In the late 80s, Mini-Truck dudes were running 195-50-15 tires on 9 inch wheels and 205-50-15s on a 10 inch rim. This stretch look was made possible by a machine known as the "Master Blaster"...It provided a rapid shot of air pressure to inflate and seat the beads!
I wasn't into the Mini-Truck scene but I do remember the impact they had back then.
