People have said the TrXus MT's are fine on the road, except for the people complaining about blowouts that is. They're no bogger.
I've run many sets of BFG's over the years and although I generally like them I was leaning to the TrXus because I wanted to try something new. But if they suck, I'd rather find out now than after I bought a set.
Don't make MTR's in that size AFAIK.
