bias ply tire memories.

Without suregrip, my parents new 1971 383 auto with open 3.23 rear gears (factory equipped G60-15 Polyglas GT) was spinning a tire off the line at Fremont Raceway. A guy walked over to me and suggested I over-inflate the tires for better traction (quite opposite to my ideas at the time). It worked, and it took off without the previous wheel spinning!
