Any advice on winter tires would be helpful; I live in the North west although we often get zero snow fall it is not unusual to have lots of snow either so I have made the decision to buy winter tires . Unfortunately all weather Nokian' are not available in the K900 size 245/50/18
I didn't realize the V6 had 18" tires and wheels.
My V8 has 245/45/19 on the front and 275/40/19 on the rear
not good for rotation but good traction , just not in winter.
Try and get winter tires for these. lucky I'm in Arizona and
don't need winter tires
Look on tirerack.com for ratings and pricing of winter tires
