I really dont want to run tube tires on my car and just want the best I can get that dont really require tubes on a ~350rwhp car. Anyone run ET Streets without tubes and not have an issue?

 

I've run ET Streets and Hoosier QTP's with no tubes. You have to watch the air pressure very carefully, because they do lose air faster. I also wouldn't go below 12psi or so without a tube. And rim screws might be a good idea, since there is nothing but the tire bead friction holding the wheel inside the tire and keeping it from rotating.

 

I'm probably not going to run much less than 24 psi. They should be nice and sticky at that point.
