The Kia Sportage is one of Australia’s best-selling medium SUVs, and the current fifth-generation model (the NQ5, on sale here since late 2021) spans four main grades — S, SX, SX+ and GT-Line — plus petrol, diesel and hybrid drivetrains. That spread means there is no single “Sportage tyre size”: the number on your door placard depends on which grade and wheel package you bought. This guide pulls the fitment details together for Australian-delivered cars, explains the wheel specs that actually matter when you replace rubber, and points you to the right tyre for how you drive.

Every figure below is a 2026 guide. Kia revises wheel packages across model years and running changes, so before you buy, confirm against the tyre placard on your driver’s door jamb and the size moulded into your current tyre sidewall.

What tyre sizes does the Kia Sportage use in Australia?

Australian Sportage grades step up in wheel diameter as you move up the range. The base S rides on 17-inch alloys, the SX on 18s, and both the SX+ and GT-Line on 19s. The matching tyre sizes commonly fitted are set out below.

Sizes vary by model year and running change. The 235/55R19 fitment on higher grades is confirmed on current Australian specification; the 17- and 18-inch tyre sizes are the usual factory fitments and should be checked against your placard. Note that overseas Sportage brochures list different metric sizes (for example 215/65R17 or 235/50R19) — those are not the Australian fitments.

All three sizes are engineered to keep a near-identical rolling diameter, so your speedometer reads correctly whichever grade you own. If you ever cross-shop sizes, keep the overall diameter within a few per cent of standard. For the full breakdown of what the numbers mean, see our guide to reading a tyre sidewall and our note on aspect ratio.

What are the Kia Sportage wheel specs (PCD, bore, offset)?

When you buy aftermarket wheels or a second set, four numbers have to match: bolt pattern, centre bore, offset and load rating. For the current Sportage:

The 5×114.3 pattern is common across medium SUVs, which is why a Sportage can look like it shares wheels with a RAV4, CX-5 or Outlander. But the centre bore and offset still have to line up — a wheel with the right studs but the wrong bore will sit off-centre and vibrate. Our explainer on bolt pattern and PCD and on hub-centric fitment covers how to measure and match these properly. Confirm your exact offset and torque in the owner’s handbook before fitting anything aftermarket.

What tyre pressures should a Kia Sportage run?

Set your Sportage to the cold inflation pressures printed on the tyre placard on the driver’s door jamb — not to the maximum figure moulded on the sidewall. As a guide, current Sportage grades sit around 2.4 bar (about 35 psi) front and rear for normal use, with a higher figure specified for full loads. “Cold” means before you’ve driven more than a kilometre or two, because heat raises pressure.

Your exact numbers depend on wheel size and whether the car is laden, so the placard is the authority — we explain why in placard pressure vs sidewall maximum. The Sportage is fitted with a tyre pressure monitoring system; if a light appears in cold weather it is often just the temperature drop, as covered in why your pressure light comes on in the cold. Check pressures at least monthly — see how often you should check.

Does the Kia Sportage have a spare wheel?

Most Australian Sportage grades are supplied with a temporary space-saver spare under the boot floor, though this can vary by grade, drivetrain and model year — hybrid variants in particular sometimes substitute a tyre mobility (repair) kit where the battery hardware occupies the well. Lift your boot floor and check what your car actually carries before you need it.

A space-saver is a get-you-going item only: observe the speed and distance limits on its label (generally no faster than 80 km/h and only as far as the nearest tyre shop). Our guides to space-saver spares and repair kits vs spare wheels explain the trade-offs, and don’t forget that the spare’s own pressure is the number everyone forgets to check.

How much do Kia Sportage tyres cost in Australia?

Replacement cost climbs with wheel diameter — the 19-inch tyres on an SX+ or GT-Line cost noticeably more than the 17s on a base S, and they’re harder to find in budget brands. As a 2026 guide only, fitted prices per tyre tend to fall roughly in these bands; always get a live quote for your exact size.

Prices like these are why many owners of higher grades reconsider a premium tyre at the 19-inch size. Compare quotes across chains — see our reviews of Bob Jane T-Marts, Tyrepower and mycar, and use our method for cost per kilometre rather than sticker price alone. Watch for the usual hidden fees on a tyre quote.

What are the best replacement tyres for a Kia Sportage?

The Sportage is a road-focused family SUV, so the right replacement is a quality highway or touring tyre — there’s no need for anything aggressive. Match the choice to what bothers you most:

• Quiet, comfortable commuting: a premium touring tyre pays off at the 18- and 19-inch sizes. See best quiet tyres for a medium SUV.
• Value without nasty compromises: a strong mid-tier brand. See best budget tyres for a medium SUV.
• Fuel saving (and EV-like efficiency on the hybrid): a low-rolling-resistance tyre. See best fuel-efficient tyres for a medium SUV.
• Maximum life on high-kilometre cars: see best long-lasting tyres for a medium SUV.

Whatever you choose, don’t drop below the load index on your placard, and replace in pairs (same axle) at minimum. Australia’s legal minimum tread is 1.5 mm — not the 1.6 mm you’ll see quoted overseas — but wet grip falls off well before that, so plan to replace nearer 3 mm.

Can you plus-size or fit different wheels on a Sportage?

Yes, within limits. Staying on the 5×114.3 / 67.1 mm pattern and keeping rolling diameter close to standard, you can move between the factory 17-, 18- and 19-inch fitments. Going bigger than factory firms up the ride and can nudge your speedo and insurance position — our guide to plus-sizing a medium SUV covers the practical limits, and how tyre size affects your speedo explains the accuracy side.

Down-sizing to the 17-inch fitment (where it clears the brakes) is a popular move for ride comfort and cheaper rubber, and it’s the smarter direction on rough regional roads. If you fit aftermarket wheels, keep them hub-centric to 67.1 mm or use correctly sized spigot rings, and have the alignment checked afterwards — the difference between alignment and balancing is set out in this guide.

Frequently asked questions

What size tyres does a Kia Sportage take?

Australian grades commonly run 235/65R17 (S), 235/60R18 (SX) and 235/55R19 (SX+ and GT-Line). Confirm your exact size on the door-jamb placard and your current sidewall.

What is the bolt pattern on a Kia Sportage?

The current NQ5 Sportage uses a 5×114.3 mm bolt pattern with a 67.1 mm centre bore and M12×1.5 studs. PCD alone doesn’t guarantee a fit — the bore and offset must match too.

Does the Kia Sportage come with a full-size spare?

No — most Australian Sportage grades carry a temporary space-saver spare under the boot floor, and some variants (particularly hybrids) use a tyre repair kit instead. Check what your specific car has.

What tyre pressure should I run in my Sportage?

Follow the cold pressures on your tyre placard — as a guide, around 2.4 bar (about 35 psi) for normal use, higher when fully loaded. The placard is the authority, not the sidewall maximum.

Can I fit 19-inch wheels to a lower-grade Sportage?

Generally yes, if you keep the 5×114.3 / 67.1 mm fitment, the correct offset and a tyre that preserves rolling diameter (235/55R19). Expect a firmer ride and dearer tyres; have the alignment checked afterwards.
