BYD Tyre Guide: Atto 3, Seal & Sealion 7 — What Perth Owners Need to Replace Them
Three years ago, most Perth drivers had never heard of BYD. Today, the Chinese brand is the second-largest EV seller in Australia, and its vehicles; the practical Atto 3, the sharper Seal, and the family-sized Sealion 7, are a common sight in the western suburbs. If you're one of the growing number of Perth drivers behind the wheel of a BYD, you already know the ownership experience is excellent.
The question that eventually faces every BYD owner is a simpler one: where do you go for BYD tyres in Perth, and what do you ask for?
This guide covers the three most common BYD models on Perth roads, with the tyre specifications, replacement guidance, and practical advice you need.
BYD Tyres Perth: The Short Answer
|
BYD tyres aren't sold through a separate “EV-only” category — the Atto 3, Seal and Sealion 7 each use standard tyre sizes (215/55 R18, 235/50 R18, 235/45 R20 and similar, depending on variant) that must meet the correct load and speed rating for the vehicle's weight. Tyrepower West Perth stocks EV-capable options from Continental, Michelin, Hankook and Bridgestone, and recalibrates your BYD's TPMS as standard with every fitment. |
Before We Start: Why BYD Tyres Are Different from Petrol Car Tyres
If you want the full picture on why EVs make specific demands on their tyres — weight, instant torque, cabin noise — we've covered that in detail in our companion article, Do Electric Cars Need Special Tyres? What Perth EV Owners Need to Know. The short version: BYD vehicles are heavier than their petrol equivalents, deliver torque instantly, and need tyres matched to their actual load ratings. Getting this right matters for safety, wear life, and driving range.
Perth Guide to BYD Atto 3 Tyres
The Atto 3 is the car that established BYD in Australia. It's practical, well-priced, and widely regarded as the ideal first EV for Australian buyers. It's also the BYD model most likely to have owners arriving for their first tyre replacement wondering exactly what they need.
Atto 3 Tyre Sizes
The Atto 3 comes in two variants with different tyre sizes:
- Extended Range / Premium (most common on Perth roads): 215/55 R18, load rating 99V
- Standard Range Essential: 215/60 R17
The load rating matters. At 99V, the Atto 3 Extended Range tyre must support a vehicle that weighs over 1,700 kg. Fitting a tyre with a lower load rating — even if the size matches — compromises safety and accelerates wear. Always confirm against the placard on your driver's door jamb before purchasing.
The Atto 3 uses a 5×114.3 mm bolt pattern — the same as many Toyota, Honda, and Mazda vehicles — which means aftermarket wheel options are plentiful. But wheel fitment requires matching centre bore and offset as well as bolt pattern; if you're considering an upgrade, bring the car in for a proper fitment consultation.
Factory Tyres and Lifespan
Atto 3 models in Australia have typically been delivered on Continental or Atlas tyres depending on build date and variant. Factory fitment tends to last 40,000 to 55,000 kilometres under normal conditions, though Perth's summer heat and the Atto 3's torquey front-wheel-drive setup mean rotation discipline has a significant effect on that figure. Rotate every 8,000 to 10,000 kilometres — not at the default petrol car interval.
What Not to Do
Two mistakes we see regularly in our workshop with Atto 3 owners:
- Mixing tyre brands across axles: the Atto 3's traction control system is sensitive to mismatched grip profiles. Front and rear should carry the same brand and model where possible
- Ignoring the TPMS warning: the Atto 3's tyre pressure monitoring system is accurate. A warning that gets dismissed can result in premature wear, range loss, and in extreme cases, tyre failure
Atto 3 Replacement Options
Here are the tiers worth discussing with our team:
- Mid-range: Hankook Kinergy Eco 2 — quiet, good wear life, well-suited to Perth suburban commuting
- EV-capable: Continental EcoContact 6 — strong rolling resistance credentials, excellent wet weather performance for Perth's winter months
- Premium: Michelin e.Primacy — EV-optimised compound, measurable range benefit, noticeably quieter than some factory fitments
The right choice depends on how you drive, how many kilometres you cover annually, and how much you value range versus tyre longevity. Book a consultation and we'll talk it through properly.
Perth Guide to BYD Seal Tyres
The Seal is the sharper, sportier member of BYD's Australian lineup — a sedan that delivers a driving experience meaningfully different from the Atto 3's family-SUV softness. It also places meaningfully different demands on its tyres.
Seal Tyre Sizes
The Seal comes in Dynamic, Premium, and Performance variants, each with different wheel and tyre specifications. Sizes vary across the range — confirm against your door placard before purchasing any replacement tyres. Do not rely on what's currently fitted, as previous owners or dealers may have fitted alternatives.
The Seal Performance, with its higher power output and AWD configuration, places the greatest demands on tyres. For Performance owners, EV-specific tyres with reinforced sidewalls are strongly recommended — this is a car that can produce significant wheel torque, and a tyre without the right load and speed rating will wear unevenly and fail earlier than expected.
