Bit subjective, will be difficult to find a tyre that works on everything too and is still quick. Conti 2.2″ Rubber Queen in Black Chilli Flavour is about the best all round tyre going currently (if you’re not racing) IMO, but whilst it’s not the slowest tyre in the world, it’s not the quickest either, and is better suited to front use.
I get on really well with the 2.25″ 60a Maxxis Crossmark on the back. Light, fast and grippy in everything except deep mud, but even then it’s nicely predictable. Schwalbe Racing Ralph’s are pretty similar if a bit more fragile and don’t last as long.
But there are hundreds of tyres out there, and everyone will have their own opinions. Just buy one, and if you don’t like it, sling it on the classifieds on here and buy a different one… I’ve come to the conclusion that personal trial and error is the only way with tyres.
