BYD SEAL

This page provides an independent reference guide covering the suspension layout, wheel specifications, and tyre management for the BYD SEAL in Australia. 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.

As a pure electric (BEV) sedan, the BYD SEAL carries a substantial kerb weight of 2,055 kg (Premium) or 2,185 kg (Performance) and delivers instant torque to the wheels. These characteristics directly influence tyre wear rates and suspension behaviour. This document outlines the factory specifications without providing step-by-step repair instructions, as all mechanical and high-voltage work must be performed by an authorised BYD dealer or qualified technician. Furthermore, any diagnostic assessment of the suspension, alignment, or high-voltage components should never be attempted at home. High-voltage orange cables must not be touched or opened by owners under any circumstances.

Suspension Layout and Adaptive Damping

The BYD SEAL chassis features a double wishbone front suspension, which influences handling dynamics alongside the multi-link rear suspension. This configuration is standard across both the Premium and Performance variants, providing the mechanical foundation for the vehicle’s dynamic characteristics. The wheel track measures 1,620 mm at the front and 1,625 mm at the rear, resting on a wheelbase of 2,920 mm.

Damping technology differs depending on the variant. The Premium variant is equipped with Frequency Selective Damping shock absorbers, which adjust to road inputs mechanically. The Performance variant upgrades to the DiSus-C adaptive damping system, along with Intelligent Torque Adaptation Control (iTAC) to manage the combined 670 Nm of maximum torque from its dual electric motors. Owners seeking details on the operational parameters of these systems should refer to the official owner’s manual. Any inspection of the shock absorbers, bushings, or linkages must be done by an authorised BYD dealer.

Ground Clearance and Driveway Navigation

Navigating steep driveways and obstacles requires awareness of the vehicle’s ride height. The unladen ground clearance is 149 mm for the Premium variant and 145 mm for the Performance variant. These figures decrease when the vehicle is loaded towards its gross vehicle mass of 2,501 kg or 2,631 kg respectively.

Drivers should approach aggressive ramps and speed bumps with caution to protect the undercarriage, which houses the BYD Blade Battery. The underbody components, including the high-voltage systems and battery casing, are critical. For any concerns regarding underbody impacts or clearance limits, consult an authorised BYD dealer for a professional assessment.

Wheel and Tyre Specifications

Both variants of the BYD SEAL are fitted with alloy wheels and 235/45 R19 tyres from the factory. Maintaining the correct tyre pressure is vital for vehicle safety, range efficiency, and even tread wear. Owners must check tyre pressures regularly when the tyres are cold.

When assessing tyre wear or considering a replacement for the 235/45 R19 tyres, replacements must meet the vehicle’s load and speed rating requirements. Using incorrect tyre specifications can compromise the handling and safety systems. For exact replacement recommendations and to ensure compatibility with the vehicle’s mass, always confirm with BYD Automotive Australia or a certified tyre professional.

Electric Vehicle Tyre Wear Characteristics

The pure electric powertrain of the BYD SEAL delivers maximum torque instantly—up to 360 Nm in the Premium and 670 Nm in the Performance variant. Combined with the substantial kerb weight, this places immense rotational and lateral forces on the tyres during acceleration, braking, and cornering.

Consequently, tyres on electric vehicles can exhibit different wear patterns compared to those on lighter internal combustion vehicles. The absence of engine noise also means that tyre roar or changes in tread patterns become more noticeable in the cabin. Owners should monitor tread depth across the entire width of the tyre. Uneven wear across the tread blocks may indicate alignment issues or incorrect inflation pressures. Rotating the tyres at appropriate intervals can help distribute wear evenly. For proper rotation patterns and intervals, refer to the official owner’s manual or have the procedure carried out by a qualified technician.

Wheel Alignment Specifications

Maintaining correct suspension geometry is essential for safe handling and optimal tyre life. Over time, impacts from potholes or kerb strikes can alter the factory alignment. If the vehicle pulls to one side, the steering wheel is off-centre, or the tyres show uneven wear, a four wheel alignment to adjust camber, caster, and toe specs may be required.

Adjusting the wheel alignment involves specialized equipment and knowledge of the factory geometry. Because the vehicle features advanced driver assistance systems (ADAS) that rely on precise steering angles, recalibration of these systems may be necessary following alignment adjustments. Therefore, wheel alignment and any associated ADAS calibration are subject to manufacturer specifications and must be performed by an authorised BYD dealer or suitably equipped specialist.

Warranty Coverage Exclusions

The BYD SEAL is covered by a New Vehicle Warranty of 6 years or 150,000 km, starting from the date of first registration (in Western Australia, this commences from the date of delivery). However, specific suspension and wheel-related components are treated as wear-and-tear items.

According to the official warranty documentation, tyres are not covered by the BYD warranty; they are subject to the tyre manufacturers’ warranties. Furthermore, wheel alignment and balancing, tyres, and gas struts are items for which a charge may be made. Damage resulting from loading the vehicle beyond its gross vehicle mass specifications (2,501 kg for Premium or 2,631 kg for Performance), racing, or unauthorised modifications is strictly not covered. Failure to service the vehicle strictly per the manufacturer’s recommendations or the use of non-recommended parts causing damage will also void coverage. Any queries regarding warranty applicability should be directed to an authorised BYD Service Centre.

Frequently Asked Questions

Does the BYD SEAL have Frequency Selective Damping shock absorbers?

Yes, the Premium variant features Frequency Selective Damping, while the Performance variant uses the DiSus-C adaptive damping system.

What size are the wheels and tyres on the BYD SEAL?

Both the Premium and Performance variants are equipped with alloy wheels and 235/45 R19 tyres.

What is the ground clearance for steep driveways?

The unladen ground clearance is 149 mm for the Premium variant and 145 mm for the Performance variant.

Are tyres and wheel alignments covered by the BYD warranty?

No, tyres are not covered by the BYD warranty, and wheel alignment and balancing are considered wear-and-tear items for which a charge may be made.

Where can I get the camber, caster, and toe specifications adjusted?

Because alignment may affect safety systems and requires specific data, it is subject to manufacturer specifications and should be performed by an authorised BYD dealer or qualified technician.
