Dunlop 265/70 R18 116H Grandtrek AT23 T0 2025

The Dunlop Grandtrek AT23 T0 265/70 R18 116H is a large SUV all-season tyre designed around stable road manners, useful wet-weather traction and the demands of heavier four-wheel-drive vehicles. Its 265 mm width and tall 70-series profile create a substantial contact patch while retaining enough sidewall to absorb broken road surfaces more effectively than a low-profile 18-inch performance tyre. The 116 load index permits up to 1,250 kg per tyre, while the H speed rating allows speeds up to 210 km/h. The T0 marking identifies an OE-specific Toyota application, so this configuration should be selected according to the vehicle manufacturer's approved specification rather than size alone. 0

About Dunlop Grandtrek AT23 T0 265/70 R18 116H

The Grandtrek AT23 is positioned as an all-season highway-oriented SUV tyre with enough versatility for mixed road conditions. It is not designed around aggressive mud-terrain driving. Instead, its tread layout gives priority to predictable contact on asphalt, water evacuation and reduced pattern noise, while the substantial 70-series sidewall makes it suitable for larger SUVs that may encounter rougher roads. Dunlop Tyres buyers should pay particular attention to the T0 marking because OE versions can have vehicle-specific construction or tuning even when the basic size and service description appear identical.

The 265/70 R18 profile and SUV stability

The tall sidewall is one of the most noticeable characteristics of this configuration. Compared with a 265/50 R20 or similar low-profile SUV tyre, the 70-series profile gives the AT23 more sidewall movement over potholes, road joints and uneven surfaces. Steering response is consequently controlled rather than sharply sporty. The 265 mm footprint helps compensate by giving the vehicle a broad contact area, which is useful during highway cruising, lane changes and braking with a heavily loaded SUV.

Five-pitch tread with four main water channels

The AT23 uses an M+S-rated all-season tread with four circumferential grooves running through the tread. These channels provide clear routes for water to leave the contact patch, while the surrounding tread blocks maintain road contact as the tyre rotates. Dunlop's five-pitch technology varies the sequence of tread elements to reduce repetitive pattern noise, an important consideration for a large SUV that may spend many hours on highways. The pattern is substantially more road-oriented than a mud-terrain tread, which explains its relatively composed pavement behaviour. 1

Highway comfort and road noise

The AT23's design makes it better suited to everyday highway use than its all-terrain appearance might suggest. The relatively continuous central tread areas help maintain straight-line stability, while the five-pitch arrangement is intended to reduce the droning sound often associated with repeated tread blocks. The documented 265/70 R18 version has an external rolling-noise figure of 72 dB in current tyre listings. It is still a large SUV tyre, so suspension condition, vehicle weight and road surface can have a greater effect on cabin noise than the tread pattern alone. 2

Wet roads and changing seasonal conditions

The four circumferential grooves are central to the AT23's wet-weather behaviour, helping move water away from the footprint. Dunlop's published product information specifically identifies the grooves as contributing to wet traction and its advanced tread as supporting wet-weather performance. The 265/70 R18 specification carries a UTQG traction grade of A and a temperature grade of A. It is an all-season tyre, but the documented version is not Severe Snow Service rated, so drivers facing regular heavy snow or ice should use a tyre designed specifically for those conditions. 3

Load capacity and demanding SUV use

With a 116 load index, this configuration is rated for 1,250 kg per tyre, giving a total theoretical tyre load capacity of 5,000 kg across four tyres when considered independently of the vehicle's actual axle and chassis limits. The tyre itself should never be used to exceed the vehicle manufacturer's permitted axle or gross vehicle weight. The 7 to 9-inch approved rim-width range also gives useful fitment flexibility, although the vehicle manufacturer's specified wheel width remains the deciding factor. The tyre is listed as standard load rather than XL despite its high load index. 4

Who this AT23 specification suits

The Dunlop Grandtrek AT23 T0 265/70 R18 116H is most appropriate for large SUV owners who want a comfortable, stable all-season tyre for predominantly paved driving, with additional versatility for gravel roads and less-developed surfaces. It is less suitable for drivers seeking aggressive mud traction, specialist rock-crawling ability or the immediate steering response of a low-profile performance tyre. For buyers planning to buy car tyres in UAE, its warm-weather road capability, high load index and substantial sidewall make it a practical choice for large SUVs, but exact OE approval remains important.

Comparison with a more aggressive all-terrain tyre

Compared with a more aggressive all-terrain design, the AT23 sacrifices some loose-surface bite in exchange for smoother highway behaviour, lower pattern noise and more predictable pavement handling. The published 360 A A UTQG rating means a treadwear grade of 360, traction grade A and temperature grade A. This should not be converted into a guaranteed mileage figure because actual tread life depends on alignment, inflation, vehicle weight, driving habits and road conditions. Current product listings identify Japan as the country of origin for the 265/70 R18 116H version and list 2025 production for this supplied configuration. For Dwbtyres customers, the T0 marking and sidewall specification should be checked before fitting. 5
