ok, i have an 06 S model, and here's some things you need to know:

no offroading...at all!
some highway driving, like 35-40% of my miles
mostly in town driving

pretty soon it'll be like 90% in-town driving.

i want to upgrade in size mainly, but don't want to have to lift my X or do any suspension work to make them fit right.

i'm also wanting a more rugged tire look, but not a 100% offroad tire obviously.

i need some suggestions/pictures. i'm new to the whole "bigger tire" thing, as i've only had a car with 18's and low profile tires before this Xterra.

thanks for any help guys!
