315/45 R21 Sommerreifen – Gebraucht

The 315/45 R21 dimension is one of the widest and highest load-bearing summer tire sizes in the premium segment. It is primarily used on large high-performance SUVs, powerful V8/V6 turbo models, sporty AWD vehicles, and heavy electric SUVs.

The large width of 315 mm combined with a 45-series sidewall ensures maximum contact patch, grip, directional stability, traction, and braking force transmission. However, vehicles in this segment have extremely high axle loads, wide braking systems, and precise all-wheel drive distributions, which is why used 21-inch tires must be checked particularly carefully.

Reifenshop Landshut guarantees that every used 315/45 R21 summer tire has an intact high-performance carcass, a documented tread depth, correct load & speed indices, and an OEM-compliant rolling circumference.

3. DOT Analysis & Material Condition

Evaluation of:

• manufacturing year

• temperature-related rubber wear

• potential micro-cracks due to SUV weights

4. Carcass Integrity

Essential for:

• heavy SUVs & sporty models

• maximum braking torque

• stability under cornering loads

Checked are:

• bead areas

• belt packages

• sidewall structure

5. Runout & Vibration Test

Relevance:

• smooth high-speed handling
