Im having problems with the rear tyre on my 2010 300 4stroke the rim seems to be very slightly to small as we cant get the tyre to seat properly when we put it on even when using a comressor to blow tyre it up , you can even get a new tyre onto the rim without using tyre levers and when you blow it up it doesnt POP onto rim its more like a wet fart ? So needless to say as soon as i try to use it the tyre leaks ive even had to fit an inner tube but twice the tyre has moved round on the rim ripping the valve off the inner tube ive tried 2 different makes of tyre and still having same problem . Anybody out their had similar issues ? Thanks in advance

check the welds where the rim has been joined, some 2010's were badly welded then smoothed, and caused poor seating of the tyre. that said in my case this caused more of a rim tape issue (whole other problem). if its very poorly welded perhaps lampkins can help you with a new rim like they did me? worth calling them.

Cheers twinkletoes will take tyre off tomorrow and check , local trials shop can't see anything obvious when they have tried another tyre may have to have a word with Acklams where I bought it it's still under warranty just trying to save a 2.5 hour round trip it's strange how the tyre isn't a tight fit ??

Is it a Michelin or Dunlop tyre?

Michys always have been a slack fit!

Tried both a michy and IRC , it came as standard with a michy but I prefere IRC so swapped them and that's when the problems started so thought the IRC was a slack fit so put the original michy back on ( only been used 3 times ) and still no joy
