Got a pioneer 1000 that has about 6k miles on it and its getting close to needing new tires. The bighorns 2.0s on it traction wise are great but they are not durable enough for me. Every tire has multiple plugs in it and it seems to almost be cracking at base of lugs, maybe rubber degrading? My ideal tire runs lots of dirt roads but must be able to handle deeper snow well and sharp rocks at times, thinking 8 ply... Any recommendations or tires to stay away from
