Yes off road is ok. Not with thunder burt's but I had Big Ben's measuring approximately 53mm and mud was an issue. But the TB's on my rims measure ~47mm so more clearance. If your planning on riding through a lot of mud perhaps ditch the fenders. Though I've seen fender-less rigs brought down by mud.
Also I could see where riding through a lot of debris might be a problem, with sticks getting caught between tire & fender. I've had it happen on my Hilsen & fenders with much tighter clearance. When it happened the SKS fenders have a break-away safety front fender. Clear the obstruction and re-seat the fender stays and yer rolling. Hope this helps.
