Do You Need New Tyres Before A Long Drive?

You do not automatically need new tyres before a long drive. If your existing tyres have sufficient tread, are correctly inflated, have no concerning damage and are suitable for your vehicle, there may be no reason to replace them simply because you are travelling further than usual. 

What matters is checking them properly before you leave. Long motorway journeys, extra passengers and a boot full of luggage can place different demands on your tyres, so problems such as low pressure, uneven wear or existing damage are worth identifying before you set off. 

Here is what we recommend checking before your next long journey.

The Quick Answer Before You Set Off

You should consider replacing a tyre before a long journey if it is below the legal tread requirement, damaged, unsuitable for continued use or otherwise unsafe. If it is approaching the end of its usable life, a professional inspection can also help you decide whether replacement before the trip would be sensible. 

For cars in the UK, the legal minimum tread depth is 1.6mm across the central three-quarters of the tyre and around its entire circumference. Tyres should also be correctly inflated for the vehicle and load and free from certain cuts and other defects. 

The most useful pre-journey check can be remembered as three things: 

  • Pressure: Is each tyre inflated correctly for the vehicle and load? 
  • Condition: Are there cuts, bulges, cracking or other signs of damage? 
  • Tread: Is there sufficient tread across each tyre? 

TyreSafe recommends checking pressure, condition and tread at least monthly and before long journeys.

Check Your Tread Depth Carefully

Tread is not simply about passing an MOT. Its grooves help tyres disperse water from the road, so tread condition is particularly important when driving longer distances in changeable or wet weather. 

For most cars, light vans and light trailers, UK law requires at least 1.6mm of tread across the central three-quarters of the tyre and around its entire circumference. 

Check several points around each tyre rather than measuring a single convenient spot. This matters because a tyre may not wear evenly. 

A tread depth gauge provides a more precise measurement. A 20p coin can also provide a quick indication: insert it into the main tread grooves at several points. If you can see the outer rim of the coin, TyreSafe advises having the tread checked because it could be below the legal requirement. 

If you are uncertain about the remaining tread, Turnpike Tyres provides free tyre checks before you commit to buying replacements.

Look Beyond The Amount Of Tread

A tyre can have plenty of tread remaining and still require attention. 

Walk around the vehicle in good light and inspect as much of each tyre as you can see. 

Look for: 

  • Cuts or splits 
  • Bulges or lumps 
  • Cracking Objects embedded in the tread 
  • Unusual or uneven wear Obvious sidewall damage 

Bulges and lumps can indicate internal tyre damage and should be assessed professionally. 

 An embedded nail or screw also deserves attention before a long trip. Do not assume that because the tyre is still holding air, everything is fine. 

A small puncture can cause gradual pressure loss, while continuing to drive on a severely underinflated tyre can cause additional internal damage. 

If you suspect a puncture, our puncture repair service can establish whether a safe repair is possible before replacement is considered.

Check Tyre Pressures Before Loading The Car

Correct tyre pressure is particularly important before a longer journey. 

Check the pressures when the tyres are cold and use the vehicle manufacturer's recommended settings. Depending on your vehicle, these are commonly found in the handbook, around the driver's door opening or inside the fuel filler flap. 

Do not simply inflate every tyre to the pressure printed on its sidewall. 

Also remember that the recommended pressure may differ when the vehicle is carrying more passengers, luggage or towing. Follow the manufacturer's guidance for the load you are carrying. 

Incorrect pressure affects more than tyre wear. Underinflation can affect handling and grip, increase fuel use and generate additional heat within the tyre. Overinflation can also affect grip, handling and wear. 

That makes pressure one of the simplest and most worthwhile checks you can complete before setting off.

Do Not Rely On Your TPMS Alone

A tyre pressure monitoring system is a useful safety feature, but the absence of a warning light should not replace a manual pre-journey tyre check. 

TyreSafe describes TPMS as a warning system rather than a reminder to maintain your tyres and recommends manually checking pressures before a long journey. 

If your TPMS warning light is illuminated, investigate the cause rather than resetting it and assuming the problem has gone away. 

Repeated pressure loss could indicate a puncture, valve issue or another problem. A warning light that persists after the pressures have been corrected may require further investigation. 

Our TPMS services can help if you are dealing with a persistent warning or suspected sensor problem.

Uneven Wear Can Tell You Something Else Is Wrong

Pay attention to where your tyres are wearing, not just how much tread remains. 

One tyre wearing differently from the others, or noticeably heavier wear across part of the tread, can indicate an underlying issue. 

If your vehicle also: 

  • Pulls to one side 
  • Feels different through the steering 
  • Has recently hit a substantial pothole or kerb 
  • Is wearing tyres unevenly 

it may be worth having the wheel geometry checked. 

