Here's a good story about Honda.
My sister bought an Odyssey about 8 months ago. Her OEM Symmetry's were wearing down at a ridiculous rate. She caled Michelin, but they wanteed nothing to do with her.
She then called her dealer who got the zone rep involved. Supposedly, the OEM Symmetry's are supposed to be good for 30.000 miles. Her's were already more than 1/2 gone and she only had 7800 miles on the car. Tire pressure and alignment were good.
The Honda rep agreed that the wear was too quick. He had the dealer install new (non OEM) Symmetrys on my sister's van.
No cost to my sister.
Not everyone has a bad experiemce with Honda's Zone reps.
