There were quite a few cars with 16" wheels. Should be able to find a decent tire to work for him. For what he wants to do he doesn't need a low profile tire, just a good radial with the sidewall he likes. He wants a cruiser for the daily highway commute that responds when he steers. A little bigger on the torsion bars, good factory type shocks (no need for high $$ stuff) front and rear sway bars, rims and tires of his liking, moog offset UCA bushings, and a firm feel box and he will have exactly what he wants, a well handling and responsive cruiser. I would recommend at least 10.89 discs over drums but 11.75 would be better if not already on the ride he picks. He won't be on road courses, just normal driving. He would be more than happy with what I outlined I would think. I am no expert but that what it sounds like.
