Vauxhall Agila Tyre Size: Complete Guide by Model and Year

Finding the correct Vauxhall Agila tyre size sounds simple until we start looking at different engines, generations, wheel sizes, and trim levels. One Agila may leave the factory on compact 14-inch tyres, while another can use wider 15-inch rubber.

That difference matters.

Using the correct tyre size helps maintain predictable handling, braking performance, ride comfort, fuel economy, and speedometer accuracy. More importantly, replacing tyres with an unsuitable size can create clearance issues or change the way the car behaves on the road.

The Vauxhall Agila was produced across two main generations, and several tyre sizes were used during its life. As a quick reference, the sizes most commonly associated with the model include 155/65 R14, 165/60 R14, 165/70 R14, and 185/60 R15. Michelin also lists 155/65 R14 and 165/60 R14 for earlier Agila versions, while Vauxhall's second-generation owner's manual specifies 165/70 R14 and 185/60 R15 depending on engine and equipment.

Let's break everything down.

Vauxhall Agila Tyre Size at a Glance

The exact tyre fitted to an Agila depends primarily on its generation and specification.

These sizes should be treated as a guide rather than a substitute for checking the specific car.

Vauxhall itself recommends identifying the tyre code fitted to the vehicle and checking the technical section of the owner's manual or the tyre information label on the vehicle.

Vauxhall Agila Tyre Size by Generation

Understanding which generation we have is the easiest way to narrow down the correct tyre.

Vauxhall Agila A Tyre Size: 2000–2007

The original Vauxhall Agila was a small, tall city car designed around relatively narrow tyres.

Two of the most common tyre sizes are:

• 155/65 R14 75T
• 165/60 R14 75T

Michelin lists both sizes for several early Agila versions, including the 2003 1.2 models.

For some 1.3 CDTi applications, a higher load rating such as 165/60 R14 79T may be specified.

This is an important reminder that we shouldn't look only at the three main dimensions. The load and speed ratings matter too.

Vauxhall Agila B Tyre Size: 2008–2015

The second-generation Agila introduced a different platform and new wheel-and-tyre combinations.

The two key sizes are:

• 165/70 R14
• 185/60 R15

Vauxhall's Agila owner's manual lists these sizes in its official tyre-pressure tables for the K10B, K12B and D13A engines.

Generally, the narrower 165 tyre was associated with smaller wheels and certain versions, while 185/60 R15 tyres appeared on models equipped with 15-inch wheels.

Vauxhall Agila 14-Inch Tyre Size

Fourteen-inch wheels appear throughout much of the Agila's history, but the tyre dimensions changed between generations.

155/65 R14

This is one of the classic first-generation Agila tyre sizes.

The numbers tell us:

• 155 – tyre width in millimetres
• 65 – sidewall height as a percentage of tyre width
• R – radial construction
• 14 – wheel diameter in inches

A tyre with this specification is relatively narrow and has a reasonably generous sidewall.

That combination suits a lightweight city car nicely because it can provide good ride comfort and relatively low rolling resistance.

165/60 R14

The 165/60 R14 offers a slightly wider footprint while maintaining a similar overall diameter.

It was also used on first-generation Agila models.

Compared with a 155/65 R14, we get:

• 10 mm more nominal width
• A slightly lower-profile sidewall
• A subtly different steering feel
• Similar overall rolling diameter

However, we shouldn't automatically swap between the two without confirming that the alternative size is approved for our particular version.

165/70 R14

When the second-generation Agila arrived, 165/70 R14 became an important standard size.

The August 2009 Vauxhall owner's manual specifically lists 165/70 R14 in its tyre-pressure data.

Because of its taller 70-profile sidewall, this tyre generally prioritises comfort and everyday usability over sporty steering response.

For a small urban car, that makes perfect sense.

Vauxhall Agila 15-Inch Tyre Size

The principal 15-inch tyre size found on the later Agila is:

185/60 R15

This tyre is considerably wider than the standard 165-width option.

Vauxhall's manual confirms 185/60 R15 as an approved tyre size for second-generation vehicles covered by the document.

What Does 185/60 R15 Mean?

Breaking the size down:

185 means the tyre has a nominal width of 185 mm.

