Tire sizes

[Hugh Hamilton]

I thought we reached a consensus a while ago that 120/70 in the
front and 180/55 in the rear was the ideal setup for the GTS. When
did people start going back to the 170/60 for the rear?

I'm on my 5th set in the 120 and 180 size (Dunlop 207) and haven't
noticed any poor handling traits as the tires wore.