Seal Replacement Options
For everyday Premium driving in Perth:
- Continental EcoContact 6 — consistent across performance and efficiency (see the full Continental range)
- Michelin Primacy 5 — premium comfort and wet weather performance (browse the Michelin range)
For Seal Performance owners who value grip alongside efficiency:
- Continental SportContact 7 EV — performance-oriented with EV load credentials
- Michelin Pilot Sport 4S — factory-specification on many performance-oriented EVs globally
Alignment is particularly important on the Seal Performance — the AWD setup is sensitive to imbalance, and we recommend a wheel alignment check whenever tyres are replaced.
Perth Guide to BYD Sealion 7 Tyres
The Sealion 7 is the most significant BYD in Australia right now. It finished 2025 as Australia's second most popular EV behind only the Tesla Model Y, and in several months it outsold the Model Y outright. If you're a Sealion 7 owner, you're driving one of the best-selling family EVs in the country. It's worth making sure your tyres are up to the job.
Sealion 7 Tyre Sizes
- Premium (RWD): 235/50 R19 front, 255/45 R19 rear on 19-inch alloys
- Performance (AWD): 235/45 R20 on 20-inch alloys
The Sealion 7 Premium's 19-inch setup offers the more comfortable ride of the two variants. Those slightly taller sidewalls providing more cushioning over Perth's occasional rough surfaces. The Performance's 20-inch tyres offer a sportier look but reduce that compliance. For context on BYD's wheel range more broadly, see our BYD vehicle hub (including the related Sealion 6).
The Sealion 7 weighs over 2,200 kilograms. This is significantly heavy for its class. Tyre selection must account for this weight. Under-rated tyres on a 2.2-tonne vehicle will overheat under sustained load, particularly on a warm Perth day.
What Sealion 7 Owners Need to Know
Like the Tesla Model Y, the BYD Sealion 7 does not come with a spare tyre. Instead, it carries a tyre repair kit in the boot floor. This is standard for the EV segment, but it has real implications for Perth drivers.
A tyre repair kit can seal a simple puncture in the tread area. It cannot help with a sidewall blowout, a large gash, or a tyre that has been run flat. For drivers regularly travelling between Perth and the south-west, such as Margaret River, Busselton, Albany – the absence of a spare is worth taking seriously.
Options worth considering:
- Quality tyre condition maintenance: the better the tyre condition, the lower the puncture risk. Regular inspections matter more without a spare
- Third-party spare tyre kits: purpose-built space-saver spare kits for the Sealion 7 are available and designed to fit the boot floor without affecting range
- If a flat catches you out, give us a call on (08) 9322 2214 and we'll talk you through your options, including booking your vehicle in with us for new tyres.
Replacement Options — Sealion 7
- Continental EcoContact 6: available in both R19 and R20 sizes; strong EV credentials, excellent for Perth's mix of highway and suburban driving (see the Continental range)
- Bridgestone Turanza EV: quiet, efficient, well-suited to the Sealion 7's comfort-focused suspension and 2.2-tonne mass (browse Bridgestone)
- Michelin Primacy 5: premium comfort and wet weather performance; particularly relevant for Perth winters on Stirling Highway or the Graham Farmer Freeway (see the Michelin range)
What Tyrepower West Perth Does for Every BYD
BYD vehicles have specific service requirements that not every tyre shop is equipped to handle correctly. When you bring your BYD to our Troode Street workshop, here's what we do as standard:
- TPMS recalibration: BYD's tyre pressure monitoring system requires recalibration after any tyre change or rotation. We do this as a matter of course; many shops don't
- Wheel torque to specification: BYD alloys have specific torque requirements; over-tightening causes cracking. We use calibrated torque equipment on every fitment
- 3D wheel alignment check: recommended with every tyre replacement on any BYD; the combination of EV weight and torque makes alignment more important than on standard vehicles
- Complimentary Uber to your next stop: Drop your car into the shop and we can arrange an Uber to take you to your next stop while you’re tyres are being fitted.
Frequently Asked Questions
Why do my BYD tyres seem to wear faster than expected?
BYD vehicles are heavy by design – the Blade Battery adds significant mass, and heavier vehicles wear tyres faster. The fix is consistent rotation every 8,000 to 10,000 kilometres, and tyre inspections more frequently during Perth summer months.
Do I need EV-specific tyres for my BYD?
Not legally required, but strongly recommended for the Seal Performance and Sealion 7 where vehicle weight and torque output are highest. For the Atto 3 Standard Range, quality mid-range tyres from reputable brands are a reasonable choice, the key requirement is matching the correct load rating.
Can I fit aftermarket wheels on my BYD Atto 3 or Sealion 7?
Yes, both models use a 5×114.3 mm bolt pattern, which is common across many mainstream vehicles and creates wide aftermarket wheel availability. However, centre bore, offset, and load rating must all be confirmed before fitting. Come in for a fitment consultation and we'll make sure the setup is safe and compliant.
What if I get a flat and the repair kit doesn't work?
Call us on (08) 9322 2214 and we'll talk you through your options and get your BYD sorted with new tyres fitted. If your vehicle is going to be with us for a while, we can arrange a complimentary Uber to drop you off to your next location while you wait.
