For an aggressive looking rim brand, look at ATX. They make some really great rims that I may be going with. They come in all different accents and styles, one of them are sure to be the ones you want. As for tires, the best tire I can think of that looks aggressive but doesn't drive too aggressive is the Goodyear Duratrac. Looks very mean, light weight, you can get it in a 35", and will do great for daily driving. I think a 17 black ATX or evena Black Rhino (another rim company) rim with some silver accents wrapped with 35" duratracs is a a very aggressive and great looking setup. And, if you guys so desire to hit the trails some day, those tire will do fantastic. They are an all terrain, but perform almost close to a mud terrain off road, but also do awesome in the snow and rain, unlike many mud terrain tires.
