When I have time, I'm going to try the wheels and tires from my Grizzly 660. I have 14x7 STI HD2s, with 30" Monster Mayhems on them. I think they are 4+3 but not sure. I will probably run them until I can afford to get more tires for my Z. When I get more tires, I'll probably keep the stock wheels, because they are as nice as any aftermarket wheels.
