Hello ! Itoday I swapped my 2010 boardman fs comps continental speedkings for a new pair of schwable Racing Ralphs .... unfortunatley during the second half of follow the dog .. the tyre came off the rim .... then again and again in half a mile stretch..

I've 18mm Ritchey OCR rims ive my first race next week .. so not really sure what to do ..

Talk to the place you bought them from.

They may be faulty.

Maybe you were just getting so rad that you blew the bead off the rim, i've done that a few times

I bought some non tubeless Swalbe Nobby Nics last year, they were baggy and slack on the rim, There was no way they would ever run tubeless and without a really good lip on the rim, they wouldn't go on very well at all... Sold them to a mate and it became his problem :0)

While we're on this subject does type pressure make a difference? ie:- low pressures make it more likely to occur, or pressure has nothing to do with it?

Hell yes, too high and it can blow the tyre off, too low and it can roll off.

I had a Boardman, with 18mm Ritchey OCR rims, and 2.25" Racing Ralphs, they were fine. Sketchy in the wet (!) but fine in terms of staying on the wheels.
