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.

  1. This set of tires is on a Mopar13 Dodge Dart, 1.4L MultiAir front wheel drive vehicle. I’ve driven very little in snowy conditions and none on ice or snow packed roads. I don’t believe the amount of space between the tire tread and the wheel well and low ground clearance would be good conditions for this auto. It was relatively easy to break the tires loose in acceleration when accelerating fully after the turbo spins up, judicial use of clutch and accelerator allowed plenty of traction in acceleration for dry conditions. I was very impressed with the cornering ability of these tires in dry conditions, I have cornered hard while braking and accelerating and never once did I lose traction. Also I never have experienced hydroplaning or loss of traction in wet conditions but I always drove with caution on wet conditions. Road noise was one thing I felt could be improved on but this may very well be the soundproofing of the auto and not the tire at all. The tires are what were on it when I bought it, I rotate tires every 5,000 miles; @ 26,000 miles I have about 1/32 before the tread bar is exposed. The tires have run true, I have not had to re-balance the tires due to tread wear, the tires have maintained balance as the tire wears down. After this last rotation of tires I noticed increased road noise and vibration, which I would actually describe as “thrumming” sensation. I also have never had a flat or any blistered sidewall. I am torn between purchasing another set of these or the Michelin PRIMACY MXM4 ZP – SIZE: 225/40R18. There is approximately a $25 dollar difference per tire with the Continental being more expensive.
