You let go of the wheel on a straight road and the car drifts to one side. Or you have to keep the wheel slightly turned just to drive straight. Before spending time and money on repairs, it helps to understand when the pulling happens. Constant pull, pull only under braking, and pull after a tire swap usually have different causes and different levels of urgency.
Constant pull: tire pressure is free and comes first
The cheapest check is also the most common culprit behind a mild constant pull. If the pressure on one side is lower than the other, the car pulls toward the lower-pressure side. A difference of just 0.3 bar between the left and right tire is enough to feel through the steering wheel.
Drive to a gas station, equalize all four tires to the recommended pressure (sticker on the B-pillar or inside the fuel-cap door), and see if the pull disappears. If it does, find out why that tire is losing air. A damaged valve stem or a slow puncture from a nail are the usual suspects.
Another common cause of constant pulling is mismatched tires on the same axle. A tire with deeper tread has more rolling resistance, so the car drifts toward the side with the more worn tire. The rule is simple: the same axle must always carry tires of the same brand, same model, and similar tread depth.
Constant pull with good pressure: wheel alignment
If equalizing pressure does not fix the pull, the next step is alignment. Misaligned wheels (toe, camber, or caster out of specification) are the most common mechanical cause of constant pulling. The wheels are not parallel and the tires are not rolling in the same direction.
Alignment drifts gradually from driving on bad roads, but it can shift suddenly after hitting a large pothole or a curb. After the winter pothole season, alignment issues are one of the most common reasons drivers come into the shop. Replacing any suspension part (tie rod end, control arm, bushing) also requires an alignment check because every new part shifts angles by a millimetre or two.
Beyond pulling, bad alignment leaves a telltale sign: uneven wear on the front tires. If the inside or outside edge is visibly more worn than the rest of the tread, the alignment is almost certainly off. For more on how potholes and road damage affect suspension and steering, read our guide to clunking over bumps.
A specific case worth mentioning: the car tracks straight, but the steering wheel sits at an angle. You have to hold it a few degrees off-centre to go straight. This is a classic sign of misadjusted toe. The wheels are set so the car moves straight, but the steering rack centre does not match. The fix is a proper alignment where the technician corrects toe and re-centres the wheel.
Pull only when braking: caliper or pad issues
If the car tracks straight while cruising but pulls to one side under braking, the cause is almost always in the brakes, not the alignment. This is more urgent than a mild constant pull.
The most common culprit is a seized brake caliper. The caliper piston does not retract the pad far enough from the disc, so that side brakes harder than the other. Another cause is uneven pad wear: if the pads on one side are thinner or glazed, the friction coefficient differs and braking force is unequal.
A seized caliper can be spotted even without braking. After a drive, carefully bring your hand near the wheel rims without touching them. If one rim is noticeably hotter than the others, the caliper is probably not releasing fully. You may also smell burnt brakes. This is not something to postpone, because an overheated disc can warp, and in the worst case the brake can fail entirely. For more on worn-brake symptoms and when to act, see our brake service guide.
Pull after a tire or wheel change
Sometimes pulling appears right after fitting new tires or swapping wheels. If everything was fine before, three causes are most likely.
First is tire conicity. A new tire that was improperly formed at the factory creates uneven rolling resistance and pulls the car to one side. This is rare but it happens, especially with budget brands. The test is simple: swap the left and right tire on the front axle. If the direction of pull reverses, the tire is the problem.
Second is incorrect rotation. If tires were rotated so that tires with different tread depths ended up on the same axle, pulling is inevitable.
Third is that the new tires or wheels required an alignment correction that the tire shop did not perform. Any change in tire size or wheel offset can affect alignment angles, so a check after the swap is recommended.
What the mechanic does: suspension first, then alignment
Running an alignment on worn suspension is a waste of money. That is why every inspection starts with the suspension: the mechanic on a pit or lift checks joints, tie rod ends, ball joints, bushings, and links. If any part is worn, it gets replaced first, and only then does the car go on the alignment rack.
The alignment procedure itself takes about twenty minutes. The machine measures toe, camber, and caster on all wheels with lasers and compares them to factory specifications for that model. The mechanic adjusts the angles to spec, and at the end re-centres the steering wheel. A full suspension check and alignment is the most reliable way to fix the problem permanently rather than just masking it.
If you also feel vibrations along with pulling, it helps to distinguish two causes. An unbalanced tire produces vibrations that intensify at a specific speed (typically 80-120 km/h) but does not pull the car to one side. Bad alignment pulls the car but without speed-specific vibration. When both problems are present at the same time, which is not uncommon after hitting a pothole, you will feel both pulling and vibration. Balancing and alignment are two different procedures, and one does not replace the other.
On BiH roads, where potholes and broken pavement are an everyday reality, alignment goes out more often than in countries with better road surfaces. After pothole season, an alignment check is a reasonable precaution even when the steering does not pull noticeably. If you feel any pulling or notice uneven tire wear, book an appointment and we will check the suspension and alignment on the spot.
