The Dunlop Grandtrek AT5 285/60 R18 is a large all-terrain tyre developed for SUVs and 4x4 vehicles that need a balance between paved-road usability and traction on rougher surfaces. Dunlop Indonesia officially lists this exact size as 285/60 R18 120T XL, with an inflated width of approximately 292 mm, an overall diameter of 807 mm and an 8.5-inch reference rim width. The tyre combines a 285 mm nominal section width, a 60 aspect ratio, radial construction and an 18-inch rim diameter.
The Grandtrek AT5 uses a deep, wide all-terrain tread pattern designed to generate traction on uneven roads and off-road surfaces while retaining stable on-road behaviour. Dunlop developed a dedicated AT5 profile that distributes contact pressure more evenly across the tread, reducing concentrated wear energy and supporting longer tread life. Shoulder-block rigidity is also optimised to control wear in an area that typically experiences higher loading. Stone Ejectors help prevent rocks becoming trapped in the grooves, while the side-block design improves resistance to cuts during rough-surface driving.
Large 285 mm All-Terrain Fitment
At 285 mm wide with a 60 profile, this tyre has a nominal sidewall height of approximately 171 mm. Combined with an 18-inch rim and Dunlop's published 807 mm overall diameter, this creates a very large tyre package that requires sufficient wheel width, suspension clearance and body clearance. It should not be treated as interchangeable with a smaller 18-inch tyre simply because the rim diameter matches.
For Pakistani driving, the AT5 is relevant to SUVs and pickups used across highways, broken roads, gravel tracks and occasional off-road terrain. Dunlop positions it as an all-round tyre that combines on-road stability and comfort with improved wet and off-road performance.
Dunlop Indonesia currently lists this size as 120T XL, while other regional catalogues may use a different speed symbol. Buyers should therefore verify the load index, speed rating and XL marking on the actual tyre before installation. Cold inflation pressure should follow the vehicle manufacturer's recommendation, with regular inspection for cuts, embedded stones and uneven wear.
AT5 Technology
Aggressive all-terrain tread design. The Grandtrek AT5 uses a deep and wide tread pattern designed to improve traction on uneven and off-road surfaces while retaining usable road manners.
AT5-specific tyre profile. Dunlop developed a dedicated profile to distribute contact pressure more evenly across the tread, helping reduce concentrated wear and support longer tyre life.
Optimised shoulder block rigidity. The shoulder area is engineered with increased block stiffness to reduce wear energy in a part of the tyre that is exposed to higher loads during road and off-road use.
Stone Ejectors. Features within the grooves help prevent stones becoming trapped in the tread, reducing stone retention during gravel and rough-road driving.
Cut-resistant side blocks. The outer tread and side-block arrangement is designed to improve resistance to cuts and damage encountered on rough surfaces.
New wear-resistant compound. Dunlop uses a dedicated tread compound designed to improve wear resistance while maintaining wet-road performance.
Improved wet performance. Dunlop states that the AT5 tread and compound were developed to improve wet-road capability compared with the previous Grandtrek AT3.
On-road and off-road balance. The tyre is engineered as an all-round all-terrain pattern, combining rough-surface traction with stability, comfort and durability on paved roads.
XL construction in this size. Dunlop Indonesia officially lists the 285/60 R18 version as an Extra Load specification.
Radial construction. The 285/60 R18 uses radial construction, represented by the R designation in the tyre size.

Understanding Tyre Size 285/60 R18 / How to Read Tyre Size
Vehicles with 285/60 R18 Tyre Size
What does 285/60 R18 mean?
285/60 R18 is the tyre size.
285 is the maximum width of the tyre in milimetres(mm). When the vehicle is fully loaded its width can expand maximum upto 285 milimetres(mm).
60 is the ratio among width and height of the tyre from its rim. it means that the height of the tyre is precisely 60% of the 285mm. Lower ratio improves road grip, but it reduces comfort to some extent.
R – refers to the method the tyre is produced. The letter “R” is found on all modern car tyres. It indicates the radial structure of tyre cosntructed with steel wires.
18 represents the diameter of the rim. It is a measurement in inches(“). This number should be rememberd as it is the measurement of the rims. It has to match exactly to what is mentioned in the car manual.
