Regulations Section | Federal Motor Carrier Safety Administration
Are you sure about criminal charges being possible for non-DOT tires?
I am in Nevada and the state law / DMV here also does not specify the need of DOT approved tires just like Federal regulations.

However in case of motorcycles there is a clear requirement to run DOT approved tires.
CA state law requires DOT tires - so it varies from state to state.
I am still contemplating getting another set of non-DOT, I personally trust them more for the type desert running I am doing, but still trying get a better understanding of the legality.
There are lots of anecdotal stories and opinions out on various different forums but they usually start with "I heard" or " I know a guy" but I haven't been able to find any hard facts of lawsuits regarding race tires in car accidents. I don't really know how to search for this stuff - but maybe someone can guide me in the right direction.
I also would love to find some verifiable situations where an insurance company was successfully able to deny a claim because of running race tires. I just can't imagine a situation in which an insurance company could successfully deny a claim just because of the tires not having DOT approval, without the tire being the clear culprit. Not saying they wouldn't try...
Tire manufacturers are not allowed to sell tires the public without DOT approval by law, but my current understanding so far is that at least in Nevada there are no laws to prohibit running such tires as long as they meet the federal and state guidelines.
EDIT:
Actually found a great resource with good info on local state laws:

Shows all the different state laws on mods for vehicle. WIsh I would have found that a long time ago! Time to find a new insurance company for me.
