If they have the same or close diameter to the original equipment and are not heavier you should ride and handle fine. It they are wider they will impact fuel economy but that might be slight enough to be unmeasureable.

I am pretty tough on unsprung weight. In my vw diesel wagon when I needed tires, I went from the original 17" rims to 16" and used tires with the same diameter. ... Actually went a bit narrower I think. With the new rims and new tires I saved 4#/ wheel. That is enough to feel. I saved enough on the tires to pay for the smaller wheels and gave the 17s to my Indies who gave me some credit on my account.

Lots of folks put on wider tires thinking they will make the car better, and mostly they probably will not notice any difference in handling and they will like the more butch look.
