I would have thought that some of the rear tyres in the 80's would have been wider but I don't have any numbers.
I was speakign to someome once and he told me that they were so wide that the tyre itself would twist like a differential from the outside edge to the inside edge.
they played with various rim configurations as well to combat that ,,, rims wider than the tread and visa versa...cross section looked like a parallelogram.
To achieve anything, you must be prepared to dabble on the boundary of disaster.”
