Understanding X4 M Tyre Setup

Why This Matters

• Maximises traction under acceleration

• Enhances cornering performance

Important Notes

• No front-to-rear rotation

• Rear tyres wear faster

• Correct sizing is critical for xDrive system

Runflat vs Performance Tyres

Some X4 M vehicles may come with Runflat tyres, but most performance drivers upgrade.

Runflat Tyres

Non-Runflat Upgrade (Recommended)

• Improved ride quality

• Preferred for performance driving
