US Question: Tire (road hazard) warranty with car?

[Ferguson]

For those in the US - did you get a Michelin warranty with the car when you bought it?

My recollection in past car purchases is that they give you that paperwork. I explicitly asked for it, was told they never provided it.

I explicitly asked if it covered road hazards, and was told that it did not and "no tire warranty does".

The Michelin web site indicates otherwise, as has been posted here, so when the sales manager called to ask if I was happy, I said "yes" but I asked again. Same story, and (of course) same pitch for their extended tire warranty. But he promised to check and get back to me (has not).

I am wondering if this dealer is purposely hiding the fact that there is some limited road hazard warranty from the tire manufacturer to better sell their tire warranty. Or am I just paranoid?

What did other dealers do, or say? Anyone get warranty paperwork with the car? Or ask about road hazards?
