Valve stems oposite are the way a profesional does things , ease of airing and always a uniform purpose, i cant and won't belive a rear tire needs to worry about balencing at all, expecially in a deuce! I know how high teck they are and any little tweek will throw all that technology out of sync, he he he. In all my vehicles I only high speed balence the fronts, cars trucks,4 wheel independent suspention is different of course. when i rotate i then I then high speed balence the tires going on the fronts, thats when they need it, and they wont be balenced if one did it when they were put on and drove 3000miles and then rotated , U will see the difference when u do it, Flat spots are much more common in bias plys, and/or at least they take longer to run smooth again.Always exorcise ones tires, never let em sit for more than a month and not the same side facing the sun also. protect those babys too, use a UV sun block spray also ,AND as for guys pushing the speed of these antiques, it is important to balence the fronts of even a deuce, as some guys live to make things go faster, , but a regular driver knows a little shimmy at 40 for a few seconds, is usually do to no balence and just exagerated by road conditions, surface type i mean..some are long wear paths in the road, one will learn all the typres of road wear and condition of the road make a diffenence and after many miles in a M series, smooth is smooth, and for me they shouldnt go that fast that they need it, although i did it in one truck to see how i like it,i like a deuce to be a deuce but thats me, and i change my views yearly, I also belive that much air will only make a difference in the 5 ton vehicles, i do think they like more air for a more controled ride though. but thats relative too. ...Randy
