275/45 R21 Winter Tires – Used

The 275/45 R21 tire size is one of the large format winter tire sizes predominantly used on premium SUVs, high-performance crossover vehicles, sporty luxury class models, and modern electric SUVs. The wide tread combined with the stable 45-series aspect ratio ensures excellent winter traction, lateral stability, braking performance, and comfort, even with heavy vehicle weights.

Since vehicles in this class often have:

• very high axle loads,

• large braking systems,

• powerful engines or electric motors,

• sensitive all-wheel drive systems (AWD/xDrive/Quattro/4Matic)
  a thorough technical inspection of used winter tires is essential.

Reifenshop Landshut ensures that every used model has sufficient remaining tread depth, functional sipes, an intact carcass, stable roundness, and an OEM-compliant rolling circumference.

This size is also very common on plug-in hybrids and heavy electric vehicles, which require particularly robust winter tires.
