They are bias-ply & therefore ride a bit rough, follow ruts and get poorer gas mileage than a radial. It says "For track use only" on the sidewall.
It's been discussed at length that the lettering is horribly applied & turns brown very quickly. I've re-painted mine by hand three times already & will need to again soon.
I'm not sure how to post a picture, but you can look at my car in my photo gallery (I think) & see what they look like new.
