comeragh and Pleiades, thanks for the comments. With all the help I will try the advice and sure I will get it. The tyre is a Anakee 3 and incidentally it is the tubeless wheel I got converted but I don,t feel that has a bearing but I might be missing something. Bart fills in the well of the rim so I thought the tyre might be hard to get on but with lots of lube it went okay. It has seated on 95% of the rim and with your tips I will get it seated sooner or later.
