I don't have a protractor (angle measurer) to take with me, but I know what 45 degrees looks like and half of that... (draws on a piece of paper) ...okay so maybe it was more like 15 degrees.
i only just read all the replies to this thread seeing as ive been away and there seems to be some confusion, i have absolutely no objection to a muddy tire, but the tire in question is my 20" trials job of which i like to keep clean ish, and besides muddy tires dont go down to well for indoor home riding.
im saving up for a Muni neways, which inevitably will always be covered in mud.
