Yes the BFG's are really expensive now. It also grips me a bit, paying that much for a design that hasn't changed for so many years, I fitted a set to my Wife's old 300Tdi Disco must be about 18 years ago, and they are still identical. I also had a really bad experience with the old BFG MT's on my old Ninety.
I do like the look of the Wildpeaks, closest size I can find to what I want is 275/55/r20, they don't seem to do any 285's, I'll have to look at the actual dimensions a bit closer. The Geolander's I'm not so keen.
