A press is nice, but not necessary. A BFH and a steel drift work fine if you have the patience for it.
In a pinch, a BIG nut (used as a spacer) and an acorn lug nut (open back) turned backwards so the flat edge hits your spacer will work to 'pull' the studs into position. You'll still want to visually verify that the stud has seated so it doesn't loosen up later. Also, if you're going to do this, some lubrication for the threads (like antisieze) is a must.
Whatever you do, DEFINATELY RETORQUE THE LUGS SEVERAL TIMES! Drive it to work, retorque. Drive it back home, retorque. Do this three or four times to make sure that the lugs are fully set in the hub assemblies and the lug nuts are correctly tightened. Once the wheel studs are well set, you'll not need to retorque as many times for future wheel removals.
