Mazda BT-50 Tyre Size Australia | Current and Historical Guide

Quick answer

The current Mazda Australia BT-50 brochure lists 255/65R17 tyres on 17×7.0J wheels and 265/60R18 tyres on 18×7.5J wheels. The brochure's tyre index row lists 110S. Because wheel fitment varies by grade, body style and drivetrain, confirm the individual vehicle's tyre placard before ordering.

Earlier Mazda BT-50 generations

Australian BT-50 models from earlier generations used several wheel and tyre packages. Do not apply the current TF-series sizes to an older vehicle solely because the model name is the same. Check the build date, generation, tyre placard and current wheel specifications. This page is the main BT-50 reference; separate tyre-pattern and touring articles remain available for their distinct purposes.

Recommended tyres for the current Mazda BT-50

Size	Continental — primary	Premium alternative	Budget option
255/65R17	Continental 255/65R17	Michelin 255/65R17	Winrun 255/65R17
265/60R18	Continental 265/60R18	Michelin 265/60R18	Simmons 265/60R18

Specific patterns and availability change. Every replacement must meet the placard's complete size, construction, load index and speed rating.

Highway, all-terrain or off-road?

For mainly Adelaide commuting and sealed-road touring, a highway-terrain tyre generally prioritises wet braking, comfort and lower noise. All-terrain tyres can suit gravel roads, worksites and touring but may add noise, weight and rolling resistance. Choose according to real use rather than appearance alone.

Payload, towing and 4WD checks

Confirm the tyre's load capacity is suitable for the placard and intended payload.
Recheck cold pressures when towing or carrying heavy loads, following Mazda's guidance.
On 4WD vehicles, keep all four tyres closely matched in construction, circumference and tread depth.
Check wheel offset, brake clearance and legal rolling diameter before changing wheel size.
Arrange wheel alignment when steering pulls or tyre wear is uneven.
