No. Ground is better IMO, even with air tools; just have the lug bolts snug before lowering car. Weight of the car rests on the hub's 'ring', not on the bolts themselves. And rubber is flexible for the minute movement after tightening. Actually, I've never seen anybody tighten wheels to spec in the air in my 47 years. Plus you'd need somebody inside the car to put the brakes for the front wheels on RWD cars, especially without air tools. No need to be that anal .

And the opposite when removing a wheel: loosen bolts on the ground and snug them back until wheel is in the air. And it's best to tighten them to spec in 2 steps, both times in a criss-cross pattern. I do 45 and 85 on the M3, and 40/80 on all others. Take care.
