There are a number of performance and aesthetic benefits to installing aftermarket wheels on passenger vehicles—and those same benefits extend to trucks, too. Even SUVs. Aftermarket truck wheels reduce weight, improve acceleration and braking, add rigidity and increase the brake cooling process.
And they look darn cool, too. Check out these best-selling truck rims:
Ultra Rogue Machined w/ Black Accents
Granite Alloy LK1 Bright Silver
Mamba M2 Machined w/ Black Accents

The balance issue could be from either the tire or the wheel. A shop with a road-force balancing machine would be able to tell you exactly how balanced or not the wheel/tire combination is.
It is possible that the wheels and tires are perfectly balanced, but the wheel is not centered correctly. If the wheel is not hub-centric, and does not have a hub-centric ring, they must be carefully torqued down before the vehicle is set down, in order to keep them as centered as possible.
Hope that gives some ideas to get started on figuring out what is wrong.
