A car that constantly wants to drift left or right can make even a straightforward journey frustrating.
You might find yourself continually correcting the steering wheel to keep the car travelling straight. Perhaps the problem only happens when you brake, or you've noticed the steering wheel no longer sits straight when you're driving along a level road.
There isn't one single explanation for a car pulling to one side.
Sometimes something relatively simple, such as incorrect tyre pressure, could be responsible. In other cases, the problem may involve your wheel alignment, brakes, suspension or steering.
The circumstances in which the car starts pulling can provide useful clues.
Here's what could be happening.
Wheel alignment is one of the first things many motorists associate with a car pulling to one side.
Your wheels need to sit at specific angles relative to the vehicle and the road. These angles can move outside the manufacturer's intended settings over time or after an impact.
Potholes, kerbs and other road hazards can all potentially affect alignment.
Possible signs of poor wheel alignment include:
However, pulling doesn't automatically mean your alignment is wrong.
Tyres, brakes and suspension problems can produce similar symptoms, so it's worth considering the complete picture rather than assuming an alignment adjustment will automatically solve the problem.
Before assuming there's a more complicated fault, check the tyres.
A significant difference in pressure between tyres can affect the way a vehicle behaves on the road.
If one tyre is substantially underinflated, its rolling characteristics will differ from the tyre on the opposite side, which may contribute to the car drifting or pulling.
Check the pressures when appropriate against the figures recommended for your particular vehicle.
You'll normally find the manufacturer's tyre pressure information in the owner's manual or on a label fitted somewhere on the vehicle, often around the driver's door opening or fuel filler area.
Don't simply inflate every tyre to the number printed on the tyre sidewall. That isn't normally the manufacturer's recommended operating pressure for your car.
Tyre pressure isn't the only tyre-related possibility.
Inspect the condition of the tyres as well.
Uneven wear can sometimes indicate an underlying alignment, suspension or tyre problem and may affect the way the vehicle handles.
Look for:
Tyres are particularly worth checking as wetter weather approaches. Our End of Summer Car Maintenance: What Should You Check? guide covers tyres, brakes, battery, lights, fluids and other useful seasonal checks.
Tyre wear is particularly useful because it can sometimes provide evidence that another problem has been present for some time.
Correcting the underlying cause is important rather than simply fitting replacement tyres and allowing the same wear pattern to develop again.
If the vehicle pulls particularly strongly when you press the brake pedal, the braking system deserves attention.
Braking force should be applied in a controlled and balanced way.
A problem affecting one side of the vehicle could potentially cause the car to pull under braking.
Possible causes can include issues involving:
For example, a sticking or poorly operating caliper may affect how the brake on one wheel behaves.
Don't try to diagnose the exact component purely from the direction in which the vehicle pulls. A proper inspection is much more reliable.
If worn brake pads turn out to be part of the problem, our Brake Pad Replacement Cost UK (2026) guide explains typical replacement costs and when brake discs may also need attention.
This is worth treating separately from a car that constantly drifts while cruising.
If the vehicle drives reasonably straight but moves noticeably left or right as soon as you apply the brakes, there could be an imbalance within the braking system.
Pay attention to other symptoms such as:
If you're also hearing brake noise, read our Why Are My Brakes Squeaking? guide for the common causes of squeaking and when your brakes should be inspected.
A car that becomes difficult to control under braking should be inspected promptly.
Your suspension does much more than make the car comfortable.
It helps maintain the position of the wheels and tyres relative to the road, so worn or damaged suspension components can affect steering and handling.
Potential problems can involve components such as:
Exactly which components your vehicle uses will depend on its suspension design.
You might also notice knocking or clunking noises, uneven tyre wear, unusual movement over bumps or changes in how the vehicle handles.
Because suspension and wheel alignment are closely related, damaged or worn suspension components may need addressing before an accurate alignment can be completed.
The steering system contains several components responsible for translating movement of the steering wheel into movement at the road wheels.
Wear, damage or excessive play within steering components can affect how accurately the vehicle responds.
Possible accompanying symptoms include:
Steering problems shouldn't be ignored, particularly if the behaviour of the car has changed noticeably.
Two tyres of the same nominal size won't necessarily behave identically if their condition, construction or wear differs significantly.
A damaged tyre or certain irregular wear patterns can potentially cause a vehicle to pull.
If a pulling problem begins immediately after tyres have been replaced, rotated or repaired, mention this when having the vehicle inspected.
It can help narrow down the possible cause.
Not every slight drift indicates a mechanical problem.
Roads aren't always perfectly flat.
Many have a slight slope or camber designed partly to help water drain away from the road surface.
That can sometimes make a vehicle naturally drift slightly towards one side.
The difference is usually consistency.
If your car strongly pulls in the same direction across different roads, requires constant correction or has recently started behaving differently, road camber alone becomes a less convincing explanation.
Another common symptom is a steering wheel that appears slightly turned even though the car is travelling straight.
Wheel alignment can be one possible cause.
However, if the steering wheel position has changed suddenly, particularly after hitting a pothole or kerb, it's sensible to have the vehicle inspected.
Don't simply concentrate on making the steering wheel look straight.
The underlying wheel, steering and suspension geometry needs to be correct.
Potentially, yes.
A substantial pothole impact can affect tyres, wheels, suspension components and wheel alignment.
After hitting a particularly severe pothole, look out for:
If something suddenly feels different immediately after an impact, it's worth getting it checked.
Yes, particularly if the impact is substantial.
