Have you considered "sealant" or "flat-proof" or other stuff to prevent a flat tire?

 Just read a tale of woe from a motorhome owner that appears to have been sold a tire treatment that caused nothing but problems. Names have been changed to protect the "innocent".

"We purchased "anti-flat" tire sealant for the 6 tires on our motorhome, to provide some protection from tire leaks on trips.  Our RV has had vibrations running at highway speeds, and based on forum feedback, it was recommended we try a "road force balance" on the tires.
We took our RV to "Billy-Bob-Jo's tire Emporium", which has road force balance machines - and they were unable to balance the tires - the machines got a different reading after each spin. They assumed their machines couldn't handle the motorhome rims.

 Then we took the motorhome to the nearby dealer for the company that made the RV chassis (since the front two tires were no longer properly balanced), and they called us about the "goo" they found inside the tires - because they were also unable to balance the tires.
Once they removed the tire sealant (about 45 minutes per tire), they were able to get all 6 tires balanced.  It cost us around $1000 for the "anti-flat" treatment and another $500 to get the treatment removed and the tires balanced."

Then the RV owner asked  "Has anyone encountered balance issues when using tire sealant???"  and then added  "If we don't have any vibrations on the next road trip, we probably won't put any sealant back inside the tires."

  Clearly the material used either was in-appropriate or improperly applied. Also I do not understand why the owner felt it was necessary to even use such a product rather that use a TPMS and sign up for road service and save some money never mind avoid the aggravation of bad ride and lost time.
