Need new tires on my truck. I pull a trailer most of the week with about 2000#. Want to go with either BFG A/T or M/T's. Size will be 33 x 12.50 x 15 on 15 x 8 OEM cast aluminum wheels. I've gone thru a couple sets of inferior mud tread tires from Wal-Mart, (super sports), that lasted 8K miles.(Crap). I off road app. 10 % of the time. I want to put BFG A/T's or M/T's on next. I know that the A/T's make more sense/ I drive most of the time on hard track and pulling a trailer. But I like the look of the M/T tread plus the 4 wheelin I do. Could I expect 15 or 20K mileage with the M/T's, pulling my trailer most of the time? Or should I opt for the A/t's? I have an 87' K5 Blazer Silverado 350 EFI /3.73 r.a.,/4 spd auto/H.D. rad & trans/tow pkg. Comments appreciated.