60 means the sidewall height is 60% of that width.

R means radial construction.

15 means it fits a 15-inch wheel.

The additional width can provide a broader contact patch, although real-world grip depends heavily on tyre compound, tread design, temperature, road conditions, and tyre condition.

Which Vauxhall Agila Tyre Size Do I Need?

Before ordering tyres online, we recommend checking the car itself.

There are several reliable places to look.

Check the Existing Tyre Sidewall

Look at the side of one of the tyres.

You may see something such as:

185/60 R15 84H

The first part gives us the basic tyre dimensions.

The final characters represent the tyre's load and speed ratings.

Check the Driver's Door Pillar

On later Agilas, tyre information can also be found on a vehicle label.

Vauxhall states that tyre-pressure information may appear on the front door pillar and directs owners to the vehicle manual for the correct specifications.

Check the Owner's Manual

This is especially important if the car currently has aftermarket wheels.

Imagine buying a used Agila with 16-inch alloys installed by a previous owner. Reading the sidewall tells us what is fitted now—not necessarily what Vauxhall originally approved.

The manual gives us a much better reference point.

Vauxhall Agila Tyre Pressure

Tyre size and tyre pressure are closely connected.

We shouldn't assume every Agila tyre requires the same pressure.

For the second-generation model, Vauxhall published different recommendations depending on engine, tyre size and vehicle load.

Agila 165/70 R14 Tyre Pressure

For petrol versions using the K10B or K12B engines and 165/70 R14 tyres, the manual lists the following comfort pressures with up to three people:

• Front: 2.3 bar / 33 psi
• Rear: 2.3 bar / 33 psi

With a full load, the listed pressures rise to:

• Front: 2.5 bar / 36 psi
• Rear: 2.8 bar / 41 psi

The diesel D13A version uses different figures in some conditions, so checking the specific vehicle remains important.

Agila 185/60 R15 Tyre Pressure

For petrol K10B and K12B versions fitted with 185/60 R15 tyres, Vauxhall lists comfort pressures of:

• Front: 2.3 bar / 33 psi
• Rear: 2.1 bar / 30 psi

Under full load:

• Front: 2.3 bar / 33 psi
• Rear: 2.6 bar / 38 psi

Again, diesel specifications can differ.

Always Check Pressure When the Tyres Are Cold

Vauxhall recommends checking pressures with cold tyres and advises regular checks as well as checking before longer journeys.

That is worth remembering.

Driving heats the tyre and increases its internal pressure, so checking immediately after a motorway journey may produce a misleading reading.

Vauxhall Agila Spare Tyre Size

Some second-generation Agilas use a temporary spare rather than a full-sized wheel.

Vauxhall lists:

T125/70 R15

The pressure specified for this temporary spare is 4.2 bar / 61 psi in the referenced owner's manual.

The letter T tells us this is a temporary-use tyre.

It should not be treated like a normal road tyre for everyday driving.

How to Read a Vauxhall Agila Tyre Size

Tyre codes look like alphabet soup until we understand the formula.

Let's take:

185/60 R15 84H

185 – Tyre Width

The first number represents nominal width in millimetres.

In this example, that's 185 mm.

60 – Aspect Ratio

The second number represents the sidewall height as a percentage of tyre width.

A lower number generally means a shorter sidewall.

R – Construction

The R indicates radial construction, which is standard on modern passenger cars.

15 – Wheel Diameter

This tells us the diameter of the wheel that the tyre is designed to fit.

A 15-inch tyre cannot simply be installed on a 14-inch wheel.

84 – Load Index

The load index represents the maximum rated load the tyre can support under specified conditions.

Always use tyres with an appropriate load rating for the vehicle.

H – Speed Rating

The final letter indicates the tyre's speed category.

Vauxhall's manual explains these markings and lists common speed codes such as T, H and V.

Can We Fit Wider Tyres to a Vauxhall Agila?

Technically, alternative wheel and tyre combinations may be possible.

But “will it physically fit?” and “is it appropriate?” are two different questions.

