GWM Tank 300 Tyre Size: Quick Answer

For current Australian-market GWM Tank 300 variants, the factory tyre size depends on the grade: 265/65R17, 265/60R18 or 265/65R18. The vehicle tyre placard is the final authority because specifications can change by model year, powertrain and wheel package.

Australian variant	Factory tyre size	Factory wheel
Lux Diesel	265/65R17	17-inch black alloy
Ultra Petrol	265/60R18	18-inch black alloy
Ultra Diesel	265/60R18	18-inch chrome alloy
Ultra Hybrid	265/60R18	18-inch chrome alloy
Lux PHEV	265/65R18	18-inch two-tone alloy
Ultra PHEV	265/65R18	18-inch two-tone alloy

Replacement or upgraded tyres should not be selected from diameter alone. Wheel width and offset, brake and suspension clearance, legal requirements and intended load or off-road use also need to be checked on the individual vehicle.

How to Confirm the Correct Tank 300 Tyre Size

Start with the tyre placard on the individual vehicle, then compare it with the size and service description moulded into the current tyre sidewall. The placard is more reliable than selecting by model name alone because a Tank 300 can have a different powertrain, grade or factory wheel package.

Read the full size, such as 265/65R17, 265/60R18 or 265/65R18.
Record the load index and speed rating, not only the width and rim diameter.
Confirm whether the wheels are factory equipment or an aftermarket fitment.
Check that the spare tyre remains suitable for the planned setup.

Why Tank 300 Tyre Sizes Differ by Variant

The current Australian range uses both 17-inch and 18-inch wheels. The wheel diameter and tyre sidewall profile vary by grade, so two Tank 300 vehicles may legitimately show different factory tyre sizes. This is why a generic search result should be treated as a starting point, not the final fitment instruction.

Can You Fit a Different Size?

A different tyre or wheel package may be possible, but it needs a vehicle-specific check. Overall diameter, wheel width, offset, brake clearance, suspension clearance, load and speed ratings, steering clearance, spare-tyre compatibility and applicable South Australian requirements all matter. Changes can also affect speedometer accuracy and vehicle systems if the rolling diameter moves outside an appropriate range.

Before ordering, ask for a professional fitment check and do not assume that a size used on another Tank 300 will automatically suit yours.

Choosing a Tyre for Adelaide and South Australian Driving

The right pattern depends on how the vehicle is used. A Tank 300 driven mainly on sealed Adelaide roads may prioritise wet braking, comfort and road noise. Regular gravel, touring or off-road use may call for a different balance of tread design and construction. Towing, accessories and operating load should also be discussed before selecting the load rating and pressure setup.

Whatever the use case, correct fitting, balancing, tyre pressures and wheel alignment help the new setup operate as intended.

Tank 300 Tyre Size FAQs

What is the factory tyre size for a GWM Tank 300 in Australia?

The current GWM Australia brochure lists 265/65R17, 265/60R18 and 265/65R18, depending on the variant. Confirm the tyre placard on the individual vehicle.

Does every Tank 300 use the same tyre size?

No. The size varies by grade, powertrain and factory wheel package, and specifications can change across model years.

Can I use an 18-inch setup if my Tank 300 has 17-inch wheels?

A change may be possible, but the complete wheel and tyre package must be checked for overall diameter, wheel width and offset, load and speed ratings, clearances, spare compatibility and applicable requirements.

Should I get a wheel alignment after fitting new tyres?

An alignment check is sensible when fitting new tyres, changing the wheel setup, or when the vehicle shows uneven wear, pulling or an off-centre steering wheel.
