UST rims with tubed tyres

Dear All,

I have recently bought myself some mavic crossland wheels for my daily
commute to work. Last night I sat down, for what I thought would be a
ten minute job, to swap my tyres onto the new wheels. After a good hour
(maybe 2) of trying numerous methods of getting the tyre to sit in the
beading I finally succeeded. The tyre would pop into the beading on one
side but not all the way around on the other. Therefore giving a
lopsided (sp?) tyre in a couple of places on the rim.

Unfortunately for most of the punctures that I have I do not have the
luxury of sitting in my living room to mend them. I am usually by the
side of the road, in the dark and using a mini-pump.

In the event of having a puncture how important is it that the tyre sits
in the beading? I realise that it will not do much for the handling
but will a slow ride home (say 10 miles) damage the tyre or rim? If
this is not a good idea then what other options are there? Is it just
technique? I can hardly carry a bowl of soapy water around!

Thanks,

Gordon

Some rim tyre combinations are very, very tight.

Solution. Fit the tyre *without an inner tube* and using tyre levers
several times (e.g. 10) to loosen it up.

Some combinations do seem extremely difficult to seat properly. A while
back I saw a suggestion, possibly in URC, that gently riding 50 yards
or so on the tyre before inflating it seems to get it seated. It sounds
extreme but I've tried it once or twice, more out of curiosity than
anything, and it has worked. It's not without risk of course, but as
long as the tyre stays on the rim there should not be any significant
damage over that kind of distance. Of course you should double check
that the tube is not pinched and that the valve is still straight
before finally pumping it up.

Seconded (or just mount it and leave it for a week, which sometimes
works the same). Use lots of talc on the tube, as it helps it slide
over the rim when things get tight, yet still allows your (by now
bleeding) thumbs to grip the tyre - unlike washing-up liquid.
