Michelin 275/45 R21 107Y Latitude Sport 3 MO 2025

About Michelin Latitude Sport 3 275/45 R21 107Y MO

The Michelin Tyres Latitude Sport 3 is positioned as a high-performance SUV summer tyre rather than a general-purpose all-terrain product. The MO marking identifies the Mercedes-Benz homologated version. For a suitable vehicle, this matters because the tyre has been developed around an original-equipment application rather than simply matching the physical dimensions of the wheel.

How the 275/45 R21 Profile Feels on the Road

The 275 mm section width gives the Latitude Sport 3 a substantial footprint, while the 45 profile provides less sidewall movement than a taller SUV tyre. That combination should favour direct steering and stable behaviour when changing direction at highway speeds. The trade-off is that a 21-inch wheel with a 45-series sidewall cannot be expected to absorb sharp potholes as softly as a taller-profile configuration. Drivers who value controlled handling over maximum cushioning are more likely to appreciate this setup.

Tread Design for Dry Roads and Heavy Rain

Michelin uses a broad road-oriented tread with longitudinal drainage channels and substantial shoulder areas. The manufacturer states that the Latitude Sport 3 has a larger tread contact footprint than its predecessor and increased groove area to improve water evacuation. For this exact 275/45 R21 version, the European product information gives an A wet-grip classification and C fuel-efficiency class. The tread is therefore particularly relevant to drivers who regularly encounter wet motorway surfaces rather than loose gravel or serious off-road conditions.

Where the MO Specification Matters

The MO suffix is one of the important details in this particular product. It denotes Mercedes-Benz homologation, so the tyre is especially relevant when replacing an original-equipment set on a compatible Mercedes-Benz vehicle. The 107 load index should also be checked against the vehicle's door-placard or manufacturer specification rather than assumed suitable simply because the dimensions match. Michelin lists this size as a sport-oriented SUV application, making vehicle approval and axle requirements important before purchase.

Comfort, Noise and Everyday Driving

This configuration balances performance with road usability, but it should not be confused with a comfort-first touring tyre. The relatively low 45-series sidewall can transmit more impact from broken surfaces than a higher-profile SUV tyre. The standard MO version is also different from the MO-S Acoustic version, which uses additional noise-reduction technology. For buyers sensitive to cabin noise, comparing the exact marking is therefore more useful than comparing the Latitude Sport 3 name alone.

Who This Tyre Makes Sense For

The Michelin Latitude Sport 3 275/45 R21 107Y MO is most appropriate for drivers of compatible premium SUVs who spend the majority of their time on paved roads and want confident dry and wet-road behaviour with a responsive steering character. It is not the obvious choice for regular off-road driving, severe winter conditions or buyers whose first priority is maximum ride softness. Compared with the Michelin Pilot Sport 4 SUV in 275/45 R21, the Latitude Sport 3 is the more established road-focused Latitude option, while the Pilot Sport 4 SUV uses a different 110Y XL configuration, so the two should not be treated as interchangeable purely because the dimensions are similar.

For Dwbtyres customers looking to buy car tyres in UAE, the 2025 Michelin Latitude Sport 3 275/45 R21 107Y MO offers a strong combination of SUV road stability, wet grip and high-speed capability. The important checks before ordering are the vehicle's approved size, the 107 load index, Y speed rating and whether the Mercedes-Benz MO specification matches the vehicle's original tyre requirement.
