255/40 R21 Summer Tires – Used

The tire dimension 255/40 R21 is predominantly used in premium SUVs, sporty crossover models, luxury vehicles, and high-performance hybrid/electric platforms.
With a tread width of 255 mm and a flat 40-series aspect ratio, this size offers a combination of sporty directness, precise steering, short braking distances, and high lateral stability, without completely neglecting comfort.

21-inch configurations of this type are often found on vehicles with:

• large brake systems

• high axle loads (SUV/EV)

• all-wheel drive (AWD/xDrive/Quattro/4Matic)

• dynamically designed chassis

Therefore, used summer tires of this dimension must be subjected to particularly strict checks to ensure structural integrity, concentricity precision, and OEM rolling circumference.

Reifenshop Landshut inspects every model according to strict technical criteria – essential for modern performance vehicles.
