Most drivers have experienced it.
You're driving along, everything seems fine, and then suddenly—
BANG.
The car jolts, the steering wheel shakes, and you've just hit a pothole.
Maybe you mutter a few choice words and carry on driving. After all, it was only a hole in the road, right?
Not necessarily.
While potholes might seem like a minor annoyance, they can cause serious damage to your vehicle and, in some cases, create dangerous driving conditions. In fact, every year, potholes cost motorists millions in repair bills and are responsible for countless breakdowns across the country.
Why Are Potholes So Bad?
Potholes don't appear overnight.
They start as tiny cracks in the road surface. Water gets into those cracks, temperatures rise and fall, and traffic repeatedly drives over the weakened area.
Eventually, the road surface breaks apart.
What starts as a small defect can quickly become a hole deep enough to damage tyres, wheels, and suspension components.
The worst part?
Many potholes fill with water, making it impossible to judge how deep they really are until you've driven straight through them.
What Happens When You Hit One?
When your vehicle strikes a pothole, the impact doesn't just affect the tyre.
The force travels through the entire corner of the vehicle, including:
-
The tyre
-
The alloy wheel
-
The suspension
-
The steering components
-
The wheel bearing
At low speeds you may get away with it.
At higher speeds, the impact can be surprisingly severe.
The Damage You Might Not Notice
Sometimes the damage is obvious.
A puncture. A cracked wheel. A warning light.
But often the real problems appear later.
You may notice:
-
A vibration through the steering wheel
-
The car pulling to one side
-
Uneven tyre wear
-
Strange noises when driving
-
Reduced handling or stability
Many drivers don't connect these symptoms to a pothole they hit days or even weeks earlier.
Your Wheels Take the Biggest Hit
Modern alloy wheels look fantastic, but they aren't indestructible.
A hard impact can bend or crack a wheel, especially if the pothole is deep or the tyre profile is low.
Even a slight bend can cause vibrations and affect how the vehicle handles.
In severe cases, the wheel may no longer seal correctly against the tyre, leading to slow air leaks.
Tyres Can Suffer Too
The tyre is your vehicle's first line of defence against potholes.
Unfortunately, it's also one of the most vulnerable components.
A pothole impact can damage the tyre's internal structure, even if the outside looks fine.
Keep an eye out for:
-
Bulges in the sidewall
-
Cuts or splits
-
Sudden pressure loss
-
Uneven wear patterns
If you spot any of these signs, the tyre should be inspected as soon as possible.
Don't Forget the Suspension
Your suspension is designed to absorb bumps and imperfections in the road.
What it isn't designed for is dropping into a crater at speed.
Repeated pothole impacts can accelerate wear on:
-
Shock absorbers
-
Springs
-
Suspension arms
-
Bushes
-
Steering components
Left unchecked, these issues can become expensive repairs.
What Should You Do After Hitting a Pothole?
If you've hit a pothole particularly hard, it's worth taking a few minutes to check your vehicle.
Ask yourself:
-
Has the steering changed?
-
Is the car pulling to one side?
-
Are there any new vibrations?
-
Does a tyre look damaged?
-
Have any warning lights appeared?
If something doesn't feel right, it's always worth having the vehicle inspected.
A simple alignment check today could prevent a much bigger repair bill tomorrow.
The Bottom Line
Potholes are more than just an inconvenience.
They can damage tyres, crack alloy wheels, knock out wheel alignment, and place extra strain on suspension components.
The next time you hear that dreaded BANG, don't just ignore it.
A quick inspection could save you money, improve your safety, and prevent a small problem from turning into a major repair.
Because when it comes to potholes, the damage isn't always visible straight away.
