Hello G37 proud owners,

It is been a year driving my 2013 G37X sedan.. day one i am loving the way it handle, power and how nimble.. i live in Boulder foothills of great rocky mountains, i drive in out of mountain almost every week through the year.. it is so amazing how it handles the sharp high altitude mountains ( drove upto 14k plus feet) to 6k feet in Denver metro area..

As we getting to winter and after few snow days felt i should change the existing factory tire and wheels. I dont have much budget constraint, i just want to install good tires and wheels...
after talking to couple of people in dealer below or my thoughts..

1. Upgrade from 17'' to 19''
2. Should i go for all season or both summer/winter tires
if i go for season tires
a. Pirelli p Zero for summer
b. Bridgestone Blizzacks or Pirelli sotto zero.
3. if i go for all season
Continental Extremecontact DW 06 with size 245/40R19 98V XL..

So please suggest me with best tires preferably all season tires and also the best wheel specs. I drive silver color car, so would like to go with metalic gray color wheels.

any input is appreciated , looking forward for your response..
Thanks..
