Ah finally someone who gets what I'm doing! Yeah it's a 24x3.0 Duro tyre which is really 2.8 and not as big as the old 24x3.0 Nokian gazzaloddi (which unfortunately is no longer made). Still it's cheap compared to the front 26" tyres I run! Might go for a 26x3.0 tyre on the front next summer...hehe
