Spools will cause accelerated tire wear with any tire...even if you ran no tires and steel wheels. That's a fact of life. Out of the three, I'd say the BFGs would have the longest life. The Yokos would come a close second. The GYs a close third. Traction wise...in mud, it is pretty close between the BFGs and GYs. The Yokos come in clearly third. Traction elsewhere...snow, wet roads, etc...the GYs come in first, the BFGs a slightly distant second, the Yokos third. Rocks...Haven't observed enough of the three to make an educated statement. I run BFG MTs in 33". They work very well and I'm quite pleased with them. From my observations selling tires, I'd say with confidence that they will last longer than the other two, and would be slightly more durable behind a spool. That said, if I were buying tires right now for my jeep, I'd get a set of 35" swamper SXs, so I'd have an excuse to swap out my front D30. But from the choices you gave, and if it were my daily driver, I'd get the Goodyear MT/Rs. DO NOT GET CONFUSED AND GET THE OLD GOODYEAR MTs. They blow (no offense intended to their proponents). The durability difference is not enough to offset their superior traction, IMHO--Not that the BFG isn't a quality tire. You will note that I am leaving the Yoko out of the picture altogether. I wouldn't even consider it. Yokohama has excellent quality control, and the tires are produced wonderfully, and look quite aggressive, but traction wise, they just aren't quite there. They work quite well in deep snow off-road, and I've read that they work pretty decent in sand (haven't seen that myself, again), but having sold and seen a few sets, I wouldn't get them myself.
My $.02 FWIW
I Jeep, therefore I am.
