GMC 1500-wheel offset question
 

I have an 03 Sierra, 1500 Z71, with fender flares and mud flaps. Levelling kit and add a leaf installed about 2 yrs ago. Looking at rims/tires. Stock 16's are +29 offset and from the front and rear, look a bit narrow...i'd like to widen the stance a bit, but not have the wheels stick out too much...especially at the front. Zero offset wheels add about 35 mm. Has anyone installed zero offset wheels on their truck..? How does it look. Any other advice?
cheers
