Still dont have my MTZs on the road to give a report. Good looking tire. Decent amount of siping, which was important to me for traction in slick (wet, icy, etc) environments. The GY MTRs will break loose on you on wet streets...other than that I loved the set that I had for ~3-4K miles. As far as the MTZs, I dont know about spendy...if you want the 14.5" wide versions, yeah, they are steep as are ALL 14.5" wide MTs. I got my 35 X 12.5 15s for $125 each to my door at the last 4WD Jamboree...but MT was giving a $25/tire instant rebate and they (4WP) were dealing that day....I also got a MM SI9500 for $450. I think the MTZs can be had for $170-175 even through Summit for the 35"s. Good luck.
