These tyres were obviously designed for those who like jam with their TOST.

They stay inflated but jam in the hub as one side comes off A solution seems to be is, at assembly and before inflation use a little contact adhesive on both the metal rim and the tyre rim then inflate slightly and leave overnight. Next morning add a bit more contact around rim tire join and inflate. This is a method used by racing bike people to keep tyres on the rim. You may care to dilute the glue a little or get the stuff that the tire man uses when he fits your tubeless tyre to your car rim. If you have had this problem you might make contact with me and try this method. While on TOST I have noticed some of the very old 500x5 tost hubs with drum brakes have 2 springs the SAME SIZE. These old types are more prone to have the brake shoes draging a little. Later 500x5 hubs use ONE LARGE and ONE SMALL sping and these cause much less problems and I consider an upgrade is worth while. And while on TOST brakes they are for use in emergencies and should normally only be used at just the end of the roll. As TOST call it "Cowboy" use of brakes can generate a huge amount of heat especially with disc brakes. You may have read of a Duo Discus in UK was towed out to field WITH DISK BRAKES ON and the aircraft caught fire and was DESTROYED!!!!. Instructors may keep this in mind at check flight time as if they are overused and pads go through to the rivets, new brake disks are very expensive and can only be resurfaced once from my experience. I do have disc pads if needed and would recommend the use of the correct re riveting tool. If anybody knows of another source of 210x65 (can be called 250x3) other than Continental then they might let me know Regards and you just may see me around gliding a bit more after a 4 year break!!

I do have the special low profile 6mm metal lock nuts used on releases. Many special wheel/brake TOST parts are stocked all at a price unfortunately.
