Nitto Dura Grappler 285/75/17

Has anyone had Death Wobble issues with this tire?

I hope not! I just put them on my truck. So far, I like them a lot. I like the fact that I now run 1950 RPM @ 65 MPH. Used to be 2150 RPM @ 65 MPH, with the stock 265/70/17 Michelin's.

Keep us updated

Let us know how they work out: wear, grip, etc.

I'm looking to make the same change when my second set of stock tires are replaced this fall.

I've got about 2000 miles on mine... They seem to be doing just fine so far. I will say that they are heavier than what I had on there (245/75/17).

On my second set of them. I guess buying them again says what I think about the first set! Good smooth tire, long wearing and I never rebalanced the over 50k miles they went.

Update

I purchased a set of DURAs (285/75/17) and replaced the BFG TKOs (285/70/17) that were worn. I experienced death wobble for the first time with the TKOs. I immediately felt the difference with the DURAs. They are a much heavier tire and have a much harder sidewall. They are also one inch taller which translates to a one to two mile/hour difference on the speedo. I felt more vibration comming through the suspension. They are more quiet than the TKOs; however, the ride is a little harsher than my old TKOs. It also takes a little longer to get up to speed from a stop.

I went back to Tire Kingdom and paid $132 restocking fee and replaced the 75s with DURAs in size 70 (285/70/17) . Wow! what a difference. These tires are about one inch shorter. They are alot smoother than the 75s and I don't feel any vibration or suspension feedback. At 75 miles per hour these are even more quiet than the DURA 75s. The weight carrying capacity is about 200lbs less per tire.

So in summary: Although they are both DURAs the 70s are very different from the 75s. The 75s are a much heavier duty tire and are not as comfortable as the 70s. If you use your truck as a daily driver with an occasional tow (like me), I would recommend the 70s. If you're going to carry a-lot of weight over the back axle I would recommend the 75s. However, keep in mind that if you have to pull any kind of grade with a load, the 75s are going to use up some of your torque.

I hope this will save someone from having to pay a restocking fee

What pressure were you running in the 75's, for the short time you had them? I went from the stock 265/70/17 Michelins with the Dura 75's recently and have found just the opposite to be true. I find my ride to be smoother, with the new tire. You are probably right about the loss of torque, when towing. I haven't had any death wobble issues either. I'm running 63 pounds up front and 60 in the rear. So far I'm loving them.

I was running 55 up front and 45 in the rear. I later increased to 60 up front but didn't notice any difference. The 75s are a smooth tire, but they feel harder. They will soak up small imperfections, but pot holes will send you to the dentist. Since they are taller they transfer more leverage to the front suspension which gave me an uneasy feeling when I would hit any type of road imperfection at speed (especially over 70 mph). The side walls are much harder and it felt as though the steering damper was not strong enough to get me out of trouble. Hope this makes sense.

Yes, it makes sense. When they installed mine, they put about 45 pounds all the way around. I drove about 70 miles home, with that pressure. It felt terrible, kind of mushy. Next morning, I adjusted to 65 all the way around. That felt a little bouncy, kind of like skipping over bumps in the road. Also, once they built pressure from heat, the outer edges of the tread, were not in contact with the garage floor. I just played with the pressures until I arrived at the 63 frt. and 60 rear. Time will tell though. I think tire pressure is very critical to the ride of the truck. A couple of pounds seems to change the ride quality a lot.

Running 285/70's on mine now and have 25k miles and they still look almost new. 12/32nds tread left on all 4 and wearing very even. I will buy another set for sure but will upgrade to the 285/75's this time. Absolutely love these tires!!

Don't forget that the mold release takes a few hundred miles to completely wear off. The 285/70 and 285/75 dura grapplers are heavily constructed tires made for very heavy loads. A good set of aftermarket shocks will help control the weight of the tires. Unloaded, I run 70psi front and 65psi rear. Loaded, I run 80psi all around.
