The Mazda CX-5 is one of Australia’s best-selling medium SUVs, and in July 2026 Mazda launched an all-new third-generation model — longer, with all-wheel drive standard across every grade. This guide covers the tyre sizes, wheel specifications, pressures and spare-wheel setup for the CX-5 as sold in Australia, including the large installed base of the previous (2017–2025) model that shares the same core fitment. Every figure here is a 2026 guide: the tyre placard in your driver’s door jamb is the final word for your exact build.

What tyre size does a Mazda CX-5 take?

CX-5 tyre size depends on the grade and its wheel diameter. Lower grades wear 17-inch wheels and taller-profile tyres; higher grades step up to 19-inch wheels with a lower profile. The core fitments have carried across the second and third generations, so the table below applies to recent Australian CX-5s — but check your placard, because Mazda can revise a fitment within a model year.

Grade (third gen, 2026–)	Tyre size	Wheel
Pure	225/65R17 102V	17×7J alloy
Evolve	225/65R17 102V	17×7J alloy
Touring	225/55R19 99V	19×7J alloy
GT SP	225/55R19 99V	19×7J alloy
Akera	225/55R19 99V	19×7J alloy

The two sizes are designed to roll at almost the same overall diameter, so your speedo stays honest whichever grade you own. If you want to understand why the numbers differ but the rolling diameter doesn’t, see our guide to aspect ratio and rolling diameter. The letters after the size are the load index (102 or 99) and speed rating (V) — never fit a replacement below the placard load index.

What are the CX-5 wheel specs (PCD, bore and offset)?

If you’re buying aftermarket or second-hand wheels, four numbers have to match: bolt pattern, centre bore, offset and width. For the CX-5 they are:

Bolt pattern (PCD)	5×114.3
Centre bore	67.1 mm (hub-centric)
Factory offset (ET)	approx. +45 to +50
Wheel fastener	M12×1.5 nut
Wheel-nut torque	per handbook (commonly ~110–130 Nm)

The hub is hub-centric at 67.1 mm, which means the wheel locates on the hub spigot, not the studs. Fit a wheel with a larger bore and you’ll need hub-centric rings to stop vibration — this is the single most common cause of a “new wheels, now it shakes” complaint. For the difference between hub-centric and lug-centric fitment, and how to measure a bolt pattern yourself, see hub-centric vs lug-centric and bolt pattern and PCD explained. Always torque wheel nuts to the handbook figure with a torque wrench, not a rattle gun, and re-torque after about 100 km.

What tyre pressure should a CX-5 run?

The correct cold pressure is on the placard inside the driver’s door jamb — typically in the low-to-mid 200s of kPa (around 33–35 psi) for the 225/65R17, and often a little higher for the 19-inch 225/55R19. Mazda usually lists a higher “loaded” or “high-speed” figure as well. Set pressures cold (before driving), use the placard, and don’t chase the much higher number moulded on the tyre sidewall — that’s a maximum, not a recommendation. Our guide to placard vs sidewall pressure explains why.

Bump pressures up for a full load of passengers and luggage, or before towing — the CX-5 is rated to tow up to around 1,800 kg braked (third gen), so a loaded tow setup benefits from the placard’s higher-load figure. Check pressures at least monthly; see how often to check.

Does the Mazda CX-5 come with a spare wheel?

Most Australian CX-5s carry a temporary space-saver spare (a T155/80R17) under the boot floor rather than a full-size wheel. A space-saver gets you to a tyre shop, but it’s speed- and distance-limited — see how far and how fast you can drive on one. Check your own boot floor, because fitment can vary by grade and build year, and confirm the spare’s pressure is topped up (space-savers run high, often around 420 kPa / 60 psi). If a full-size spare matters to you, check our list of cars that still come with a full-size spare.

Does AWD change how I buy tyres?

Yes — and it matters more on the third-generation CX-5 because all-wheel drive is now standard across every grade. On an AWD vehicle, mismatched tyre circumferences force the centre coupling and differentials to work constantly, which generates heat and wear. The practical rules: keep all four tyres the same brand, model and size; replace in sets where possible; and keep tread depths close. See do AWD cars need all four replaced together, the tread-depth tolerance that protects your diff, and whether you can mix sizes on an AWD. Regular rotation also keeps wear even.

Can I plus-size or change wheels on a CX-5?

You can, within limits. Staying close to the factory rolling diameter keeps your speedo accurate and keeps you legal — most states allow only a small variation unless the change is engineered. Going from 17s to 19s (or fitting aftermarket 18s or 20s) changes ride comfort, road noise and the cost of replacement rubber. Our plus-sizing a medium SUV guide covers the practical limits, and what bigger wheels and tyres cost sets expectations on price. Whatever you fit, don’t drop below the placard load index, and keep the speed rating at or above factory.

What are the best tyres for a CX-5 in Australia?

The CX-5 is a road-biased medium SUV, so most owners are choosing between quiet touring tyres, long-wearing tyres and budget options — not off-road rubber. Match the choice to your driving:

• Mostly city and highway commuting: quiet tyres for a medium SUV or fuel-efficient options.
• High kilometres, value focus: long-lasting medium-SUV tyres or best budget tyres.

When it’s time to replace, use the six signs beyond tread depth and the realistic kilometre expectations by tyre type. Australia’s legal minimum tread is 1.5 mm in every principal groove — but wet grip falls off well before that, so plan to replace nearer 3 mm. Check the DOT date code too, because UV and heat age rubber whatever the tread.

How much does it cost to replace CX-5 tyres in Australia?

Expect the 19-inch 225/55R19 to cost noticeably more than the 17-inch 225/65R17 — lower-profile, larger-diameter tyres are dearer to buy and there’s less rubber between your rim and a pothole. As a rough 2026 guide, a set of four mid-range tyres for the 17-inch grades is typically cheaper per corner than for the 19-inch grades, but the exact figure depends on brand, tier and where you shop, so get a live quote. Because the current CX-5 is all-wheel drive, replacing in matched sets is the sensible default, which makes the per-tyre price worth comparing properly — see cost per kilometre for how to compare tyres beyond the sticker price, and why the cheapest quote isn’t always the cheapest tyre. It’s also worth knowing what’s included in a fitting price so you can read a quote correctly.

How the CX-5 compares to its key rivals on tyre cost and setup is worth a look if you’re cross-shopping: see our guides to the Toyota RAV4, Mitsubishi Outlander, Hyundai Kona and Kia Sportage.

Frequently asked questions

What size tyres are on a Mazda CX-5?

17-inch grades (Pure, Evolve) use 225/65R17; 19-inch grades (Touring, GT SP, Akera) use 225/55R19. Confirm against your door placard.

What is the Mazda CX-5 bolt pattern?

5×114.3, with a 67.1 mm hub-centric centre bore and M12×1.5 wheel nuts. Factory offset is roughly +45 to +50.

Does the CX-5 have a full-size spare?

Most Australian CX-5s carry a temporary space-saver under the boot floor, not a full-size spare. Check your own boot and keep the spare inflated to its (high) placard pressure.

What tyre pressure should I run in a CX-5?

Use the cold pressure on the driver’s door placard — typically around 33–35 psi for the 17-inch tyre, often a little higher on 19s and when loaded or towing. The sidewall number is a maximum, not the recommendation.

Is the new CX-5 all-wheel drive?

Yes. The third-generation CX-5 (on sale in Australia from July 2026) is all-wheel drive on every grade, which makes keeping all four tyres matched for brand, size and tread depth more important.
