## Long description

Nankang CR-S 315/30 R21 105Y is a 315/30R21 radial tyre engineered for high-performance on-road use. Designed for fitment on compatible 21-inch wheels, this tyre combines a wide contact patch and a low-profile sidewall to support stability and responsive handling at higher speeds. The load index 105 and speed rating Y indicate the tyre is suitable for heavier passenger vehicles and sustained high-speed driving within the Y-category limit.
Advantages
The tyre offers a broad tread contact area that improves grip on dry roads and contributes to predictable cornering behaviour. Its low-profile construction reduces sidewall flex for more direct steering feedback, while the tread compound and pattern aim to balance traction and wear characteristics appropriate for performance road use. The 315 mm width provides increased surface area for braking and lateral stability.
Suitable for
 High-performance passenger cars with 21-inch wheel fitment
 Drivers seeking responsive handling and stable high-speed behaviour
 Road use on dry and mixed urban/highway surfaces
 Vehicles requiring a tyre with a load capacity corresponding to index 105

How to use
Select the Nankang CR-S 315/30 R21 105Y when your vehicle manufacturer or wheel specifications call for a 315/30R21 tyre and when a performance-oriented, low-profile tyre is required. Have tyres fitted and balanced by a qualified technician, and ensure correct inflation pressure according to the vehicle manufacturer’s placard or handbook. After mounting, perform a wheel alignment check and re-torque wheel fasteners following the installer’s recommendations.
Usage recommendations
Maintain recommended tyre pressures, check tyre condition regularly for uneven wear or damage, and replace tyres when tread depth reaches legal or safety limits. Use tyres of the same size and construction on an axle, and consult vehicle documentation to confirm compatibility with load and speed requirements.
