire shine, and install.

Key takeaways

• Balance fixes vibration at speed. Alignment fixes pulling and uneven wear.
• We balance. We do not align. We will diagnose the alignment and send you on with a clear description.
• If wear is uneven, alignment goes first or you pay for the balance twice.
• Centre wear is over-inflation, both edges is under-inflation, one edge is alignment.
• Feel the inside edge by hand. That wear is invisible from the driveway.
• If the tires are too far gone, neither service is the answer. New tires are.

Frequently asked questions

What is the difference between alignment and balancing? Balancing is about weight distribution around a wheel, and it fixes vibration at speed. Alignment is about the angles the wheels sit at relative to the road and each other, and it fixes pulling, wandering, and uneven wear. Different problems, different fixes.

Do you do wheel alignments? No. We do tire and wheel work, and alignment is not part of that. What we do is read the wear on your tires, tell you what it points at, and send you to a mechanic with a clear description rather than a guess.

Should I get an alignment before or after new tires? Before, or at the same time. Fitting new tires to a vehicle with a known alignment problem means the alignment starts wearing the new set immediately. If the wear pattern says alignment, deal with that first.

How do I know if I need an alignment? The vehicle pulls to one side on a straight flat road, the steering wheel sits off centre when you are going straight, or the tires are wearing unevenly across the tread. That last one is the reliable sign, and it shows up before you feel anything.
