Nice gently used set of Tyron Multiband wheel safety bands. Keeps the tire on the rim if you have a blowout so you can safely get to the shoulder without your motorhome veering across multiple lanes. These are popular in police/military vehicles and have been proven to help keep your vehicle in control after a sudden blowout.
These are for 22.5" rims and are the 88 mm wide bands, almost $1000 new. They are similar to a beadlock or runflat design but slightly different.
From their website:
TYRON® wheel safety bands are a simple yet effective solution to the danger and inconvenience punctures, blow-outs and under inflation. With TYRON® fitted, you have the piece of mind knowing that you can remain in control and mobile, should your tire deflate – at any speed – on any surface.
CONTROL With the tire kept in place by the TYRON® safety band, steering, braking and cornering control can be maintained at any speed after a simple puncture or an instantaneous blow-out.
SAFETY greatly reduces the risk of accident and fatality through loss of control after tire deflation.
MOBILITY provides traction plus a short runflat or get-out capability. The driver can continue to a safe place to change the wheel.
