275/40 R21 Sommerreifen – Gebraucht

The summer dimension 275/40 R21 is a typical size for large premium SUVs, sporty crossover models, modern electric SUVs and powerful all-wheel drive vehicles. The wide 275 mm tread provides a large contact patch for maximum summer grip, while the 40-series profile offers an optimal balance of sportiness, lateral stability, and comfort.

These tires are often found on vehicles with high axle loads, reinforced XL carcasses, large braking systems, adaptive suspensions, and sensitively tuned AWD systems. Therefore, used summer tires of this size must be inspected with particular care.

Reifenshop Landshut ensures that every used 275/40 R21 tire has an intact carcass, documented tread depth, correct LI/SI values, precise run-out accuracy, and an OEM-compliant rolling circumference.
