MICHELIN LATITUDE TOUR ALL SEASON TIRES HAD SIGNIFICANT CRACKING ALL THE WAY AROUND THE CIRCUMFERENCE OF THE TIRE ON THE SIDEWALL NEAR THE TREAD. TIRES WERE 2 YEARS OLD. SOME SUPERFICIAL CRACKS OTHERS WERE DEEP AND WIDE. 65,000 MILE WARRANTY, ONLY 25,000 MILES ON THE TIRES. SIZE P245/65R17 105T ORWL. ALL FOUR TIRES HAD SIGNIFICANT DAMAGE.
AT 42,039 MILES ON A 2011 DODGE GRAND CARAVAN MY WIFE EXPERIENCED A SUSPICIOUS BLOWOUT ON A 225/65X17 MICHELIN ENERGY SAVER A/S TIRE WITH A 100T RATING. THE DOT # IS: M33T 00KX 1711. THIS IS A 65,000 MILE TIRE. NO FOREIGN OBJECTS WERE STRUCK. THE AIR PRESSURE, TIRE ROTATIONS, AND ALIGNMENTS WERE DONE IN A TIMELY FASHION. I NO LONGER FELT SAFE ON THESE TIRES AND REPLACED ALL 4 WITH ANOTHER BRAND. THIS WAS CLEARLY A MANUFACTURERS DEFECT.
THE TIRES ON MY 2009, MERCURY MARQUIS, ARE DRY ROTTED. I HAVE ALSO NOTED THAT THERE ARE HOLES IN THE SIDEWALLS ON ALL OF THEM ALONG WITH A LARGE BULGE IN THE RIGHT PASSENGER, SIDE TIRE WALL WITH A TEAR AND LARGE HOLE WHERE THE BULGE IS. I HAVE BEEN TRYING TO LOOK UP ON THE WEB SITE TO SEE IF MY TIRES ARE IN THE RECALL LISTS WITH SOME DIFFICULTY. I SINCERLY HOPE YOU CAN HELP ME WITH THIS PROBLEM AS I AM AFRAID TO DRIVE NOW AND MY HUSBAND HAS SEVERE PARKINSONS DESEASE AND I AM AFRAID SOMETHING IS GOING TO HAPPEN TO HIM. THANK YOU! I WILL BE LOOKING FORWARD TO YOUR RESPONSE.
ALL FOUR TIRES ON 2011 MERCEDES E550 HAVE TREAD SEPARATION. TREAD SEPARATION IS OCCURRING ON THE BACK SIDE OF THE TIRE AND IS UNKNOWN UNTIL THE TIRE BEGINS TO LOSE TIRE PRESSURE. TIRES ARE ORIGINAL EQUIPMENT MICHELIN RADIAL X TIRES. FAILURE BETWEEN 38,000-40,000 MILES.

Michelin pilot sport cup 2 connect 240 305/30R21: what the numbers tell you
Manufacturer treadwear data for the Pilot Sport Cup 2 Connect 240 305/30R21 is not publicly listed. This is common for OEM-only or track-day tires that don't carry a US treadwear warranty. No mileage warranty is published for this tire, which is typical for performance summer and track-day rubber where the manufacturer doesn't make wear-life claims.
Cabin noise data for this tire is not published by the manufacturer. As a general tire built for the passenger segment, the Pilot Sport Cup 2 Connect 240 305/30R21 is positioned against direct rivals within the same category. Comparing it to a tire in a different category (e.g. summer vs all-season) makes the spec sheet misleading because the design targets are not the same.
The Michelin Pilot Sport Cup 2 Connect 240 305/30R21 has been part of Michelin's catalog since its introduction, and remains a current-production model.