Changing tyre width or wheel diameter affects several variables:

• Overall tyre diameter
• Wheel clearance
• Steering clearance
• Ride quality
• Speedometer reading
• Handling characteristics
• Wheel offset requirements
• Load capability

That's why fitting wider tyres isn't as simple as choosing something that looks better.

Keep the Rolling Diameter Close to Standard

When changing wheel diameter, we normally want the overall tyre diameter to remain reasonably close to the original specification.

Why?

Because the car calculates road speed based on wheel rotation.

A significantly larger or smaller rolling circumference can alter the relationship between wheel speed and actual road speed.

165/70 R14 vs 185/60 R15 on the Vauxhall Agila

These are two particularly relevant tyre sizes for the later Agila.

The 165/70 R14 setup makes plenty of sense for everyday urban driving.

The taller sidewall can help absorb imperfections, making potholes and rough roads less dramatic.

The 185/60 R15 setup gives us a wider tyre and larger wheel while maintaining an overall diameter appropriate for the vehicle when specified by the manufacturer.

Neither size is universally “better.”

The correct choice depends on which setup the particular Agila was designed to use.

155/65 R14 vs 165/60 R14 on the Agila A

The first-generation Agila presents a similar choice.

The 155/65 R14 is narrower, while the 165/60 R14 provides additional width.

Michelin identifies both as tyre sizes associated with early Vauxhall Agila models.

For normal replacement purposes, we'd usually stick to the specification already approved for the vehicle rather than changing dimensions unnecessarily.

Best Tyres for a Vauxhall Agila

There isn't one universally perfect tyre.

Instead, we should choose according to how the car is used.

For Mostly City Driving

Look for tyres that prioritise:

• Low road noise
• Predictable wet braking
• Comfortable ride
• Reasonable rolling resistance
• Good durability

The Agila is primarily a small city car, so buying an ultra-performance tyre rarely makes much sense.

For High Annual Mileage

If we spend plenty of time on A-roads and motorways, durability becomes more important.

A tyre that costs slightly more but lasts noticeably longer may represent better value over its lifespan.

For Wet UK Conditions

Wet performance deserves particular attention.

Tyre labels and independent tyre tests can help us compare wet braking and other characteristics within the exact tyre size we're shopping for.

Should All Four Agila Tyres Be the Same Size?

For the standard Agila configurations discussed here, the vehicle normally uses the same basic tyre dimensions on the front and rear.

That doesn't mean we should mix random tyre specifications.

Ideally, tyres across the same axle should match closely in:

• Size
• Construction
• Load rating
• Speed rating
• Tread pattern
• Wear level

Mixing significantly different tyres can create inconsistent grip characteristics, particularly in wet or emergency manoeuvres.

When Should Vauxhall Agila Tyres Be Replaced?

Tyres aren't only replaced because the tread disappears.

We should inspect them regularly for:

• Cracking
• Cuts
• Bulges
• Uneven wear
• Embedded objects
• Sidewall damage
• Abnormal vibration

Vauxhall advises checking tyre condition and pressure regularly. Its current UK maintenance guidance also references the legal UK minimum tread depth of 1.6 mm across the central three-quarters of the tyre tread.

Waiting until a tyre looks completely bald is obviously not the strategy we want.

Why Is My Vauxhall Agila Wearing Tyres Unevenly?

Uneven wear can tell us something about the car.

Wear on Both Outer Edges

This can sometimes indicate prolonged underinflation.

Wear Down the Centre

Excessive pressure may contribute to greater wear around the central area of the tread.

Wear Mainly on One Side

Wheel alignment or suspension geometry may need attention.

Patchy or Irregular Wear

Suspension components, wheel balance, tyre condition, or alignment could be involved.

Replacing the tyre without investigating the underlying cause may simply destroy another tyre.

Can We Use Winter Tyres on the Vauxhall Agila?

Yes, provided the tyre specification is suitable for the vehicle.

Interestingly, Vauxhall's second-generation manual specifically states that 165/70 R14 and 185/60 R15 can be used as winter tyre sizes for vehicles covered by that manual.

Winter tyres use compounds designed to remain more effective at lower temperatures.

For drivers living in areas that regularly experience cold conditions, ice or snow, they can offer substantial seasonal advantages.

Does Tyre Size Affect Fuel Economy?

Potentially, yes.

