I was converted by several notable members of these Forums to buy and install Schwalbe Smart Sam (standard issue) tyres on my Vado (47-622, 28 x 1.75"). It is impressive how quiet and fast rolling these tyres are on road, while I can ride them (with some effort) through the sand off-road. Smart Sams feel very sporty and dampen the road vibration very well even close to their maximum inflation pressure.
Some Forum member distrusted my word. Listen to Smart Sam compared to otherwise excellent but off-road only Maxxis Rekon. (It is hard to stand the trail-tyre noise on road for extended ride duration).
