For the Porsche Cayenne (958 / E2 generation, 2010–2017), the 21-inch Turbo II wheel is a hallmark of the Turbo and Turbo S models. Finding a set with DOT22 (manufactured in 2022) and 6–7mm of tread is an excellent find for 2026, as it represents a “mid-life” set with modern rubber on classic forged rims.

1. Technical Specifications

Unlike the Macan, the Cayenne 958 typically uses a square setup (the same size on all four corners) for the 21-inch Turbo II design.

• Rim Size: $10\text{J}\times 21$ ET50

• Part Number: 958.362.142.02 (standard Titanium finish) or 7P5.601.025.M.

• Bolt Pattern: $5\times 130$ (Note: This is different from the Macan’s $5\times 112$).

• Tire Size: $295/35\text{ R21}$ (Standard Porsche N-Spec).

• Construction: These are high-quality forged wheels (often manufactured by BBS or Alcoa for Porsche), making them significantly stronger than cast replicas.

2. Condition Analysis (DOT22 & 6-7mm)

• Tire Age (DOT22): In February 2026, these tires are roughly 4 years old. Porsche generally recommends replacing tires every 6 years regardless of tread, so you have approximately 2 solid seasons of safe use remaining before the rubber compound begins to harden significantly.

• Tread Depth (6-7mm): New summer tires typically start with 8mm.

  • 7mm: ~85% life remaining.

  • 6mm: ~70% life remaining.

  • This depth is ideal; the tires are “broken in” but still offer excellent hydroplaning resistance.
