I don't know the answer but I also don't know why anyone would think of reducing the rear contact patch!

hmmm, you are assuming the contact patch is reduced of course, there ins't a great deal of difference between the contact patch of a 150 compared to a 160 and different manufacturers may have a different profile and actually have more contact patch. Narrower tyres benefits are faster turn in and better wet weather grip,

Lovely contradiction there!
