During routine oil change visit after long trip, was notified of extensive wear & damage to 3 of 4 tires. One had strip of rubber wrap around the axel, bust the boot & brakes & bent the axel. Another had @ 5x4 inch piece of rubber missing, steel belts were shining. Third tire had areas of separation all around the tire, more steel belts visible. Luckily they held pressure & didn't blow out. Have always kept them rotated & balanced. It'd been 6 months since they'd been rotated/balanced -- and only 6000 miles. One service guy mentioned "outer edge wear" on them, but the service manager, after looking at the remaining warranty/miles left, said that the tires were supposed to wear like they were. The tires were 4 yrs old & had @ 60,000mi. On them.
