2003 V8 4-Runner with Michelin 265-70-R16 Cross-Terrain OEM tires. They lasted 80k miles, wore evenly with periodic rotation and balance. Driven mostly by my wife, an ez driver. At replacement time they were not available anymore. Replaced them with Michelin Latitude Tour's of the same size. These new tires will not quite make it to 40k (80k guarantee) with the exact same driving conditions and drivers, myself and my wife. Evidently these replacement tires are giving other drivers the same problems. The tire store is offering a pro-rated replacement but I'm wondering if I want to end up with another set of tires that won't last. Driving is almost all street and some unpaved roads but good condition, no ruts or other obstacles. No snow, ever and very little rain, some light weight towing but no hauling heavy loads. Any suggestions....
