You're being BS'ed. If their work doesn't fix, or if it worsens a problem, it's up to the THEM to fix it and correct the problem at THEIR own cost. Tires being used have virtually nothing to do with alignment, definitely a load of BS especially considering I've ran several different tires, as well as an altered suspension system on my car. Also not all Hondas come with Michelins on them. When I got my Civic in Dec. of '99, almost all the other Civics on the lot came with Firestones, mine came oddly with Dunlops, though they were installed at the factory just like any of the other cars there on the lot.
