Holden Commodore VT (1997–2000) Tyre Size & Wheel Specs (PCD, CB, Offset, Torque) | Adelaide

The 1997–2000 Holden Commodore VT marked the beginning of the third-generation Commodore platform, introducing improved suspension, larger body dimensions, and better handling compared to earlier models.

This generation remains a popular platform for daily use and performance builds, making it essential to understand correct tyre sizes, wheel specs, PCD, centre bore, and offset.

At Autosport Tyreworld Magill, Wingfield & Clarence Gardens, we regularly service VT Commodores including Executive, Acclaim, S, SS, Berlina and Calais.

Centre Bore (CB) — CORRECT SPEC

• CB: 69.5mm (OEM)

Important notes:

• This applies across VT–VX–VY–VZ platform
• Aftermarket wheels often have larger centre bores (72.6mm / 73.1mm)
• Always use hub-centric rings → 69.5mm
• Ensures proper wheel seating and eliminates vibration

Wheel Offset (ET)

Typical setups:

• 15” → +48
• 16” → +48
• 17” → +40 to +48

Recommended aftermarket range:

• +35 to +45 → Flush fitment
• Lower offset = more aggressive stance

Wheel Nut / Torque Spec

• Recommended Torque: 110 – 120 Nm

Best practice:

• Use a calibrated torque wrench
• Recheck torque after 50–100 km

• Wider wheels may require guard rolling

Common Fitment Mistake (Very Important)

A common issue we see:

Trying to fit VE/VF wheels onto VT

→ VE/VF CB = ~66.9–67.1mm
→ VT CB = 69.5mm

Result:

• Wheel will NOT seat correctly
• Causes vibration or unsafe fitment

Correct solution:

• Use correct bore wheels, or
• Proper machining / hub-centric solution
