I agree with Mollydog that the Conti TCK80 option is probably best for your requirement. I use Michelin SIRAC's on my XT6E but I guess these are too road orientated for you? The TCK's are mid-way between onroad and offroad tyres whereas most others (like my SIRAC's) are one or tuther. I think my Sirac's are very good allrounders but they really are 75% road 25% (mild)offroad tyres. The TCK's are nearer 50% road, 50% offroad.
