I'm the owner of a Coachman Amara 2003 fitted with the above tyres a couple of weeks age I headed off to my local CL. Once every thing was connected and set I went to put on my wheel clamp on which I could not do it suddenly did not fit. on closer inspection it appeared that my radial tyres had turned into what i could only discribe as the sane shape as a crossply (only about 2 inches of tread touching the ground). I have taken my caravan to my dealer where they have been promply changed. They have told me they have had three other instances of this. Please check your tyres regulary especally if there HANKOOKS. Could some what explain why this may have occurred??. I religously check my tyre pressures everytime I go away.