Tyre width, compound, construction, pressure and rolling resistance can all influence energy consumption.

A wider tyre isn't automatically dramatically less efficient, but increasing tyre width can increase rolling resistance and aerodynamic drag in some situations.

Pressure matters too.

Driving around with significantly underinflated tyres increases deformation as the tyre rolls.

Think of trying to push a bicycle with a half-flat tyre. The car experiences a less dramatic version of the same effect.

Does Tyre Size Affect Ride Comfort?

Absolutely.

The tyre itself acts as part of the suspension system.

A tall sidewall contains more air and generally provides more cushioning between the wheel and road.

That's one reason a 165/70 R14 setup can feel pleasantly forgiving.

Larger wheels combined with shorter sidewalls may provide a more direct feel, but the tyre has less sidewall available to absorb sharp imperfections.

For a city car like the Agila, comfort is often more valuable than razor-sharp steering.

Common Vauxhall Agila Tyre Size Mistakes

Buying replacement tyres is simple when we avoid a few common mistakes.

Ordering by Model Name Alone

“Vauxhall Agila tyres” isn't specific enough.

Generation, engine, trim and wheel size can matter.

Ignoring the Load Index

Two tyres may have identical physical dimensions but different load ratings.

Confusing 14-Inch and 15-Inch Sizes

A 185/60 R15 tyre requires a 15-inch wheel.

It won't fit a 14-inch rim.

Copying Another Agila

The neighbour's Agila may look identical while using another approved wheel configuration.

Check the actual vehicle.

Assuming the Current Wheels Are Original

Used cars often come with aftermarket wheels.

This is why checking the owner's manual and vehicle tyre label remains so important.

Our Vauxhall Agila Tyre Size Checklist

Before buying new tyres, we'd run through this simple checklist:

1. Check the tyre size printed on the current sidewall.
2. Confirm the wheel diameter.
3. Check the driver's door-pillar tyre label where fitted.
4. Consult the relevant Vauxhall owner's manual.
5. Confirm the load index.
6. Confirm the speed rating.
7. Check whether the wheels are original.
8. Compare front and rear specifications.
9. Check tyre pressures after installation.
10. Recheck pressure periodically when tyres are cold.

Five minutes of checking can prevent an expensive ordering mistake.

Final Thoughts on Vauxhall Agila Tyre Sizes

The Vauxhall Agila tyre size depends mainly on which generation and specification we own.

Earlier Agila A models commonly use 155/65 R14 or 165/60 R14, while the later Agila B commonly uses 165/70 R14 or 185/60 R15.

Rather than choosing a tyre solely because an online listing says it fits an Agila, we should confirm the specification on the car and in its manual.

The correct tyre isn't merely the one that fits around the wheel.

It forms part of the vehicle's original engineering package, influencing comfort, braking, steering, efficiency and safety every kilometre we drive.

Frequently Asked Questions

What tyre size does a Vauxhall Agila use?

Common Vauxhall Agila tyre sizes include 155/65 R14, 165/60 R14, 165/70 R14 and 185/60 R15. The correct size depends on the generation, engine and wheel specification.

What is the Vauxhall Agila 2008–2015 tyre size?

The second-generation Agila uses tyre sizes including 165/70 R14 and 185/60 R15, according to Vauxhall's owner's manual.

What is the Vauxhall Agila 2000–2007 tyre size?

Common first-generation fitments include 155/65 R14 and 165/60 R14. Exact specifications can vary according to engine and version.

What tyre pressure should a Vauxhall Agila have?

Pressure varies by tyre size, engine and vehicle load. For example, Vauxhall lists 2.3 bar front and rear for certain petrol Agila B versions using 165/70 R14 tyres with up to three occupants. Always confirm the figures for the specific vehicle using the tyre label or owner's manual.

Can I put 15-inch wheels on a Vauxhall Agila?

Some second-generation Vauxhall Agilas were designed for 15-inch wheels with 185/60 R15 tyres, so 15-inch fitments certainly exist. However, we shouldn't assume that any 15-inch wheel will fit correctly. Wheel width, offset, bolt pattern, load capacity and tyre dimensions must all be compatible with the specific vehicle.
