I use Contiescape tyres, they are a good universal tyre. I get 8,000k out of the rear & 12,000k out of the front. They are good for most of my riding, hard top & dirt, the front tyre is not so great in the sand a knobby is much better.
desert on the back and a karoo on the front. Im running a full on knobby onthe front at the mo and its all over the shop after 100 kph unless its in the dirt and pushing
Deserts are great all-round off road tyres for the HP (as most other MX tyres are simply not up to a 100+ BHP heavy bike and will tear to bits) but are a bit 'loose' on wet tarmac.
Am on regular Karoos with tubes..... a heavy duty metzeler 21' tube up front and the same HD tube but 18 inches on the rear with 17in wheels. i have a set of Unicross tires too... incase we decide to do a little bit of semi single tracks....
