BYD Shark 6 wheels: what sizes and offsets fit?

The documented BYD Shark 6 wheel examples below use 6x139.7, with 18x9 sizes and +25 mm offsets in the stated applications. These are wheel-maker examples, not a claim that the largest listed rim is the physical or legal maximum.

Australian Shark 6. The factory package is the May 2026 specification covering Dynamic Cab Chassis, Premium and Performance. Aftermarket wheel examples are ROH's Shark 6 application, not a general BYD or hybrid-ute approval.

What is the largest wheel size worth fitting?

The documented Shark 6 wheel example here uses 18 inches. That matters: a matching six-stud pattern does not establish that a 17-inch wheel clears the brakes or suits the exact vehicle. Get the application in writing before downsizing.

A larger metal wheel does not necessarily mean a taller tyre. For touring, our preference is the smallest wheel with a confirmed brake application that supports the chosen tyre and load. For a road-focused look, a larger wheel can be considered while keeping a suitable outside tyre diameter. That is a style and use-case choice, not proof that an unlisted rim fits.

What factory wheel and tyre sizes are documented?

These are scoped examples, not a size chart for every year or variant. Match the tyre placard and wheel markings on your own vehicle. Read the original reference.

Choose tyre diameter and wheel diameter separately

The wheel is the metal rim inside the tyre. A larger wheel does not necessarily make the complete assembly taller: tyre sidewall can decrease to keep a similar outside diameter.

For the 265/65R18 reference, nominal outside diameter is 801.7 mm and sidewall height is 172.2 mm on each side. If the same outside diameter were maintained on a 17-inch wheel, each sidewall would be 12.7 mm taller. This is geometry, not proof that a matching tyre product or brake-clearing wheel exists.

For touring we would compare sufficient sidewall with the look you prefer, rather than choosing the largest visible wheel. Keep the wheel barrel, caliper clearance and the tyre's approved rim width in that comparison.

What stud pattern, wheel width and offset fit?

Selected vehicle application

ROH's current table lists the following examples as recommended for that selector.

A wheel manufacturer's application and load rating do not approve every tyre fitted to that wheel. The exact part number, attachment hardware, brakes, tyre, vehicle load and modifications still need to agree. These examples explain specification choices; they are not a ranking of wheel brands.

How far will a different offset move the wheels?

Offset is the distance between the wheel centreline and its mounting face. With width unchanged, reducing a positive offset, or making a negative offset more negative, moves the wheel outwards.

The offset values below illustrate the change between two same-width wheels. They correspond to the selected ROH example and a lower-offset option where documented; the diagram itself is not a fitment approval.

Moving from ET +25 to ET +12 at the same nine-inch width moves each wheel 13 mm outwards. A matching pair increases track by 26 mm, assuming the original hubs and axle geometry stay the same. This says where the wheel moves, not whether the tyre stays covered or clears the vehicle.

Why wheel width matters too

A change from an eight-inch rim to a nine-inch rim adds 25.4 mm of nominal width. At the same offset, that places each nominal rim edge 12.7 mm further from the centreline: one edge moves out and the other moves in. The tyre section itself is not the rim width.

If width and offset both change, compare both dimensions. The outward rim-edge change is half the width change in millimetres, plus the old offset minus the new offset. Actual tyre bulge and rim-lip shape require the product data and a physical check.

Should you choose the biggest rim or more sidewall?

BYD's May 2026 specification describes double-wishbone suspension front and rear. Treat the Shark as its own vehicle, rather than using a leaf-sprung diesel ute's wheel and lift package as evidence. Include the exact variant and axle limits in the quote.

For a daily or restrained tourer, our first visual comparison would use a wheel that keeps the tyre within a technically suitable package. Then compare dark, bronze and machined finishes against the actual vehicle colour. The best-looking choice is personal; a negative number is not automatically a better stance.

What wheel offset is legal in Queensland or Victoria?

There is no single legal offset number for every BYD Shark 6. Work from the manufacturer's maximum wheel track for the particular model and assess the front and rear axles separately. A wheel manufacturer's ‘recommended’ label does not replace that calculation.

For eligible off-road and goods vehicles, Queensland's current minor-modification guidance and VSB 14 Section LS clause 4.2.11 used in Victoria set a 50 mm maximum track increase over the manufacturer's maximum. Passenger-car rules differ. With unchanged hubs, moving each same-width wheel 25 mm out increases track by 50 mm. That is an illustration, not permission to subtract 25 from any wheel already fitted.

Tyres must remain covered and clear the vehicle through steering and suspension movement. Wheel load, tyre-to-rim approval, brake clearance, speedometer accuracy and any existing approval conditions still apply. Flares address coverage; they do not increase the permitted track or tyre-diameter allowance.

Read the Queensland tyre, lift and wheel rules or Victoria's tyre, lift and wheel rules for the conditions and approval routes. Melbourne follows the Victorian rules. These are not a national legal offset chart.

Before placing the order

• Confirm generation, grade, build date and any existing brake, axle or suspension changes.
• Obtain the exact wheel part number, stud pattern, attachment hardware and brake-clearance application.
• Match tyre model and size to the wheel's approved width and the vehicle's required load and speed specifications.
• Check tyre coverage, full-travel clearance, spare-wheel compatibility and the state requirements for your complete wheel, tyre and lift package.

Questions about BYD Shark 6 wheels

Can I keep the factory Shark 6 wheel with a wider tyre?

Only if the exact tyre version approves the eight-inch rim and meets the vehicle’s load, speed and clearance requirements. The same nominal size can have different LT and passenger constructions and published dimensions.

Does the stud pattern alone prove a wheel fits?

No. Confirm centre bore, wheel-nut seat and thread, brake clearance, load rating, width and offset for the exact part number. The matching spare also needs a practical mounting and clearance check.

Can I use a wider wheel with my existing tyre?

Only within that exact tyre version's approved rim range. A nine-inch wheel appearing in a vehicle application does not make every factory tyre suitable for it. Read the manufacturer row, including LT, passenger or XL construction, before combining the parts.

Compare wheels on your own BYD Shark 6

Use your own photo to compare the designs and finishes available in Nordak. Keep the whole build in view, including the bar, tray, canopy and paint. See wheels on your vehicle, then take the preferred look and exact specification to your supplier.
