Our first set of tires with this coach, included all 8 tires/wheels being spin balanced, and we have Centramatics on each axle.
Replaced the steers about 6 months ago to an sudden encounter with pot holes
!. Again had the tires spin balanced, and retained the Centramatics.
Will be doing the other 6 tires in the near future, and will probably not balance the drives or tags this time around, as the Centrmatics will be retained.
I always make it a point to pay close attention with a new set of tires the first few hundred miles. If I notice any out of round/egg condition, or feel the tag or drive are not as smooth as I prefer - I'll then go ahead and have the tires balanced too.
Tires are on coaches for 5-10 years, depending upon the owners preference for replacement schedule. Even at 5 years, the cost of a spin balanced spread out over that period - is not that much of a hit
Noting wrong with the beads, they do a fine job. And as some have noted, some are worthy of being transferred to new tires too.
Best to all, be safe, have fun,
