Our older style wheels (still for the "new" 1992+ chassis) are an ugly gray. A generous friend painted the last RV we had, and we painted the wheels too. Looked good, but had to be touched up whenever I did any work involving the wheels. We painted them in place on the coach, so Lugs, Hubs, etc. were painted. Those wheels had short metal valve stems with braided extenders on inners only. Did the outers with an angled gauge and angled chuck. But those old wheels (1983 chassis 16.5") had real Hand Holes like the pix above.
The newer coach (signature) has the "eight round hand holes" which might be hand holes for an infant. This made checking very difficult with the rubber stems and little metal extensions the prev owners had. I said "extensions" since that's all they were. The ones for the outer duals had a bend to bring the cap out the baby hand hole. Wheel simulator (Dicor) holes made the holes even smaller. I hated it.
And I was a holdout on Tire-Man or Borg Dually Valves. Bill (Westronics), one of our Moderators, said "You'll love them" and was completely right. I got some Air-Through caps to go with my Borg valves and just checked six tires in well under two minutes. And none of the six needed air. You lose more than you think with inferior valves and extensions/extenders.
I got my Borg set very cheap, and the cost to install/balance was around $75. That was with me blocking the RV up and bringing the wheels into the shop in my van. So I got it done around $150 for seven wheels. Somebody says $200 above, probably reasonably accurate. A shop quoted me $185 for the rear duals, parts and labor. Sounds high, but SO worth it.
