Autosport Tyreworld Expert Tip

For S-Class vehicles like the S350, tyre choice directly affects ride quality more than almost any other factor.

We typically recommend:

• Continental UC7 / PremiumContact C for comfort builds

• Michelin Primacy series for quiet highway driving

• Avoid budget tyres – they significantly reduce ride refinement
