Dismountting is not worth it. I do on occaision lift off ground to spin looking for runout and to look at brake pads as well as wheel bearing rock on fronts. On the road, I also check casing temps which may show issue sooner than pressure loss.
I mount/dismount and balance all other tires myself. I do not do the RV or the 20" SUV tires, low sidewall aspect is tough without tire machine. The 16" on Altima and drag slicks are easy.
I will continue to watch how they perform. May consider replacing next winter.
