Can I add a PS to my previous remarks re the use of WD40, please? As my bike has tubed tyres I hadn't thought of it being used for removing tubeless tyres and was therefore only thinking of possible problems with its effect on tubes. I've no gripe with using it on tubeless.

When I do change tyres/tubes I first of all use soapy water and then take it to the local garage's airline in the car to seat the tyre in the rim. It NEVER seats properly, one side or the other never centralizes (with the raised guide line running parallel with the edge of the wheel) so every sodding time I have to let all the air out and put the garage's tyre lubricant goo on before trying again and again. Yes, the rim is clean and without nasty patches of corrosion.

Am I alone in having this grief every time?

Incidentally, I always use the standard BMW toolkit tyre levers, they're about six or seven inches long (150/175mm)and find them perfectly adequate once I've broken the seal between tyre and wheel. For that I just follow the suggestion in the rider's handbook and use the centre stand to press the tyre away from the wheel. The thing is with that, though, is that by tilting the bike I often end up breaking off the little extension on the left hand side of the centre stand, the one you use to push the stand down initially with your foot before you put the bike on its stand. Does anyone else have this problem, is it me?

Cheers
