My Nitto Dura Grappler mini review, after 40k miles.

Vehicle:
F-350 Crew KR dually diesel weighing 7990 lb. empty (no driver, half tank of fuel). Tires NEVER rotated. (Wearing pretty evenly.)

I finally clocked 40,000 miles on my Dura Grapplers. Tread depth started at .5" and are now at .3" (give or take .025") per tire.

I have towed heavy trailers and loaded the bed with up to 4500 lb of dirt and gravel, as well as 3000 lb of wood and other materials. I'd say about 20% of the life of these tires has been under heavy load, as I don't tow daily.

100% of the tire life has been in mountainous terrain, driving mostly winding roads up to 60 mph (slower on the hairpin turns). Additionally, I've driven under all conditions (snow/ice, rain, dry, dirt, even through a small river occasionally).

They do very well in all conditions, but now that they've worn in, they do slip a bit on ice. In 4WD, no problems at all. I have to admit my limited slip in the rear end is not working, so 2WD is really 1 wheel at this point. (Will be fixed when I service the diff. this month.)

The only tire I have to compare is the stock BFG Rugged Trail, and it was almost a slick at 60,000 miles driving on flat land in Florida. (Hometown is Tampa, FL.)

So far, this tire is performing better than expected, having lost about half of its tread depth in 40,000 miles, and not being rotated at all. At this rate, and driving the same way, I should get 80,000 miles before I get new ones. I highly recommend this tire.

Great write up!!

I really like this tire as well. I don't have a dually, but I do tow a 40ft 5er quite a bit. I only have about 10K on mine, but they are wearing very well too.

Thanks,
Mark

What is the dura grappler compred to the terra grappler? I have the terra grapplers on my new 6.4. Was considering Nittos for my dually later in the future.

More like an aggressive hiway tread.

The largest Nitto makes in the Terra with an "E" rating is a 295. I tow a heavy 5er, so I need an "E" rating, and the Dura comes in a 305/70-18 which is basically a 35" tall and 13" wide tire. They also make a 325/60-18 which is 33x13. I have the 305s.

Here's a close-up of the tread.

Well, I can tell you that we had monsoon-like rains over the winter and early spring here in central Texas and they worked like a champ through it all. Never even close to hydroplaning. If you do some serious towing like I do, they're great!!

And of course, I got them at Discount Tire!!

I've driven through some heavy rains with mine and had no slippage at all, even leaving from red lights going up hill.
