Something peculiar to an A2 is that the hubs are not the same size as the hole in the wheel, which makes it act like a hub centric rather than a stud centric setup. What I found that works pretty well is to lift both sides of one axle off the ground enough to be able to spin the tires. You'll have to release the parking brake if its on one of the rear axles, so make sure you chock the wheels. Have someone else spin the opposite wheel slowly while you run the nuts down a bit at a time so that the studs center as you tighten them. Once they're in place, set the parking brake and tighten the lugnuts to the correct torque. It has been my experience that just torquing the nuts down will not center them on wheel holes correctly. This is what has worked for me in the past, anyways.
