quattro digest, Vol 1 #3971 - snowtire size

[l.leung at juno.com]

BTW, the correct snow tire size for an A4 on 15's (assuming they
clear the brakes) is  195/65-15. This also opens up more options
than 60 series snows. They're also mushier in the dry, and in non
hydroplaning conditions,less effective in the wet(as all low rubber
to void ratio tires would be in non-hydroplaning conditions. I'd
bet that surprizes a few...)
