BYD Great Tang: Wheel-Rim Error, EV Specs and Australian Lineup — November 12, 2026

Information checked November 12, 2026, at 12:54 p.m. in Sydney, Australian Eastern Daylight Time (AEDT, UTC+11:00; 01:54 UTC). BYD has acknowledged that some of its Great Tang, also called Da Tang, electric SUVs in China left production with their front and rear wheel rims installed in the wrong positions. In its November 11, 2026 statement, the company traced the mistake to a supplier's coding error and promised affected owners free inspections and corrections. BYD says its own testing found no effect on handling or driving safety; the number of affected vehicles and production batches has not been disclosed.

For Australians following the news, the immediate distinction is that the Great Tang is a China-market flagship, not a model currently shown on BYD Australia's consumer vehicle list. The frequently searched phrase “reverse rims” describes a manufacturing error, not an innovative wheel feature or the SUV's genuine rear-wheel-steering system. Buyers should evaluate the car's impressive China-market specifications separately from its unconfirmed local availability.

Destaques

• BYD acknowledged a front-to-rear rim installation mistake on some Great Tang EVs on November 11, 2026, and attributed it to a supplier coding error.
• BYD offers affected owners in China free inspections and rim swaps, transportation support, and a reset of the full-vehicle warranty; its no-safety-risk finding is the manufacturer's own assessment.
• The Great Tang offers seven seats, advertised China-market range of up to 950 km under the CLTC test cycle, and available rear-wheel steering; the claimed range is not an Australian WLTP rating.
• There is no confirmed Australian Great Tang launch date or local price on BYD Australia's current vehicle website.

What happened with the BYD Great Tang wheel rims?

The November 11 announcement followed owner complaints in China about staggered wheel fitment. A staggered setup deliberately uses different widths on the front and rear axles. The problem was not that the Great Tang was engineered to steer backward or that a wheel had simply been rotated during routine maintenance. Instead, some completed vehicles carried wheel rims meant for one axle on the opposite axle.

BYD said the rim subassembly supplier, Hubei Boyu Industrial, made a coding-entry error. The automaker reported correcting its coding, reviewing affected production, and adding supplier-side visual mistake-prevention checks. Its response includes invitations to designated service facilities for free inspection and professional rim repositioning, plus loaner transportation or reimbursement for travel costs. For vehicles with incorrectly fitted rims, BYD said the entire vehicle warranty period would restart from November 11, 2026.

There is an important difference between BYD's reported test conclusion and independent evidence. The company states the issue does not compromise vehicle handling or pose a driving safety risk. Owners had raised concerns about tire wear and behavior. The publicly available statement does not establish a verified incident count or detailed testing protocol, so neither a proven broader hazard nor an independently confirmed all-clear should be inferred. Reporting on the statement is available from Reuters' original November 11 report.

What does “reverse rims” mean, and why do front and rear sizes differ?

“Reverse rims” is an informal description of rims being fitted in the wrong front/rear positions, not an official BYD technology name. Owners' accounts of the 20-inch, 950-km rear-wheel-drive Great Tang version describe the intended wheel and tire pairings below. These specifications come from owner reports and should not be assumed to apply to every Great Tang trim.

The “20” specifies rim diameter in inches, while the 8 and 9 designate nominal rim width in inches. The “J” refers to the rim flange profile. Thus, both rims may look similar from outside even though one is one inch wider. The tire sidewall dimensions alone cannot establish the rim's underlying width. An owner concerned about fitment should ask an authorized technician to check wheel markings and the vehicle's exact approved specifications rather than exchanging wheels or tires at home.

Is rear-wheel steering the same as the reversed-rim problem?

No. They are separate subjects. The Great Tang's actual rear-wheel-steering system is a designed feature that can turn its rear wheels through a maximum angle of approximately seven degrees in either direction, according to BYD's official Chinese Great Tang product page. BYD advertises a 5.2-meter turning radius and a crab-walk maneuvering function. Rear-wheel steering uses control systems to change the direction of the rear tires; it does not mean reversing the rims between axles.

The SUV also advertises DiSus-A dual-chamber air suspension and road-preview damping technology. Those features address ride and maneuverability, not the manufacturing mix-up. Driver-assistance and parking systems likewise still require an attentive driver; their availability and capabilities depend on the version and market.

What are the BYD Great Tang EV's key specs and features?

BYD launched the Great Tang EV in China on June 17, 2026, as a full-size electric SUV in its Dynasty family. It measures approximately 5,263 mm long, 1,999 mm wide, and 1,790 mm tall, with a 3,130-mm wheelbase. Its seven-seat cabin uses a 2+2+3 arrangement: two front seats, two separate second-row seats, and a three-person rear row. Official materials promote second-row comfort seating, a large front storage compartment, cabin entertainment options, and family-focused storage.

