Is It Cheaper to Buy Four Tyres Together? A UK Driver’s Guide
You need two new tyres, but the other two aren't far behind.
Should you replace the worn pair now and deal with the others later, or would it be cheaper to buy all four tyres together?
It's a common question, particularly when four new tyres can represent a significant expense.
The short answer is:
Buying four tyres together can sometimes work out better financially, but it isn't automatically cheaper, and you shouldn't replace perfectly serviceable tyres purely because you're expecting a bulk discount.
Prices vary according to tyre size, brand, tyre model, availability, fitting arrangements and any current offers.
The better question is whether replacing four tyres now makes more sense than replacing two now and potentially paying for another tyre purchase and fitting visit later.
Here's how to work it out.
Is There a Discount for Buying Four Tyres?
Not necessarily.
Tyres aren't universally sold under a "buy four and save" pricing model.
Sometimes a retailer, manufacturer or fitter may run a promotion involving multiple tyres. At other times, the price per tyre may be exactly the same whether you buy one, two or four.
That's why you should compare the actual fitted cost rather than assuming four tyres automatically qualify for a discount.
For example, imagine a tyre costs £70.
Four tyres would cost £280 before considering any applicable fitting or additional charges.
Unless there is a specific multi-buy offer or another cost difference, buying four hasn't made each tyre cheaper.
However, there are other ways replacing four at once could affect the overall cost.
Why Buying Four Tyres Together Can Sometimes Make Financial Sense
Even without a four-tyre discount, there are situations where replacing all four together may be worth considering.
1. You May Avoid Another Fitting Visit Soon
Suppose your front tyres need replacing now while your rear tyres are also approaching replacement.
Buying two today could mean returning to a fitter several months later for the other two.
Replacing all four together gives you one purchase and one fitting appointment.
Whether this actually saves money depends on the fitter's charges and the services required, so compare the total cost before deciding.
2. Promotions May Apply to Multiple Tyres
Tyre manufacturers and retailers sometimes run promotions based on the number of tyres purchased.
A four-tyre purchase could therefore occasionally qualify for an offer that isn't available when purchasing one or two tyres.
Don't assume such an offer exists. Check the current price and promotion terms when you're ready to buy.
3. You Can Compare the Full Cost at Once
Replacing all four also gives you a clearer picture of what the vehicle's next set of tyres will cost.
Instead of:
two tyres now + unknown tyre prices later + another fitting appointment
you have:
four tyres + fitting now
For drivers who already know all four tyres are approaching replacement, that certainty may be useful.
But Buying Four Tyres Isn't Cheaper If You Don't Need Four
This is the important part.
Imagine your front tyres need replacing but your rear tyres remain in good condition with substantial usable tread.
Replacing all four purely in the hope of getting a slightly better deal could mean discarding two tyres that still have useful life remaining.
Any multi-buy saving could easily be outweighed by the cost of replacing tyres earlier than necessary.
For example:
Option A
Replace two tyres now at £70 each: £140
The other two remain serviceable.
Option B
Replace four tyres at £65 each under a hypothetical multi-buy offer: £260
Yes, each tyre is £5 cheaper.
But you've spent an additional £120 today and replaced two tyres that may not yet have needed replacing.
The lowest price per tyre isn't necessarily the lowest overall cost.
When Should You Consider Replacing All Four?
There are several situations where buying four tyres deserves consideration.
All Four Are Similarly Worn
If all four tyres were fitted at roughly the same time and have worn at similar rates, they may naturally reach replacement condition together. In this situation, purchasing four at once can be straightforward.
The Remaining Pair Will Need Replacing Soon
Perhaps two tyres have reached the point where they need replacing while the other two are getting close. Ask the fitter to assess the remaining tyres. You can then compare the cost and convenience of replacing four today against buying another pair in the near future.
Your Vehicle Has Specific Requirements
Some vehicles, particularly certain four-wheel-drive or all-wheel-drive systems, can have strict manufacturer requirements or recommendations concerning differences between tyres and tread depths. Learn more in our guide on whether to replace tyres in pairs or all four, and review UK tyre mixing rules rather than making the decision purely on price.
