Pirelli 245/40 R17 91W Cinturato P7 MO 2024

The Pirelli Cinturato P7 MO 245/40 R17 91W is a summer touring tyre developed for passenger cars and carrying Mercedes-Benz Original Equipment approval. This exact configuration combines a 245 mm section width, 40-series profile and 17-inch rim with a 91 load index and W speed rating. The load index permits up to 615 kg per tyre, while the W rating corresponds to a maximum speed of 270 km/h. The MO marking identifies this version as a Mercedes-approved fitment.

About Pirelli Cinturato P7 MO 245/40 R17 91W

The Pirelli Cinturato P7 MO 245/40 R17 91W is a road-focused summer tyre intended to balance handling, wet-road performance, comfort and rolling resistance. Pirelli lists this exact specification with D fuel-efficiency classification, B wet-grip classification and B external rolling-noise classification at 71 dB. The MO approval is significant for compatible Mercedes-Benz applications because it identifies the tyre as an original-equipment specification rather than simply a standard Cinturato P7 in the same size. For Dwbtyres customers looking to buy car tyres in UAE, matching the complete 245/40 R17 91W MO specification is important when replacing an OE tyre.

Dry-road handling and steering response

The 245 mm tread width combined with a 40-series sidewall gives this configuration a more responsive road character than a taller-profile touring tyre. Pirelli describes compact central tread blocks and a robust external area as supporting steering response and cornering control. This makes the Cinturato P7 suitable for drivers who want controlled directional changes and stable cornering while retaining the road manners expected from a touring tyre. It remains a road tyre rather than a track-focused performance product.

Wet-road grip and aquaplaning control

The exact 245/40 R17 91W MO specification carries a B wet-grip classification. Four wide longitudinal grooves are incorporated into the tread to help evacuate water and maintain control when there is a risk of aquaplaning. Pirelli also positions the Cinturato P7 around braking and handling performance on wet roads. Actual grip will depend on tyre condition, tread depth, inflation pressure, road surface and temperature, so the label rating should not be interpreted as a guarantee of identical braking distances in every situation.

Tread pattern and ride comfort

The Cinturato P7 uses an optimised tread pattern with a specific pitch sequence, compact central blocks, a robust shoulder area and four broad longitudinal grooves. Pirelli states that the pitch arrangement contributes to a relaxed and comfortable acoustic driving experience. The tread design is therefore aimed at consistent paved-road use rather than snow, severe winter conditions or off-road driving. The 40-series sidewall provides sharper response, although drivers moving from a higher-profile tyre may perceive a firmer road feel.

Efficiency, noise and everyday use

Pirelli lists D fuel efficiency for this exact MO configuration, alongside B external rolling noise at 71 dB. These figures indicate a balanced touring design rather than a tyre developed solely for minimising rolling resistance. The advanced hybrid material described by Pirelli is intended to support more even tread wear through balanced pressure distribution. For normal urban driving, motorway travel and longer summer journeys, the combination of responsive dimensions and touring-oriented construction makes the Cinturato P7 a practical road choice.

Who should choose this Pirelli?

The Pirelli Cinturato P7 MO 245/40 R17 91W is most appropriate for drivers with a compatible Mercedes-Benz application that specifies the MO marking and who want summer-road handling, wet-weather control and predictable touring behaviour. It is not a winter tyre and should not be selected for severe snow or off-road use. The exact configuration is also not run-flat. The supplied manufacturing year is 2024, while the country of manufacture for that particular production batch is not confirmed.

For customers comparing Pirelli Tyres, this MO specification should be distinguished from other Cinturato P7 versions in 245/40 R17, including different load or speed ratings and run-flat variants. Dwbtyres buyers should confirm the vehicle manufacturer's approved tyre specification before fitting.
