I've been working on my 50 coupe for a couple years now. Way back then I bought 4 of the cheapest 15" trailer tires I ever saw, so all this time I haven't had to blow up tires to move her around. And they look good. Now I'm getting to where I need to tag the car and go to town. I've probably got 20 miles on her ramming up and down the road out front of my shop, seating the rings, etc. Car drives just fine..........surprisingly so- all new steering parts, etc. What about these tires? I tried to read up, never found real world info. Might be illegal? Why? I'm a bias tire guy, don't want radials. What about these tires on my car? I can always put em on one of my ragged ass trailers. Thanks for any info!
