Bias ply tyres,cobbled
wet Glasgow streets
and tramlines = Nightmare!

I used to drive virtually the entire length of South Street in Glasgow with my bias plys tramlining,I hardly needed to touch the steering.
Thankfully the tracks followed the road.
I've had way too many scares with these a few years back.
I'll stick with radials thank you very much....
I'd rather loose a bit of originality for safety any day.JMO.
