The Yokohama GEOLANDAR H/T G056 275/50 R21 is a large highway-terrain tyre developed for midsize and large SUVs that require stable paved-road performance, ride comfort, wet-road capability and long tread life. Yokohama officially lists this exact size as 275/50 R21 113V. The manufacturer's specification gives an overall diameter of approximately 809 mm, an actual tyre width of around 284 mm and an 8.5-inch standard rim width.
The G056 uses a dedicated highway-terrain tread pattern built around four main zigzag grooves. Their shape adds gripping edges while providing major channels for water evacuation and hydroplaning resistance. Multiple lug grooves add further drainage capacity on wet roads, while Adaptive Shoulder Blocks increase shoulder rigidity to support handling and reduce uneven wear. Yokohama also uses three-dimensional sipes that reinforce the tread blocks while maintaining additional edge effect for traction.
Large 21-Inch Highway SUV Fitment
At 275 mm wide with a 50 profile, the tyre has a nominal sidewall height of approximately 137.5 mm. Combined with a 21-inch rim and Yokohama's published 809 mm overall diameter, this creates a substantial SUV tyre package. Yokohama specifies an approved rim-width range of 7.5 to 9.5 inches for this size, with 8.5 inches used as the standard measurement rim.
For Pakistani SUV owners, the G056's highway-terrain focus is relevant to city use, motorway driving and long intercity journeys where stability, comfort, wet-road drainage and tread durability matter more than aggressive off-road traction. Yokohama uses a five-pitch tread arrangement to reduce pattern noise, while its SUV-specific structure is designed to absorb road impacts without sacrificing stability during lane changes and cornering.
Yokohama officially lists the 275/50 R21 G056 as 113V. The tyre should only be fitted where this size and service description meet the vehicle manufacturer's requirements. Wheel width, overall diameter, suspension clearance and load capability must all be suitable. Cold inflation pressure should follow the vehicle manufacturer's recommendation, with regular pressure, alignment and tread inspections used to support even wear and stable highway performance.
G056 Technology
Five-pitch variation. Yokohama uses five different tread-element lengths to disperse noise-frequency peaks and reduce unpleasant pattern noise during road use.
Four Main Zigzag Grooves. Four major longitudinal grooves use a zigzag shape to increase gripping edges while providing water-evacuation channels and strong resistance to hydroplaning.
Multiple Lug Grooves. Optimised lug grooves increase the amount of drainage space across the tread, supporting water evacuation and traction on wet road surfaces.
Adaptive Shoulder Blocks. Thin rib elements within the shoulder design increase block rigidity, support handling performance and help reduce uneven wear and pattern noise.
3D Sipes. Three-dimensional sipes use supporting internal walls to limit tread-block deformation while maintaining useful gripping edges and improving block rigidity.
Multi-Combination Compound. Yokohama blends two polymers with different characteristics to optimise compound behaviour for SUV use across a broad range of operating temperatures.
SUV-specific tyre structure. The G056 uses a dedicated internal structure designed to absorb road impacts while maintaining stability during lane changes and cornering.
Optimised contact-pressure profile. Yokohama develops the tyre profile to distribute contact pressure more evenly and maintain a longer centre contact area, supporting handling, wet performance and tread wear.
Deep tread design. The deep main grooves contribute to the G056's long-wear focus while maintaining water-drainage capacity.
Radial construction. The 275/50 R21 uses radial construction, represented by the R designation in the tyre size.

Understanding Tyre Size 275/50 R21 / How to Read Tyre Size
Vehicles with 275/50 R21 Tyre Size
What does 275/50 R21 mean?
275/50 R21 is the tyre size.
275 is the maximum width of the tyre in milimetres(mm). When the vehicle is fully loaded its width can expand maximum upto 275 milimetres(mm).
50 is the ratio among width and height of the tyre from its rim. it means that the height of the tyre is precisely 50% of the 275mm. 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.
21 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.