At Turnpike Tyres, our Hunter Hawkeye 4-wheel alignment service measures the vehicle's wheel alignment accurately so appropriate adjustments can be made where required. 

Addressing the cause of abnormal wear can be more useful than simply fitting another tyre and allowing the same wear pattern to develop again.

Pay Attention To Vibration On The Road

Vibration through the steering wheel or vehicle is another symptom worth investigating before setting off on a long trip. 

There can be several causes, so vibration should not automatically be blamed on wheel balance. However, incorrectly balanced wheels can contribute to vibration and uneven tyre wear. 

If balancing is the issue, our wheel balancing service can help restore smoother wheel rotation. 

A long motorway journey is not the ideal time to discover that an existing vibration becomes increasingly noticeable at higher speeds. If the car already feels different from normal, have the cause investigated beforehand.

Do Older Tyres Automatically Need Replacing?

Age is something to consider, but you should not judge a passenger-car tyre by age alone without considering its condition and relevant manufacturer guidance. 

Rubber can deteriorate over time, particularly depending on factors such as use, storage and environmental exposure. Visible cracking is one reason to seek professional inspection. 

You can find the tyre's manufacturing information on its sidewall. If you are concerned about an older tyre, have it assessed rather than assuming that plenty of remaining tread automatically means it is suitable for a long journey.

Common Pre-Journey Tyre Mistakes

A few simple mistakes can undermine an otherwise sensible vehicle check.

Checking Only One Tyre

Inspect all four tyres individually. Wear, pressure and damage can differ significantly from one wheel to another. 

Checking Pressures When Hot

Pressure increases as tyres warm during driving. Check against the manufacturer's recommendations when the tyres are cold rather than releasing air from a warm tyre because its reading appears higher. 

Ignoring A Slow Pressure Loss

Repeatedly inflating the same tyre without investigating why it loses pressure can allow an underlying puncture or other problem to continue. 

Assuming An MOT Is Enough

A current MOT does not guarantee that a vehicle remains roadworthy today. GOV.UK explicitly states that motorists remain responsible for ensuring their vehicle is safe to drive even when it has a current MOT certificate. 

Waiting Until Departure Morning

Check your tyres early enough to deal with a problem. Discovering that a tyre needs professional attention just as you are supposed to leave creates unnecessary pressure and may limit your options. 


A Five-Minute Tyre Checklist Before A Long Drive

Before loading the car and setting off, work through this simple checklist: 

  1. Measure the pressure in every tyre while cold. 
  2. Adjust pressures according to the manufacturer's guidance and expected load. 
  3. Measure tread depth at several points around each tyre. 
  4. Inspect the tread and sidewalls for cuts, cracks, bulges and unusual wear. 
  5. Investigate nails, screws or repeated pressure loss. 
  6. Check any TPMS warning rather than simply clearing it. 
  7. Inspect the spare wheel or make sure your emergency repair equipment is usable. 
  8. Find your locking wheel nut key before you need it. 
  9. Arrange an inspection if you are uncertain about anything you find. 

These checks are useful whether you are travelling a few hundred miles for a holiday or simply expecting considerably more driving than usual.

Frequently Asked Questions

How Soon Before A Long Drive Should I Check My Tyres?

Do it early enough to resolve any problems you discover, then check the pressures again when the tyres are cold before departure. TyreSafe recommends tyre checks at least monthly and before long journeys.

What Is The Legal Tyre Tread Depth In The UK?

For cars, light vans and light trailers, the minimum is 1.6mm across the central three-quarters of the tread and around its entire circumference.

Should I Increase Tyre Pressure For A Full Car?

Possibly. Manufacturers may specify different pressures when carrying additional passengers or luggage. Use the settings provided for your particular vehicle and load rather than guessing.

Can I Drive If My TPMS Light Is On?

First check the tyre pressures and investigate why the warning has appeared. If the light remains illuminated after the pressures have been corrected, or flashes to indicate a possible system problem, arrange further investigation rather than relying on the system.

Do I Need Four New Tyres Before A Long Trip?

Not simply because you are making a long journey. Each tyre should be assessed for tread, pressure, condition and suitability. Replacement should be based on what the tyres actually need rather than the distance of one planned trip.

Give Your Tyres A Proper Check Before You Go

A long journey does not automatically mean buying new tyres. The important thing is knowing that the tyres already on your vehicle are roadworthy, correctly inflated and suitable for the driving ahead. 

Check pressure, tread and condition before departure, pay attention to unusual wear or vibration and leave enough time to deal with anything you discover. 

If you are preparing for a longer journey from Fareham or the surrounding area and are unsure about your tyres, Turnpike Tyres offers free tyre checks and straightforward advice. If your existing tyres are suitable, there is no reason to replace them unnecessarily. If they do need changing, you can search and order replacement tyres or contact our team for advice before your journey.