Striking a kerb can potentially alter alignment or damage a tyre, wheel or suspension component.
Even if there isn't obvious external damage, a change in steering behaviour afterwards can indicate that something has moved or been damaged.
There isn't a universal answer.
A car pulling left could be influenced by tyre pressures, tyre condition, alignment, brakes, suspension, steering or even the road itself.
The direction of the pull alone generally isn't enough to diagnose the problem.
Instead, think about when it happens.
Does it pull continuously?
Only when braking?
Only on certain roads?
Did it begin after hitting a pothole?
Those details can be much more useful when the vehicle is inspected.
The same principle applies if the vehicle pulls to the right.
Don't assume there is one specific fault associated with a right-hand pull.
Tyres, alignment, brakes, suspension and steering all remain possible areas to investigate.
If the problem is persistent, getting the vehicle inspected is the most reliable way to identify the cause.
If the problem started immediately after tyre replacement, it's worth going back to the garage or tyre fitter.
There could be several possibilities, including tyre pressures, the tyres themselves or an existing alignment issue becoming more noticeable.
The timing is useful information.
Explain that the vehicle wasn't pulling before the tyres were fitted and describe exactly when the problem occurs.
It might, if incorrect wheel alignment is actually causing the problem.
But wheel alignment isn't a universal cure for a vehicle that pulls.
If the underlying problem is a damaged tyre, sticking brake, worn suspension component or steering fault, adjusting the alignment won't necessarily solve it.
That's why diagnosis matters.
If the car is pulling and you're not sure why, having the relevant components checked before assuming it simply needs alignment can save time and unnecessary work.
The appropriate alignment service depends on the vehicle and what adjustments its suspension allows.
A front wheel alignment concentrates on the front wheels, while a more comprehensive four-wheel alignment assesses the relationship and geometry across all four wheels.
Not every adjustment is possible on every vehicle.
If you're unsure which service your car needs, the garage carrying out the work can advise based on the vehicle and the measurements taken.
Compare Repair includes options for Front Wheel Alignment and 4 Wheel Alignment, making it easier to compare relevant services where available.
Incorrect alignment can contribute to uneven or accelerated tyre wear.
That matters because tyres aren't cheap.
If a tyre repeatedly scrubs against the road at an incorrect angle, parts of the tread can wear faster than they otherwise would.
Correcting an alignment problem early may therefore help you get better use from your tyres.
However, if a tyre has already been significantly damaged or worn unevenly, correcting the alignment won't restore the lost tread. The tyre itself may also need attention.
It depends on how severe the problem is and what's causing it.
A very slight tendency to follow the camber of a road isn't the same as a vehicle suddenly pulling hard under braking.
Treat the problem more seriously if:
If the vehicle feels difficult to control or you suspect a serious tyre, steering, suspension or brake problem, don't continue driving simply to see whether it improves.
Arrange an inspection if the vehicle consistently pulls despite the tyre pressures being correct.
You should also consider getting it checked if:
The sooner you identify the cause, the better chance you have of addressing it before it contributes to additional tyre wear or another problem.
If your MOT is approaching too, our MOT Checklist covers some of the key areas worth checking before test day.
A car pulling left or right certainly can be caused by incorrect wheel alignment.
But that's only one possibility.
Tyres, brakes, suspension and steering can all influence whether a vehicle travels straight.
The most useful clue is often when the problem occurs.
A car that constantly drifts may point you in a different direction from one that suddenly pulls when the brakes are applied.
Either way, if the behaviour has noticeably changed, it's worth finding out why.

Why is my car suddenly pulling to one side?
A sudden change could be associated with tyre pressure or damage, wheel alignment, brakes, suspension or steering. If the car has noticeably changed behaviour, particularly after an impact, have it inspected.
Why does my car pull to the left when driving?
Possible causes include tyre pressure, tyre wear, wheel alignment, brakes, suspension and steering. Road camber can also cause a slight drift, so the direction alone isn't enough to identify a fault.
Why does my car pull to the right?
The same range of issues can cause a vehicle to pull right. Check tyre pressures first, then consider an inspection if the problem persists.
Why does my car pull when I brake?
A vehicle that pulls specifically under braking may have a problem affecting the braking system, although other factors can also influence vehicle behaviour. Have it inspected, particularly if braking performance has changed.
Can low tyre pressure make a car pull?
A significant pressure difference between tyres can affect how a car behaves. Check all tyre pressures against the vehicle manufacturer's recommendations.
Does a car pulling mean the wheel alignment is bad?
Not necessarily. Incorrect wheel alignment is one possibility, but tyres, brakes, suspension and steering can produce similar symptoms.
Can a pothole knock out wheel alignment?
A significant pothole impact can potentially affect alignment and may also damage a tyre, wheel or suspension component.
How do I know if my car needs wheel alignment?
Common clues can include pulling, an off-centre steering wheel and uneven tyre wear. Proper alignment equipment is required to measure the wheel angles accurately.
Why is my steering wheel crooked when driving straight?
Incorrect wheel alignment is one possible explanation, although steering or suspension issues can also contribute. If the steering-wheel position has changed, consider having the vehicle checked.
Should I get four-wheel alignment or front wheel alignment?
That depends on the vehicle, its suspension design and what needs adjusting. A garage can measure the alignment and advise which service is appropriate.
If your car keeps pulling to one side and you've discovered a problem with your wheel alignment, brakes, suspension or another part of your vehicle, Compare Repair can help you find and compare relevant garage services.
