What Causes This on UK Cars

The exact cause depends on your make, model, year and mileage. These are the most common faults that produce this symptom — listed in order of probability on most UK vehicles.

Tyre Pressure Difference
The simplest and most common cause of pulling is uneven tyre pressures. A tyre that is significantly under-inflated on one side creates more rolling resistance — pulling the car toward that side. Always check tyre pressures before diagnosing anything more complex. This takes two minutes and costs nothing.
💰 Typical cost: Free
⚠ Check immediately
Wheel Alignment Out
Incorrect wheel alignment — also called tracking — means the wheels are not pointing in the correct direction relative to each other and the road. This causes the car to pull consistently to one side. Alignment goes out from kerb strikes, pothole damage or worn suspension components. A four-wheel alignment check and adjustment takes about an hour.
💰 Typical cost: £50-£80
⚠ Medium — also causes rapid tyre wear
Seized Brake Caliper
A brake caliper that is partially seized applies constant braking force to one wheel — pulling the car strongly toward that side especially under braking. The affected wheel and brake area will feel significantly hotter than the opposite side after driving. This is a safety issue that needs prompt attention.
💰 Typical cost: £80-£250 per caliper
⚠ High — safety critical
Worn Track Rod End
Track rod ends connect the steering rack to the wheel hub. When a track rod end wears the wheel position becomes inconsistent — causing pulling, vague steering and rapid uneven tyre wear. A worn track rod end is an MOT failure and wheel alignment cannot be set correctly until it is replaced.
💰 Typical cost: £60-£150 per side including alignment
⚠ High — MOT failure
Tyre Defect
A tyre with internal structural damage — from a pothole strike or manufacturing defect — can cause persistent pulling even with correct pressures and alignment. If the car pulls only after a recent tyre change or pothole impact inspect the tyres carefully for bulges or uneven wear patterns.
💰 Typical cost: £80-£200 for tyre replacement
⚠ High — tyre failure risk

Common Questions

It depends on severity and cause. Mild pulling from alignment or tyre pressure is driveable short term. Strong pulling from a seized caliper or structural tyre fault is a safety issue — do not drive until it is diagnosed.
Pulling specifically under braking strongly suggests a seized or sticking brake caliper, or uneven brake pad wear. The side it pulls toward is usually where the fault lies.
Yes — pulling from a seized caliper, worn track rod end or significant alignment fault will cause an MOT failure. Get it checked before your test.
From free (tyre pressure) to £250 for a brake caliper replacement. A correct diagnosis avoids paying for tracking adjustments when the real cause is a worn component.
