BYD DOLPHIN

This independent guide covers the suspension layout, wheel specifications, and tyre management for the BYD DOLPHIN in Australia. The BYD DOLPHIN is a front-wheel drive pure electric (BEV) hatchback; all information on this page relates exclusively to that powertrain. Please note that trim names, specifications and prices reflect a compiled dataset (October 2026) and that BYD Automotive Australia may update variants, so every figure must be confirmed with an authorised BYD dealer or the official BYD Australia website.

Suspension Layout and Variant Differences

The BYD DOLPHIN features different suspension configurations depending on the variant chosen. At the front, all specifications use a MacPherson strut design. At the rear, the configuration changes between trims: the Essential variant uses a rear torsion beam, while the Premium variant is fitted with a multi-link rear suspension. Owners evaluating the BYD DOLPHIN rear torsion beam versus the multi-link setup for ride comfort should note that these are the factory-defined designs for each trim — refer to the official owner’s manual and consult an authorised BYD dealer for detailed ride characteristic information.

Key chassis dimensions relevant to the suspension setup are listed below:

Any inspection of underbody components or suspension work should be carried out by an authorised BYD dealer or qualified technician. Do not attempt to service or modify suspension components without professional guidance, as this may affect vehicle safety and warranty coverage.

Wheels, Tyres, and Factory Sizes

The BYD DOLPHIN is fitted with factory alloy wheels, with the tyre size varying by trim. The Essential variant uses 195/60 R16 tyres, while the Premium variant uses 205/50 R17 tyres. Owners researching BYD DOLPHIN tyre sizes — 195/60 R16 for the Essential and 205/50 R17 for the Premium — should verify fitment against the placard located on the vehicle, as this is the authoritative source for load rating and pressure specifications.

When considering tyre replacement or an upgrade — for example, moving from the factory-fitted tyres to an alternative brand — confirm the load rating, speed symbol, and overall diameter are consistent with factory requirements. Consult an authorised BYD dealer before selecting any tyre outside the factory specification to ensure compatibility with the vehicle’s safety systems.

EV Weight, Torque, and Tyre Wear

The BYD DOLPHIN is a front-wheel drive vehicle with a permanent magnet synchronous motor. The Essential produces a maximum torque of 180 Nm, and the Premium produces a maximum torque of 310 Nm, both delivered through the front wheels. Because torque is delivered to the front axle, front tyre condition and wear should be monitored as part of routine maintenance.

The kerb weight of the BYD DOLPHIN — 1,506 kg for the Essential and 1,658 kg for the Premium — reflects the inclusion of the BYD Blade Battery (44.9 kWh and 60.48 kWh respectively). This vehicle weight is a relevant factor when selecting replacement tyres with an appropriate load rating. If owners observe uneven tyre wear, refer to the official owner’s manual for tyre rotation intervals and correct inflation pressures, and have the suspension geometry checked by an authorised BYD dealer.

Alignment and Steering Feedback

Correct wheel alignment ensures even tyre wear and proper vehicle tracking. Under the BYD warranty, wheel alignment and balancing are listed as items for which a charge may be made; they are not covered for standard wear under the new vehicle warranty. Alignment should be checked if the vehicle pulls to one side, after an impact with a kerb or pothole, or if abnormal tyre wear is observed.

The BYD DOLPHIN is equipped with lane departure assist, emergency lane keeping assist, and lane keeping support as standard safety features. If owners notice an unexpected sensation through the steering wheel and wish to determine whether it originates from a driver assistance system or from a mechanical cause such as wheel imbalance, this should be diagnosed by an authorised BYD dealer or qualified technician. Any calibration of steering angle sensors or ADAS components is specialised work; confirm with BYD Automotive Australia that the correct procedure is followed before any intervention.

Bushings, Noises, and Suspension Maintenance

The suspension system — MacPherson strut at the front, torsion beam or multi-link at the rear depending on variant — contains rubber bushings, joints, and dampeners that absorb road imperfections. These components are subject to wear over the vehicle’s life and may produce noises or changes in ride quality as they age.

Because the BYD DOLPHIN operates without an internal combustion engine, the cabin is notably quieter than a petrol vehicle. This means suspension noises, such as knocking or creaking over rough surfaces encountered on Australian roads, can be more perceptible to occupants. If such sounds are noticed, have the suspension assembly inspected by an authorised BYD dealer rather than attempting your own investigation of underbody components. Any replacement of suspension parts must use specifications subject to manufacturer specifications; confirm with BYD Automotive Australia that the correct components are used to protect warranty coverage.

Tyre Pressure Monitoring and Management

The BYD DOLPHIN is equipped with a tyre pressure monitoring system (TPMS) as standard safety equipment. This system alerts the driver when pressure in any tyre drops below the manufacturer’s specified threshold. Correct tyre inflation is important for maintaining vehicle stability and the efficiency that supports the BYD DOLPHIN’s WLTP range of 340 km (Essential) or 427 km (Premium).

Correct cold inflation pressures are found in the official owner’s manual and on the tyre placard fitted to the vehicle. Refer to the official owner’s manual for the precise pressures applicable to your variant and load conditions. If the TPMS warning light activates, check all four tyres with a calibrated cold gauge and adjust pressures accordingly. If the warning light remains illuminated after pressures have been corrected, the sensors must be inspected by an authorised BYD dealer. Do not rely solely on visual inspection to confirm inflation — use an accurate gauge.

Tyre Replacement Guidance

Tyres are not covered by the BYD vehicle warranty; they are subject to the individual tyre manufacturers’ warranties. When replacing tyres, match the factory-specified size for the variant — 195/60 R16 for the Essential or 205/50 R17 for the Premium — and ensure the load index and speed rating meet or exceed the factory requirements listed in the official owner’s manual.

Wheel alignment and balancing are recommended whenever new tyres are fitted and are chargeable items under the BYD service schedule. These are not warranty-covered wear items. If owners are uncertain about which tyre brands or specifications are appropriate, consult an authorised BYD dealer for guidance on fitment that is compatible with the vehicle’s kerb weight and safety systems.
