For UK drivers getting ready for a summer road trip, especially families leaving London for the coast, countryside, airports or school holiday breaks, tyre problems are the last thing you want once the car is packed and everyone is strapped in. A flat tyre, low pressure warning or motorway vibration can turn a simple journey into a stressful delay. Auto King in Bethnal Green helps London drivers spot tyre issues before they become roadside problems, and this quick checklist shows you what to check before you set off.
When the boot is full, the kids are in the back, and the sat nav says three hours to go, your tyres are doing a lot more work than usual. Long motorway driving, extra luggage, warmer weather and higher speeds all put more strain on them.
The good news is that a proper tyre check before a long journey in the UK only takes around five minutes. Work through the checklist below before your next summer drive and you will reduce the risk of poor handling, blowouts, fuel waste and unnecessary breakdown stress.
Quick Road Trip Tyre Checklist
Before you leave, tick off these six checks:
- Check tread depth across each tyre
- Check tyre pressure when the tyres are cold
- Inspect for cuts, cracks, bulges and sharp objects
- Check the spare wheel or tyre repair kit
- Get pulling, vibration or uneven wear checked early
- Plan for heat, luggage and long motorway speeds
1. Check Tread Depth Before You Leave
Tread depth is one of the most important parts of any car tyre check before a holiday. It affects how well your tyres grip the road, especially if you hit sudden summer rain on the M1, M25, A12 or A13.
In the UK, the legal minimum tyre tread depth for cars is 1.6mm across the central three quarters of the tyre and around the full circumference. That is the legal limit, not the ideal point to start thinking about replacement.
For summer road trips, it is sensible to check your tyres well before they reach the limit. A long motorway journey on worn tyres can mean longer stopping distances, weaker wet grip and a higher chance of failing a roadside inspection or MOT.
Before setting off, it is worth learning how to check your tyre tread depth properly so you can spot worn or unsafe tyres before a long motorway journey.
How to Do the 20p Tyre Tread Test
A quick way to check tread depth is the 20p test:
- Place a 20p coin into the main tread grooves.
- Check whether the outer band of the coin is hidden.
- If the outer band is visible, your tread may be below the legal limit.
- Repeat the check in several places across each tyre.
Do not only check one groove. Tyres can wear unevenly, especially if the wheel alignment, suspension or pressure is wrong.
2. Check Tyre Pressure When the Tyres Are Cold
Tyre pressure is one of the most commonly missed checks before a long drive. It also has a big effect on motorway driving tyre safety.
Here’s the thing, tyre pressure should be checked when the tyres are cold. Ideally, do it before driving, or after the car has been parked for at least a few hours. Once you have driven even a short distance, heat builds up inside the tyre and expands the air. That can give you a falsely high reading.
If you check pressure after driving to a petrol station, the numbers may look fine even when the tyre was underinflated before the journey.
Where to Find the Correct Tyre Pressure
Do not use the maximum pressure printed on the tyre sidewall. That is not the normal recommended pressure for your car.
Your correct tyre pressure is usually found in one of these places:
- A sticker inside the driver’s door frame
- The fuel filler flap
- The owner’s handbook
- The manufacturer’s online guide
Most cars have different figures depending on load. A fully loaded car with passengers, luggage, pushchairs, bikes, cool boxes or camping gear may need a higher pressure than your normal daily driving figure.
Before a summer road trip, check the handbook for the loaded vehicle pressure. This matters because extra weight makes tyres work harder, creates more heat and can make the car feel less stable at motorway speeds.
Why Low Tyre Pressure Is a Problem on Long Drives
Underinflated tyres can cause:
- Higher fuel use
- Poorer steering response
- Extra heat build-up
- Faster tyre wear on the outer edges
- Increased risk of tyre failure
Overinflated tyres can also cause problems, including reduced comfort, reduced contact with the road and uneven centre wear.
A pressure check takes minutes, but it can make the whole journey safer and smoother.
3. Inspect Each Tyre for Visible Damage
A proper road trip tyre checklist should always include a visual inspection. Tyres can look fine from a distance, but small issues can become serious during a long motorway run.
Walk around the car and look closely at each tyre, including the inner and outer sidewalls where possible.
Look for Sidewall Cuts, Cracks or Bulges
The sidewall is the smooth outer area of the tyre. If you see a bulge, bubble or deep cut, do not ignore it. A bulge can mean the internal structure of the tyre has been weakened, often from pothole impact or kerb damage.
This is common in London driving. Hitting potholes, brushing kerbs on narrow East London roads, or mounting a kerb too sharply can damage a tyre long before a road trip begins.
Warning signs include:
- A lump or bubble on the sidewall
- Deep cracks around the rubber
- Visible cord or fabric
- A slice or tear in the tyre wall
- Repeated pressure loss in the same tyre
If you spot any of these, get the tyre checked before driving long distance.
Check for Stones, Nails or Sharp Objects
Look inside the tread grooves for:
- Nails
- Screws
- Glass
- Sharp stones
- Metal fragments
A small screw may not cause an instant flat tyre. Sometimes it creates a slow puncture that only becomes obvious after motorway driving, when heat and pressure increase.
If you see something embedded in the tyre, do not pull it out at home unless you are prepared for the tyre to deflate. It is safer to have it inspected by a garage.
Look for Uneven Wear Patterns
Uneven tyre wear often points to a bigger issue. For example:
- Wear on both outer edges can suggest underinflation
- Wear in the centre can suggest overinflation
- Wear on one side can suggest alignment problems
- Patchy or cupped wear can suggest suspension or balancing issues
This is where a quick visual check can save money. Catching the cause early may protect the rest of the tyre set.
