Well,.,.,.,.,. first thing to realize is that all you funny-talking people in Euroland get Schwalbe tires for cheap compared to us US peeples.... Most bicycle tires in the USA cost $20-$35, but the Schwalbes are up around $50. The importer is in Canada, so we get to pay for shipping twice. Here, Schwalbes are one of the most expensive brands for the 26"/559mm size.
For the price you're paying (£16.99, Fat Frank) they're not bad, but not anything special either. Many US people building antique-style motorized bikes pay for the Fat Franks because they come in cream and brown colors, though I recall the N American distributor couldn't get anything but the black ones for a long time (I don't know if that problem is resolved or not).
For what it's worth, among non-motorized riders the Marathon tires get mentioned a lot more than the Fat Franks.
Also we note: 2.35" wide tires will rub a lot of engine chain-drives unless special measures are taken.
