Garage Cabinets, Garage Storage, and Garage Organization

I love the look of the Five Hundred, with the standard wheels.
has anyone in the Canada found a good place to buy alloy wheels and tyres?
anyone else changed the wheels?
does it affect the ride? as the ride is quite firm even before you change to bigger rims?
any advice or experience?

I think the Five Hundred with it's larger road biased tyres rides a lot better than a std wheel/tyre combo.
Tyres make a huge difference to a cars ride, the standard factory ones tend to be a bit hard in compound, the five hundred gets some nice continentals.
