Yes, I think a little air in the tube during installation may help. Also, after setting the bead inside the rim air up to 15 or 20 psi then deflate completely before pumping full pressure to fully seat the bead. The idea is to allow the tube to relax and untwist or unfold if that has happened and it only takes a minute. Deep vee rims and long valve stems have created problems of their own. And now that it's not easily get tubes with stems less than 50mm they end up looking like crap on shallow traditional box rims (MA2 and CR18's).
