[A4 1.8TQ] Tire Swap?

[l.leung at juno.com]

I'd check the room behind the wheel and by the fender lip, I'd rather doubt clearance will be a problem, since sport's have 225/40-45(?)-17's. The car will ride a little higher and the speedo will be off by maybe 5% (don't have the time to calculate right now) and the car will possibly feel a little sluggish from the effectively taller gearing, but I don't think that there are any other adverse consequences. If you are living where deep snow is occasional, the better winter compounds will probably help on slushy, icy surfaces more than the reduced width. I think it will only be an issue if you are trying to plow your way through deepish fresh fallen or hardpack snow.
