In owners' own words
Verbatim excerpts from complaints filed with NHTSA about Yokohama. Reports are published by NHTSA as filed and are lightly cleaned here only to remove intake codes.
THE CONTACT OWNS A 2009 TOYOTA RAV4. THE CONTACT STATED THAT THE VEHICLE WAS EQUIPPED WITH YOKOHAMA G91 TIRES, SIZE 235/65/17(NA). THE CONTACT NOTICED THAT THE TIRE TREAD WAS PREMATURELY WORN ON ALL FOUR TIRES AND ALSO EXHIBITED SEVERAL CRACKS. THE FOUR TIRES WERE REPLACED BY AN INDEPENDENT TIRE CENTER. THE MANUFACTURER WAS NOT NOTIFIED OF THE DEFECT. THE APPROXIMATE FAILURE MILEAGE WAS 18,000. THE DOT NUMBER WAS UNAVAILABLE.
WHILE DRIVING APPROXIMATELY 55 MILES HR IN 820 I EXITED RIGHT ON THE WEATHERFORD EXIT AND WHILE IN THE TURN THE BD SIDE TIREBLEW OUT AN THE TREAD HAD COME OFF CAUSING MY CAR TO SPIN OUT OF CONTROL AND GO DOWN AN EMBANKMENT IN WHICH WE ALMOST FLIPPED MY CAR BEFORE WE COULD GET IT STOPPED IN WHICH IT CAUSED EXTENSIVE DAMAGE TO THE REAR DRIVERS SIDE OF THE VEHICLE.
YOKOHAMA TIRE AVID ASCEND 185/55R-16 SIDE WALL HAS DEVELOPED SIDEWALL BULGE AND POTENTIAL FOR CATASTROPHIC FAILURE AFTER MINOR BUMP AGAINST CURB. THIS OCCURRED TWICE ON SAME VEHICLE WITHIN A 12 MONTH PERIOD. RECENT EVENT REPORTED BELOW WAS ON A TIRE WITH LESS THAN 15K MILES.
THE NHTSA BY TELLING TIRE DEALERS THAT THEY CAN NOT INSTALL MY MOUNTED SNOW TIRE BECAUSE THEY DON'T HAVE TPMS SENSORS HAVE MADE DRIVING IN THE WINTER MORE DANGEROUS AND UNSAFE FOR ME. THE SYSTEM IN MY SUMMER TIRES HAS BEEN INOPERABLE FOR 2 YEARS AND YOU KNOW WHAT HAS HAPPENED... ABSOLUTELY NOTHING. THE COST OF THE SENSORS IS VERY HIGH AND IF YOU GUYS WANT ME TO HAVE THEM SO BADLY, THEN PAY FOR THEM YOURSELVES. THIS IS JUST ANOTHER EXAMPLE OF NANNY STATE GOVERNMENT TRYING TO MAKE IT LOOK LIKE THEY ARE DOING SOMETHING TO JUSTIFY THEIR PATHETIC EXISTENCE. SO IN SUMMARY YOU ARE ACTUALLY MAKING THINGS MORE DANGEROUS FOR DRIVERS BY DENYING TIRE RETAILERS FROM INSTALLING SNOW TIRES ON MY VEHICLE BECAUSE THEY DON'T HAVE A WORTHLESS SENSOR THAT DOESN'T DO ANYTHING TO MAKE DRIVING SAFER FOR ME. I HOPE YOU GUYS ARE HAPPY WITH YOURSELVES.

Yokohama geolandar X MT: what the numbers tell you
Manufacturer treadwear data for the Geolandar X MT is not publicly listed. This is common for OEM-only or track-day tires that don't carry a US treadwear warranty.
