Isuzu D-MAX Tyre Size Guide Australia
Direct answer
Common Isuzu D-MAX tyre sizes in Australia include 245/70R16, 255/65R17 and 265/60R18. The correct tyre size depends on the D-MAX generation, year, trim level, wheel package and whether the ute is still on factory wheels.
For the current Isuzu D-MAX RG from 2020 onwards, the most common factory-style tyre sizes are 255/65R17 and 265/60R18. Older Isuzu D-MAX models can use different 16, 17 or 18 inch tyre sizes, so always check the tyre placard and current sidewall before ordering.

Why D-MAX tyre choice matters
The Isuzu D-MAX is commonly used for trade work, towing, family duties, gravel roads and regional SA touring. A tyre that works well for city driving may not be the best choice for heavy loads or frequent country trips.
For daily road use, a highway-terrain tyre can be quieter and more comfortable. For towing, job sites, beach driving and gravel-road use, many D-MAX owners prefer all-terrain tyres from brands such as Toyo, Falken, BFGoodrich, Yokohama, Kumho, Pirelli, Hankook, Maxxis and Continental.
Wheel alignment and fitment checks
- Confirm tyre placard size, load index and speed rating.
- Check current tyre sidewall if the vehicle already has aftermarket wheels.
- For all-terrain upgrades, check rim width, wheel offset, suspension height and guard clearance.
- For towing, tools or touring loads, choose a tyre with suitable load rating and construction.
- After fitting new tyres or changing tyre size, check wheel alignment to protect tread life.
