Hi folks decided to change my rear TKC80 for a Heindenau T60 scout, removed the Tkc 80 no problems then the fun began! after a struggle managed to get one side of the scout on the rim. inserted the tube then tried to get the rest of the tyre on the rim got to the last 10 inch of tyre and now way was it going on It got so tight that the bead began to tear at the lever so eventualy I had to release the tyre all the way round and try again in another place. tried again and soon hit the same problem at 10 inch again. After totaly runnig out of swear words, i had a cup of tea and a ponder decided to Geeclamp the tyre opposite the levers to ensure the beads where in the well of the rim as much as possibleand tried again got a bit further this time but found the thickness of two tyre irons stopped the tyre from going on, used one lever only, and finaly got the tyre on and collapsed in a heap. Using my electric pump I put 36 ibs in the tyre but noticed the tyre was not on the rim evenly put 50ilbs in the tyre and still no change.

Did a tour of the garages, Shell, wasted 50p as the the air adapter wont quite fit the tube valve, ditto for Tesco, finally got Sainsburys to fit and put 65ibs in the tire and one side popped out . That was as high a pressure as I was prepared to put in so back home deflated the tyre and sprayed wd40 down between the rim and tyre where the tyre dipped. I noticed that the rim has a step between the well and the rim wall which seems to be for holding the tyre bead in place. back to Sainsburys and up to 70Ibs still no difference!!! back home took the tyre out of the car boot and eureka it had centred its self on the way home . This only took 5hrs to fit one tyre!!!!!
