Some places here it's against the law to use studs.
When I was living in Tennessee I bought a delta 88 with a 350 Chevy engine. The top was delapidated vinyl that I tore off and pressure sprayed the old glue, it started looking pretty good.
The guy must have been in a bind trying to please a woman that never would be happy. I had no clue till after asking if he could take a bit less than was stated in the ad, he said ok, then asked me to sign a paper verifying the changed price.
It had studs on one axle, I think the back, I didn't want to buy new tires either so I drove with them.
That thing would sure whine on the highway