You Want a Consistent Set of Tyres
Replacing all four can give you the same tyre model and specification across the vehicle, where appropriate. However, don't replace otherwise suitable tyres purely for visual consistency without considering whether replacement is actually necessary.
When Does Buying Two Tyres Make More Sense?
There are plenty of situations where two tyres may be the more economical purchase. For example:
- two tyres still have substantial usable tread
- only one axle has experienced significant wear
- two tyres were replaced recently
- one pair has been damaged while the other remains serviceable
- there is no meaningful financial benefit from replacing four
- your vehicle doesn't require all four to be replaced together
If two tyres can continue to be used safely and appropriately, keeping them in service allows you to use more of what you've already paid for.
What About Replacing Just One Tyre?
Sometimes only one tyre needs replacement because of sudden damage or a puncture. Before making a purchase, see our advice on tyre repair vs replacement.
Whether replacing a single tyre is appropriate depends on factors including:
- the condition of the tyre on the opposite side
- tread-depth differences
- tyre type and specification
- vehicle drivetrain
- manufacturer recommendations
Don't automatically turn a single damaged tyre into a four-tyre purchase. Have the situation assessed and check your vehicle manufacturer's guidance where relevant.
Two Tyres Now vs Four Tyres Now: A Better Way to Compare the Cost
Instead of looking only at the advertised tyre price, compare the complete scenarios. Imagine you've found a suitable tyre for £65.
Option 1: Buy Two Now
Tyres: 2 × £65 = £130
You then potentially need another two tyres later. The future price may be higher, lower or unchanged. There may also be another fitting appointment and associated costs.
Option 2: Buy Four Now
Tyres: 4 × £65 = £260
You spend more today but complete the replacement in one visit.
Option 3: Buy Four Under a Promotion
Imagine a genuine current promotion effectively reduces the total four-tyre cost. Now replacing four becomes financially more interesting, provided the other two tyres genuinely warrant replacement.
This is why there isn't one universal answer. You need to compare:
condition of existing tyres + current tyre prices + fitting costs + applicable promotions + how soon the remaining tyres will need replacement.
Should You Buy Four Budget Tyres Instead of Two Premium Tyres?
This is another decision drivers may face when working with a fixed budget.
Suppose you can afford either:
- two premium tyres
or - four lower-priced tyres.
Don't make that decision based on quantity or brand category alone. First determine how many tyres actually need replacement.
Then compare suitable tyres according to:
- correct size
- load index
- tyre speed rating
- EU tyre label wet-grip and efficiency information
- seasonal requirements
- vehicle requirements
- price
- your driving needs
TyreSavings carries tyres across multiple price points, which means you can compare options in our budget vs premium tyres guide in your required size before deciding.
If only two tyres require replacement, buying four cheaper tyres isn't automatically better value. Likewise, if all four genuinely require replacement, buying only two premium tyres doesn't solve the need for the remaining pair.
What If All Four Tyres Are Close to the Legal Tread Limit?
In the UK, cars and light trailers must have at least 1.6 mm of tyre tread depth across the central three-quarters of the breadth of the tyre and around its entire circumference.
However, you don't need to wait until a tyre reaches the legal minimum before considering replacement.
If all four tyres are heavily worn or approaching replacement at similar rates, it may be practical to compare the cost of replacing all four at the same time.
Tyre condition matters too. Tread depth isn't the only reason a tyre may require attention.
Can Uneven Tyre Wear Change the Decision?
Absolutely.
If two tyres are significantly more worn than the others, it's worth asking why before simply fitting four new tyres.
Uneven or excessive wear can be associated with factors such as:
- incorrect tyre pressure
- wheel alignment issues
- suspension problems
- driving habits
- vehicle setup
If the underlying cause isn't addressed, your new tyres could also wear unevenly. TyreSavings has a separate guide explaining what can cause excessive or uneven tyre wear and what checks to make.
Should You Get Wheel Alignment When Buying Four New Tyres?
Four new tyres don't automatically mean your wheel alignment needs adjustment.
However, if the old tyres show unusual or uneven wear, the vehicle pulls to one side, the steering wheel sits off-centre or there are other alignment symptoms, having the alignment checked may be sensible.
Correcting an alignment problem can help prevent abnormal wear on the new tyres. See our guides on wheel alignment warning signs and wheel alignment and wheel balancing for more information.
