After 47k miles, my terra grapplers are down to a little less then 3/8" of tread. I have been very happy with the terra grapplers, however I am wanting something different this go around. We have our share of snow here in Indiana and I occcasionally venture off road. I probably tow 3k miles a year. I will probably go with a 275x70x18. Can anyone provide any feedback on the two tires listed in the title?
