Quick answer: The current Tesla Model Y (Juniper) runs 255/45R19 tyres on the standard 19-inch wheel and 255/40R20 on the 20-inch option, with a staggered setup on Performance. The bolt pattern is 5×114.3 with a 64.1 mm hub-centric bore. There is no spare — just a repair kit — and the car uses high-load-index, acoustic-foam tyres.

What tyre size does a Tesla Model Y use?
The Model Y sold today is the updated “Juniper” version, which arrived in Australia in 2025 across RWD, Long Range and Performance variants. Factory fitments are tied to the wheel you choose rather than the trim:
| Wheel | Rim | Tyre size |
|---|---|---|
| 19-inch (standard, “Crossflow”) | 19×9.5J | 255/45R19 104W XL |
| 20-inch (optional) | 20×9.5J | 255/40R20 (confirm on placard) |
| 21-inch Performance (staggered) | front/rear differ | front 255/35R21, rear 275/35R21 (confirm) |
Reading 255/45R19 104W XL: 255 mm wide, sidewall 45% of width, 19-inch rim, load index 104 (high, for the car’s weight), W speed rating and XL (Extra Load) construction. The XL and the high load index are not optional extras — they are there because an electric SUV is heavy. See how to read a tyre sidewall for the full decode, and how to read your car’s tyre placard. These are 2026 guide figures; the 20-inch and Performance sizes in particular change between model years, so confirm on your door placard.
What are the Model Y wheel specs (PCD, offset and bore)?
| Bolt pattern (PCD) | 5×114.3 |
| Centre bore | 64.1 mm (hub-centric) |
| Offset (ET) | approx. +45 (19-inch) |
| Lug thread | M14 × 1.5 |
| Wheel nut torque | approx. 160–175 Nm (confirm with Tesla’s figure) |
The 5×114.3 pattern is shared with many Japanese and Korean SUVs, but the Model Y’s 64.1 mm hub-centric bore and high required load rating mean you cannot simply bolt on any 5×114.3 wheel. Get the bore and load rating right or you will chase vibration and risk an under-rated fitment. The basics are in bolt pattern and PCD explained and centre bore explained. The Model Y also uses TPMS sensors, so factor those in if you buy a second set of wheels for touring.
What tyre pressures should a Model Y run?
Model Y placard pressures are higher than a typical petrol SUV — commonly around 42 psi cold — to carry the weight and to protect range. Always set to the figure on the driver’s door placard (Tesla also shows it in the touchscreen service menu), cold, and do not “round down” to what feels normal for a petrol car. Running low on a heavy EV accelerates wear dramatically and eats range. For why EVs sit higher, see do EVs need higher tyre pressures than petrol cars? and the general rule in placard pressure vs sidewall maximum.
Does the Model Y have a spare?
No. Like almost every EV, the Model Y comes with no spare wheel — there is room for a repair/inflation kit and Tesla’s mobile and roadside support instead. A sealant kit handles a small tread puncture but will not fix a sidewall cut, a blowout, or a wheel damaged by a pothole, and the staggered Performance tyres cannot be rotated to limp home. Read tyre repair kits vs spare wheels so you know the limits before you are stranded. Many owners carry a quality plug kit and a 12-volt compressor as backup.
Why EV tyres matter more on a Model Y
Three things make tyre choice more consequential on a Model Y than on an equivalent petrol SUV. First, weight and instant torque wear tyres faster — see why EV tyres wear out faster. Second, with no engine noise, tyre roar dominates the cabin, which is why the factory tyres use acoustic foam liners (Tesla’s OEM tyres are marked with the makers’ foam technologies). Third, the load index is critical on a heavy EV. If you want the detail: do you need EV-specific tyres?, foam-filled acoustic tyres and load index requirements for heavy EVs.
Best replacement tyres for a Model Y
When the factory tyres wear out — often sooner than owners expect — replace like with like: an EV-suitable tyre with the correct load index, XL construction and, ideally, an acoustic foam liner for cabin quiet. Dropping to a cheaper tyre without foam or with a lower load rating saves money up front but costs you noise, range and possibly compliance. For a quiet-focused shortlist see best quiet tyres for an electric car. If you also run a rival family SUV, the Toyota RAV4 guide is a useful comparison point.
How much do Model Y tyres cost in Australia?
As a 2026 guide, Model Y tyres run roughly $300–$500+ a corner fitted for the 19-inch size in a quality EV-rated tyre, with 20-inch and staggered 21-inch Performance rubber costing more again. Acoustic-foam, high-load tyres sit at the pricier end — that is the EV premium. Get a live quote and make sure the shop quotes a tyre with the correct load index and speed rating. The Australian legal minimum tread is 1.5 mm (the 1.5mm rule), but a heavy EV loses wet grip early, so plan to replace nearer 3 mm.
For current specifications, Tesla’s own Model Y page and independent fitment references are useful cross-checks — but your door placard and touchscreen are the final word on sizes and pressures.
Bottom line: the Model Y needs 255/45R19 (or the 20-inch/Performance sizes), 5×114.3 / 64.1 mm wheels, ~42 psi, and a high-load, foam-lined EV tyre. There is no spare, so carry a plug kit and respect the load rating — EVs are unforgiving of the wrong tyre.
Frequently asked questions
What size tyres does a Tesla Model Y take?
The current Juniper runs 255/45R19 on the standard 19-inch wheel, 255/40R20 on the 20-inch option, and a staggered setup (around 255/35R21 front, 275/35R21 rear) on Performance. Confirm on your placard.
What is the bolt pattern on a Tesla Model Y?
5×114.3 with a 64.1 mm hub-centric centre bore and M14 × 1.5 lugs. The pattern is common, but the bore and high load-rating requirement mean not every 5×114.3 wheel is suitable.
Does the Tesla Model Y have a spare tyre?
No. It comes with a repair/inflation kit and Tesla roadside support, not a spare. A sealant kit cannot fix a sidewall cut or blowout, so many owners carry a plug kit and compressor.
What tyre pressure should a Model Y run?
Typically around 42 psi cold — higher than a petrol SUV — but set it to your door placard figure. Correct pressure protects both tyre life and driving range.
Why do Tesla Model Y tyres wear out so fast?
The car’s weight and instant torque are hard on tyres. Keeping pressures at the placard figure, rotating regularly (where not staggered) and choosing an EV-rated tyre all help extend life.