The China launch introduced four versions. These are Chinese launch prices and CLTC claims, not quotations or certified Australian driving ranges.

Reported launch specifications include approximately 300 kW for the entry rear-wheel-drive version, up to 370 kW for a higher-output single-motor version, and 585 kW total for all-wheel-drive models. BYD quotes 0–100 km/h in as little as 3.9 seconds for the high-performance AWD configuration. These figures vary by trim and should not be interpreted as identical across the lineup.

Can the Great Tang really charge in nine minutes?

BYD promotes a 1,000-volt electrical platform, its second-generation Blade Battery, and what it calls flash charging. The company's China-market claim is charging from 10% to 97% in approximately nine minutes using compatible high-power infrastructure under suitable conditions. The same marketing materials refer to gaining substantial charge in five minutes.

That is a manufacturer claim for a specific charging ecosystem, not a promise that an owner could achieve the same result at an ordinary Australian public DC charger or home AC outlet. Real charging time depends on charger output and compatibility, battery temperature, charge level, system limitations, and local infrastructure. The 950-km headline is a Chinese CLTC test-cycle figure; real-world highway range, cold or hot conditions, speed, passengers, and luggage can all change consumption.

Is the BYD Great Tang available in Australia?

Not as a confirmed local retail model on the BYD Australia vehicle catalog reviewed on November 12, 2026. BYD's Australian site lists battery-electric vehicles such as the ATTO 1 and ATTO 2 city-oriented models, the ATTO 3 family, DOLPHIN hatchback, SEAL sedan, and SEALION 7 SUV. Product availability and upcoming variants should be checked directly with the distributor.

Australians who need more seats can also investigate local plug-in-hybrid options, including the seven-seat SEALION 8. That SUV is not the same as the battery-electric Great Tang. BYD's SEALION 5, SEALION 6, SEAL-series plug-in hybrids, and SHARK 6 ute belong to other categories; a plug-in hybrid uses both a combustion engine and rechargeable battery, while a battery EV does not use an engine for propulsion.

No verified Australian pricing, delivery date, local specification sheet, or Great Tang-specific Australian warranty terms were announced in the checked official local catalog. Chinese yuan prices should not be converted and represented as expected Australian drive-away prices: transport, duties, taxes, equipment, compliance and local distribution can materially change the final figure. Nor should the Chinese rim correction be presented as an Australian recall of unrelated BYD models.

What should Australian EV buyers check after the wheel-rim news?

• Confirm the model and market. Ask the local BYD dealer which exact vehicle and variant is available; do not confuse the Great Tang with existing Tang models in other countries or the locally listed SEALION 8 hybrid.
• Compare the correct range rating. Look for Australian-relevant WLTP figures on locally certified models rather than comparing a Chinese CLTC headline directly with competitors.
• Review wheels and maintenance. For any car with different front and rear wheel widths, understand tire replacement, rotation limitations, spare-wheel arrangements and compatible wheel specifications.
• Check charging realistically. Ask about your home charging setup, suitable charging plugs, routine DC charging speeds and whether the advertised flash-charging hardware is available where you drive.
• Verify safety notices for your actual vehicle. Use the Australian Government's Vehicle Recalls portal and manufacturer or dealer VIN checks rather than assuming an overseas service action applies locally.
• Obtain written terms. Check local battery and vehicle warranty coverage, tire specifications, driver-assistance limitations, servicing access and total on-road costs before ordering.

What happens next for the Great Tang and Australian buyers?

The confirmed near-term action is BYD's announced inspection and rim-correction process for affected owners in China. Whether the company releases a definitive affected-vehicle count or detailed follow-up findings remains unknown. The reported cause and BYD's testing conclusion are company statements; they should be updated if a regulator or another authoritative investigation publishes further evidence.

For Australia, a Great Tang launch remains a possibility rather than a verified plan. If the company announces local homologation, specifications and sales, the important consumer questions will be the local range standard, charging compatibility, right-hand-drive equipment, service support and price—not a speculative conversion of Chinese pricing. Until then, the most useful comparison is with EVs and hybrids actually offered through BYD's Australian network.

Frequently asked questions

Is “reverse rim” a BYD Great Tang technology?

No. It describes the incorrect front-to-rear placement of some staggered-width wheel rims. Rear-wheel steering and crab-walk maneuvering are separate, intentional Great Tang features.

Did BYD recall all Great Tang SUVs over wheel safety?

BYD acknowledged a problem affecting some vehicles and offered free inspections, corrections and warranty resets. It has not published a total affected count in the checked statement. Its own testing found no handling or safety risk; that is the manufacturer's finding, not proof that every concern has been independently resolved.

Can Australians buy the Great Tang now?

No Great Tang retail listing, Australian price or launch date was verified on BYD Australia's official vehicle website as of November 12, 2026. Australian buyers can compare currently listed BYD EVs and plug-in hybrids through its local distributor.
