The other reason for a good thick layer is when pulling a tub off so much glue is left behind that the preglued spare get a good strong bond instantly. Downside on my hed rims i have to carry a tyre lever to ease the tub off. Even more diffiult getting my mtb tubs which i ride all the time of my 27mm wode carbon rims. Fortunatley the geax saguaro's are very robust tyres.
