Why Your Car Should Drive Straight
On a flat road, your vehicle should continue straight with minimal steering input.
If it constantly drifts left or right, something is forcing the wheels out of alignment.
This means:
- tyres are wearing unevenly
- steering geometry is incorrect
- braking stability is reduced
Left unfixed, it can destroy tyres within weeks.
Quick Diagnosis Guide
| When It Pulls | Likely Cause |
|---|---|
| Always while driving | Wheel alignment |
| Only while braking | Brake caliper problem |
| After new tyres | Pressure or fitting issue |
| After pothole hit | Bent wheel or suspension |
| Steering wheel off-centre | Tracking misalignment |
1. Wheel Alignment (Most Common Cause)
The number one reason cars pull sideways is incorrect alignment.
Even a small angle difference forces the vehicle to steer itself.
1.1 Common after:
- potholes
- kerb impact
- worn suspension
- speed bumps
1.2 Signs
- Steering wheel not straight
- Car drifts when you release wheel
- Uneven tyre wear
Fix with professional wheel alignment service
2. Uneven Tyre Pressure
A very common but overlooked cause.
If one tyre has lower pressure, it creates rolling resistance pulling the car.
2.1 Signs
- Sudden pulling
- No vibration
- Happens after temperature drop
Check pressure when tyres are cold.
Visit for tyre inspection
3. Different or Worn Tyres
Different tyre grip levels create imbalance.
3.1 Signs
- Pulling after tyre replacement
- Worse in rain
- Heavy steering
Replace with matching cheap tyres or part worn tyres
4. Brake Caliper Sticking
A sticking brake constantly slows one wheel.
Car pulls toward that side.
4.1 Signs
- Pulls more when braking
- Burning smell
- One wheel hotter
Fix with brake repair service
5. Suspension Damage
Bent suspension changes wheel angle permanently.
Usually after pothole or minor accident.
5.1 Signs
- Steering wheel crooked suddenly
- Car unstable
- Alignment doesn’t stay fixed
Inspect with suspension repair
Is It Dangerous?
Yes especially in emergency braking.
The car may:
- swerve during braking
- lose control in rain
- increase stopping distance
It’s also a common MOT failure reason.
How Fast Tyres Wear If Ignored
| Distance Driven | Damage |
|---|---|
| 500 miles | uneven wear begins |
| 1500 miles | noticeable edge wear |
| 3000 miles | tyre destroyed |
Professional Diagnosis Process
A garage checks:
- Tyre pressure
- Alignment angles
- Brake drag
- Suspension play
- Wheel damage
Typical UK Repair Costs
| Repair | Typical Cost |
|---|---|
| Wheel alignment | £40–£80 |
| Tyre replacement | £60–£150 |
| Brake repair | £90–£250 |
| Suspension repair | £120–£300 |
When To Book Immediately
Book inspection urgently if:
- Pulling started suddenly
- Steering wheel crooked
- After hitting pothole
- After new tyres fitted
- Car pulls while braking
Final Advice
A car pulling to one side is an early warning sign of steering geometry failure.
Most cases are simple alignment fixes delaying leads to tyre damage and unsafe braking.