4. Do Not Forget the Spare Wheel or Repair Kit
Many drivers check the four tyres on the car and forget the backup plan. That is a problem if something goes wrong on the motorway.
Some modern cars do not come with a spare wheel at all. Instead, they include a tyre sealant bottle and inflation kit. Others have a space-saver spare wheel, which is only designed for temporary use and usually has speed and distance limits.
Before you leave, check what your car actually has.
If Your Car Has a Spare Wheel
Check that:
- The spare tyre is present
- It is properly inflated
- The tread looks usable
- The jack is in the car
- The wheel brace is present
- The locking wheel nut key is available
The locking wheel nut key is easy to misplace. Many drivers only realise it is missing when a breakdown recovery driver asks for it on the hard shoulder.
If Your Car Has a Repair Kit
Check that:
- The sealant bottle has not expired
- The compressor is present
- The kit looks complete
- You know where the 12V socket is
- You understand the basic instructions
Tyre sealant kits do not fix every puncture. They are usually designed for small tread punctures, not sidewall damage, blowouts or large cuts.
It is much better to understand this before you need it in a lay-by with traffic rushing past.
5. If the Car Pulls or Vibrates, Get It Checked First
A car that pulls to one side or vibrates through the steering wheel should not be ignored before a long journey.
It might feel minor during short local trips around Bethnal Green, Mile End, Hackney or Bow, but motorway speeds can make the issue more obvious and more dangerous.
Common Signs Something Needs Checking
Book a tyre, alignment or suspension check if you notice:
- The steering wheel shakes at speed
- The car pulls left or right
- The steering wheel sits off-centre
- Tyres are wearing more on one edge
- The car feels unstable when braking
- There is a humming or rumbling noise from a wheel area
A pulling sensation may be caused by wheel alignment, tyre pressure differences, suspension wear or brake issues. Vibration may point to wheel balancing, tyre damage or a worn component.
Either way, it is better to deal with it before the trip, not after 100 miles of motorway driving..
6. Plan for Heat, Luggage and Motorway Speeds
Summer road trips put tyres under different stress from normal city driving. Warm weather, long stretches at 60 to 70mph, heavy luggage and repeated braking in traffic can all raise tyre temperature.
Heat is not automatically dangerous, but poor tyre condition makes it riskier. Underinflated tyres, old tyres, overloaded vehicles and damaged sidewalls are more likely to struggle when the temperature rises.
Before you leave, think about how the car is being used:
- Is the boot heavily packed?
- Are all seats occupied?
- Are you carrying roof boxes or bikes?
- Will you be driving for several hours?
- Is the route mostly motorway?
- Are the tyres already close to the legal limit?
If yes, the tyre check matters even more.
You do not need to overcomplicate it. Check pressure cold, confirm loaded pressure figures, inspect the tyre condition and do not drive on anything that looks questionable.
Extra Checks Before a Long Summer Drive
A proper pre-journey tyre check should also include a few small details that often get missed.
Check Tyre Age
Tyres age even if the tread looks acceptable. Cracking, hard rubber and low mileage ageing are more common on cars that do short trips, sit parked for long periods or do not cover many motorway miles.
The tyre date code is printed on the sidewall. It usually appears as a four-digit number. For example, 2422 means the tyre was made in week 24 of 2022.
If your tyres are old, cracked or have been unused for long periods, get them checked before a long journey.
Check Valve Caps
Valve caps help keep dirt and moisture out of the valve. Missing caps are cheap to replace, but they are still worth checking before a long trip.
Do Not Overload the Vehicle
Every car has a maximum load rating. Overloading affects braking, steering, fuel economy and tyre heat. If you are travelling with family luggage, holiday bags and roof storage, check the owner’s handbook for vehicle load guidance.
A packed car might feel normal at low speed, but it can behave very differently when braking hard on a motorway.
What Should You Do If a Tyre Warning Light Comes On Before the Trip?
If the tyre pressure monitoring system warning light comes on before you leave, do not simply reset it and carry on.
First, check the pressure in all four tyres when cold. If one tyre is noticeably lower than the others, there may be a slow puncture. Inflate it to the correct pressure, then monitor it. If the pressure drops again, get it inspected.
If the warning light stays on after pressures are corrected, the system may need checking, or there may be a sensor issue.
For a long journey, it is better to be cautious. A warning light that appears before you leave London can become a bigger headache once you are on the motorway.
When Should You Replace Tyres Before a Road Trip?
You should consider replacing a tyre before a long road trip if:
- Tread is close to the legal limit
- The sidewall has cracks, cuts or bulges
- The tyre loses pressure repeatedly
- There is uneven wear exposing one edge
- The tyre is old and showing signs of ageing
- You can see cord or structural damage
- A garage advises it is unsafe
The legal minimum is not a comfort zone. If you are carrying family, luggage and driving at motorway speeds, replacing questionable tyres before the journey is the safer option.
Final Five Minute Tyre Checklist Before You Set Off
Use this quick version before leaving:
- Tread depth checked with a 20p coin
- Tyre pressure checked cold
- Loaded vehicle pressure confirmed
- Sidewalls checked for cuts, cracks and bulges
- Tread checked for nails, screws and sharp objects
- Uneven wear checked
- Spare wheel or repair kit checked
- Jack, wheel brace and locking wheel nut key located
- Tyre warning lights investigated
- Pulling, vibration or steering issues checked by a garage
If anything looks wrong, do not leave it until after the trip. Tyres are too important for guesswork.
