315/35 R21 Summer Tires – Used

The 315/35 R21 tire size is one of the widest and most powerful summer tire sizes in the premium and performance SUV segment. With a massive 315 mm wide tread and a sporty, low-profile 35 aspect ratio, this size offers extreme lateral stability, maximum braking performance, excellent summer grip, and outstanding high-speed control.

This tire dimension is predominantly used on vehicles that feature:

• very high axle loads,

• large, high-temperature resistant braking systems,

• adaptive sports suspensions,

• powerful internal combustion or electric motors,

• sensitive AWD/Torque-Vectoring systems

.

Therefore, used tires of this size must be inspected particularly strictly, as even minor structural deviations can significantly affect stability, comfort, and safety reserves.

Reifenshop Landshut ensures that every used 315/35 R21 summer tire has an reinforced XL/Extra-Load carcass, documented tread depth, correct LI/SI values, precise concentricity, and a completely OEM-compliant rolling circumference.
