How to Read Mercedes-Benz S-Class Tyre Size?

For example, 255/45 R19 can be understood as follows:

• 255 – tyre width in millimetres.
• 45 – sidewall height expressed as a percentage of tyre width.
• R – radial tyre construction.
• 19 – wheel rim diameter in inches.

S-Class tyres may also carry additional markings such as XL, MO, MOE or manufacturer-specific homologation markings. These specifications can be important when selecting replacement tyres, particularly for a luxury vehicle with performance and comfort requirements.

Which Tyres Are Best for Your Mercedes-Benz S-Class?

The best tyre for an S-Class is not necessarily the most expensive option. Choose a tyre that matches the vehicle's approved specification, your driving conditions and your preferred balance between comfort, performance and durability.

Mercedes-Benz S-Class Tyre Buying Guide

1. Check Your Existing Tyre Size

Check the tyre sidewall and vehicle information label before ordering replacement tyres. S-Class vehicles can use different tyre sizes depending on generation and wheel configuration.

2. Match Load and Speed Rating

Always select replacement tyres that meet the required load and speed specifications for your vehicle.

3. Check Mercedes Original Specification

Mercedes-Benz offers approved tyres developed and tested for its vehicles. Where applicable, check whether your vehicle requires Mercedes Original (MO), MOE or another manufacturer-approved specification.

4. Consider Run-Flat Requirements

Some S-Class applications can use run-flat or extended-mobility technology. Confirm the required tyre construction before purchasing.

5. Consider Your Driving Conditions

If your S-Class is primarily used for city driving, comfort and low road noise may be priorities. For highway and performance driving, stability, wet grip and handling become increasingly important.

6. Get Alignment and Balancing Checked

When replacing tyres, consider checking wheel alignment and balancing to ensure the new tyres perform correctly.
