2010 VW Golf 17 or 18" rims question.
 

I just bought a 2010 VW Golf Trendline Package and need some help:) I was thinking of putting 17" rims or maybe even 18" on this car but I have a few questions:

• I saw that the factory upgrade includes 17" x 7" "Portos" rims - does anyone have these and if so, what is the offset (ET) on them???

• What have you 2010 owners been putting on your Golfs (diameter, width, ET... without adding spacers or anything too crafty)?

Thanks so much - I know nothing about cars, tires...
