(at the risk of getting flamed)
One word for off road tire... "Coopers".
Years ago I ran a full sized SUV across remote South Australia for work. And I mean proper desert. Sealed roads out there are very rare. Think big rocks and gravel, mud, ruts for miles, whatever. In more than 8 years on the road I never had one issue related to tires.
