I put some Nitto Terra Grapplers on my truck at the end of the summer last year, and I thought I would give a little review of them to share my thoughts about them. The size I got is the 285/55R20 load range E tire. I currently have a little over 20k miles on the tires, and they are wearing very well. I just measured the tread depth, and they are all right at 10/32 of tread depth and wearing very evenly. Nitto lists the tread depth of this tire as 15.6/32 when new. That puts the wear at about 65%. Neither of the two previous sets of 20" tires I had made it past 25k miles (Cooper Zeon and Nitto 420S, both in 305/50), but these are on track to make it to 40k or more. They are a smooth running and quiet tire but a little harsher on bumps than previous tires, most likely due to the higher load rating. I haven't run into any problems with them in any conditions (even drove in a little snow/sleet mix stuff during the winter). So far, I'd have to say I will be buying these again, and I will recommend them to anyone else.
