Choosing between several original-equipment all-terrain tyres can be confusing because the names may look similar while their intended applications differ. The Grandtrek AT30 is designed around original-equipment specifications with all-terrain capability, balancing on-road performance with off-road traction. Its availability across different sizes and vehicle applications means buyers should look beyond the pattern name and check the exact specification required for their vehicle.
A Closer Look at the AT25
The Grandtrek AT25 is positioned towards drivers who spend significant time on sealed roads but still require some off-road capability. It is available for selected SUV and 4WD applications, with specifications varying according to the vehicle and tyre size.
For drivers who regularly move between highways, suburban roads, gravel surfaces and occasional unsealed tracks, the AT25 can represent a balanced approach. However, the suitability of a particular version depends on factors such as load index, speed rating, tyre dimensions and the vehicle manufacturer's requirements.
Where the AT23 Fits
The Grandtrek AT23 has a different emphasis, with all-season characteristics and an original-equipment focus. Its tread design is intended to provide dependable road contact across changing conditions, making the specification relevant to drivers who encounter wet roads and varying weather throughout the year.
The AT23 should still be considered according to its exact size and rating rather than simply comparing it with another Grandtrek pattern by name. Different vehicle applications can have different requirements, even when the tyre family is similar.
Understanding the AT22
The Grandtrek AT22 is another all-terrain option intended for mixed on- and off-road driving. It has been used across various SUV and 4WD applications and is suited to drivers who want a tyre capable of handling everyday sealed roads while also accommodating occasional or regular travel on unsealed surfaces.
Its relevance will depend heavily on the vehicle and the particular size being considered. Checking the complete tyre specification is therefore essential before making a replacement decision.
So, What Actually Separates Them?
Rather than treating the four patterns as interchangeable, consider their intended vehicle application and driving environment.
• AT30: OE all-terrain design focused on balancing everyday road use with off-road capability.
• AT25: Suited to mixed driving where highway use remains an important part of the vehicle's operation.
• AT23: Emphasises all-season road characteristics and traction across changing conditions.
• AT22: Designed for mixed-surface driving, combining everyday road use with off-road capability.
Why OE Fitment Matters
The model name alone does not determine whether a tyre is suitable for a particular vehicle. Size, load index, speed rating, wheel compatibility and the vehicle manufacturer's requirements all need to align.
This is particularly important for 4WDs and SUVs, where the vehicle may be used for towing, carrying passengers and travelling across different road surfaces. A tyre that fits the wheel physically may not necessarily meet the required specification for the vehicle.
