Can anyone recomend me some cheap (<£20) MTB tyres – something light and fast rolling for all-day XC enduros.

If your riding all-day enduro's the last thing i would be skimping on is tyres.

62a 2.1 Exception High Rollers are sub 500g, roll well enough and seem tough to be relied upon for all day rides. They are about £25 so not massively over budget. They are small for their 2.1 size.

Cheap is not usually compatible with light!

If its not particularly rocky then I prefer Nobby Nic 2.1's, but for rocky stuff then I go UST Racing Ralph's – heavier, fast rolling and tough.

Obviously neither for £20…