Does Buying Four Tyres Save on Fitting Costs?
It can depend entirely on how the tyre retailer and fitter structure their tyre fitting costs.
Some tyre prices may already include specified fitting services. Other services or charges may be separate.
Don't assume that fitting four tyres costs the same as fitting two, or that a four-tyre purchase automatically attracts cheaper fitting.
Compare the actual total shown when purchasing. The number that matters is not simply:
price per tyre
but:
total cost of getting the required tyres fitted to your car.
What Should You Check Before Ordering Four Tyres?
Before clicking "buy", ask yourself five questions:
- Do all four tyres actually need replacing? Check tread depth, condition and damage.
- How soon will the remaining tyres need replacement? If the other pair is close to needing replacement, doing all four together may be worth considering.
- Is there a genuine saving? Compare the actual total for two versus four. Don't assume.
- Does my vehicle have special requirements? Check manufacturer recommendations, particularly for certain AWD and 4WD vehicles.
- Am I replacing good tyres just to obtain a discount? If so, calculate whether the discount actually compensates for the remaining life you're giving up.
How to Compare the Cost on TyreSavings
TyreSavings makes this decision easier because you can start with the tyres that actually fit your vehicle.
- Step 1: Enter Your Registration or Tyre Size
Find tyres compatible with your vehicle. - Step 2: Compare Brands and Price Points
Look at suitable budget, mid-range and premium options rather than starting with one particular manufacturer. - Step 3: Compare the Cost for the Number You Need
Check what buying two or four suitable tyres will actually cost. - Step 4: Look for Applicable Offers
If a current promotion is available, check its conditions rather than assuming every four-tyre purchase receives a discount. - Step 5: Consider the Condition of Your Existing Tyres
A lower four-tyre price isn't a saving if you're unnecessarily throwing away substantial usable tyre life. - Step 6: Arrange Local Fitting
Once you've selected your tyres, choose an available participating fitter and arrange your fitting.
So, Is It Cheaper to Buy Four Tyres Together?
Sometimes, but not automatically.
Sometimes, but not automatically.
Buying four tyres together may make financial sense when all four require replacement, the remaining pair will need replacing soon, a genuine multi-tyre promotion is available, or completing everything in one fitting visit offers worthwhile convenience or savings.
But buying four isn't good value simply because the price per tyre is slightly lower.
If two of your existing tyres still have substantial usable life, replacing them prematurely could cost more than any multi-buy saving.
The smarter approach is:
Check what needs replacing → compare the actual cost of two versus four → account for fitting and offers → check your vehicle requirements → buy the number of tyres you genuinely need.

Frequently Asked Questions
1. Is it cheaper to buy four tyres instead of two?
Not necessarily. The price per tyre may be the same regardless of quantity unless a particular promotion or pricing arrangement applies. Compare the total fitted price and consider whether all four tyres actually require replacement.
2. Do tyre shops give discounts for buying four tyres?
Some retailers, manufacturers or fitters may periodically offer promotions involving multiple tyres, but this isn't universal. Check the current offer and its terms before purchasing.
3. Should I replace all four tyres at the same time?
It depends on the condition of the tyres, the vehicle and manufacturer recommendations. If all four are similarly worn, replacing them together may make sense. If two remain serviceable, replacing four may be unnecessary.
4. Is it better to replace tyres in pairs?
Replacing tyres in pairs is common, but the appropriate approach depends on tyre condition, vehicle requirements and drivetrain. Follow vehicle-manufacturer guidance and seek professional advice if you're uncertain.
5. Should I buy four budget tyres or two premium tyres?
First determine how many tyres actually require replacement. Then compare suitable tyres according to specification, label information, driving requirements and price. Neither four budget tyres nor two premium tyres are automatically the better purchase.
6. Can I replace only one tyre?
In some circumstances, yes. However, tread differences, the opposite tyre's condition, vehicle drivetrain and manufacturer requirements can affect whether a single-tyre replacement is appropriate.
7. Do I need wheel alignment after replacing all four tyres?
Not automatically. However, if your old tyres showed uneven wear or your vehicle has symptoms of poor alignment, having the alignment checked may be appropriate.
