Grand Touring All-Season run-flat tires provide temporary self-supporting run-flat mobility for a distance of 50 miles at up to 50 mph, even after a puncture has allowed complete air pressure loss. They are for drivers who want a combination of a sophisticated appearance, competent handling and H-speed rated (or higher) durability, along with all-season traction, including in light snow. Grand Touring All-Season run-flat tires branded with the M+S symbol and are often used as Original Equipment (O.E.) on sophisticated coupes and luxurious performance sedans.

O.E. Grand Touring All-Season run-flat tires are typically purchased as direct replacements for worn-out pairs/sets of the vehicle’s original tires. They can also be used for other vehicle applications in complete sets of four or axle pairs if available in an appropriate size, load range and speed rating to match the existing O.E. run-flat tires’ performance category and specifications.

NOTE: Run-flat tires are only recommended for vehicles that are originally equipped with self-supporting run-flat tires and equipped with a tire pressure monitoring system.

Though they cannot be labeled as run-flat tires, tires branded with MOExtended or MOE on their sidewalls offer run-flat-like characteristics by delivering limited temporary extended mobility after a puncture results in complete loss of air pressure. Because MOExtended or MOE tires do not have the same speed and distance endurance of conventional run-flat tires, they should not be substituted in any situation where a conventional run-flat tire is required. To confirm what your vehicle needs, check our Original Equipment tire listing for your year, make and model or see your vehicle owner’s manual.


  1. Having about the same experience with these tires as most other MB owners on this review board. My first experience with run-flats. Ordered Luxury model this time for slightly less bone jarring ride and even sized tires front to back. Also ordered 18′ upgrade which dealer failed to mention were mixed tire sizes. Won’t make that mistake a 3rd time! Had two previous C300 4Matic sedans (2010 and 2013) and the rear tires wore out before the fronts. On this car, a 2015 C300 with run-flats, the front tires are a 4/32″ at 29000 miles; acceptable for this car. Rear tires are 10/32″; exceptional for this car. Dealer says must put same spec although any brand on car before lease turn-in, so I’m am just going to replace fronts with same tire. Notice a lot of hydroplaning now that fronts are this low. Never had this issue before.

  2. Bought as a replacement for the awful Goodyear LS2 that were on the vehicle. I have Continentals on a Saab convertible and they have been great tires. Went with these as an experiment and haven’t been disappointed so far. Road manners are good and noise has been excellent. Not overly responsive but wasn’t expecting much from a grand touring all season. Snow performance has been less than I was expecting and will most likely switch to a true winter tire next year. Where these were brand new at the beginning of the season, they were okay for the little snow we had in Massachusetts this year. Overall a quiet comfortable ride even on bumpy back roads with broken pavement.

  3. Just had my 20k service completed. Front tires center tread is 2mm, rears are 6mm. Heavy and excessive inner and outer chop. So way the tires should be this bad after 20k! Won¿t be buying these again. Going with Michelin !
