You have picked well. I and many others have put many miles on both of them.
Best case with the BFG's was 60 k+ on a Tahoe. 16" 35's. Yea, I wore them all the way down.
Best case with the MTZ's was 40 k+ on an F-250. 16" 38.5's. Sold them with over half of their tread.
Off road the MTZ's edged out the BFG's. MTZ' were phenomenal in the mud. BFG's were stellar performers in the sand.
Both were pretty quiet on the road for a mud tire. But the BFG's were quiter.
Both handled great on the road but the BFG's are really good at not hydro planing, not that the MTZ's were bad at it just the BFG's would not seem to hydro plane at all.....
I really like the knarly look and side biters on the MTZ's. Since the BFG's and MTZ's are so similar in performance the MTZ's would be my choice Bro.
