Duragrapplers at 65,000 miles

[Regcabguy]

We finally sold our place here in Kalifornia, now get to move south of Carson City, NV. , or back to America as I tell everyone.

Today I had a set of Dura Grapplers installed. The stock Michelins were still "legal" with 69745, but it was time to go.

We went through that area recently. Pretty nice. You just got a raise. No more state income tax if I'm correct!

The list is way two long to type, but, no income tax is great. Also in our county here in La La land you cannot hunt with lead ammo, get your items in store in a plastic bag, go on to national forest land with out permit, and on and on. The stupid have completly messed up a former great state. I need to get down of my stool before they come and get me.

Greetings NITTO users;
I too was apparently overloading my Michelins [265/75R17] towing my RV. After much consternation & lack of specs I felt trustworthy, I popped for 5 new Dura Grapplers [285/70R17]. I'm counting on their additional load rating of 555#/tire. Since we tow 10K, not tow 20K miles, I would really like to see a NITTO tire "inflation vs load" chart or table. I've emailed them, but still waiting.

Anyone have it? Thanks for watching.

Weigh your rear axle.

3750/80 = 46.875lbs per psi. This is going to get you close, if not over the minimum air.

But run as much air as you can.

The Nitto technical department said they did not have their own tables but that one could use the Toyo table for the same size tire. The Toyo tables can be found here: http://toyotires.com/tires-101/load-and-inflation-tables

That doesn't correlate at the Nitto and Toyo have different load capacities for their 285/70.

Just passing along what they said:

HI Jim,

Actually, we use the same tables as Toyo. As long as the size matches up, you can use that inflation table. If you see that the center of the tread is wearing away too quickly, then you will have to lower the air pressure to get a more even wear across the tread.

Sorry, we do not have our own table but the Toyo inflation table can be used for your Dura Grappler.

Thank you,
Nitto Technical Department

How much different are the load capacities? Are you splitting hairs again or is there a significant difference?

i'm on my 3rd set of dura grapplers on my06 in the 285 flavor.i carried about 1000lbs in the bed most of the time and ran 65 in the back and when towing 80 up front around 70 seemed right but i also am a spirited driver and used to drive it like a sports car. i got about 40 to 45k out of each set and could have gotten more but a few burn outs and having fun shaming other cars on the road tend to eat tires. the 265s i had on my 2011 didn't fair so well but the rears were always near their max payload and ended up having a major blow out

The ATII's are 3195@80 and the Nitto's are 3750@80.

Thats an interesting formula, I have never seen that but it kinda makes sense. Does in take into consideration the tires speed rating?

It doesn't, it is something I used and saw a lot when I was in the 4wheeling scene.

When you compare the load charts to that formula the formula always (at least from what I have seen) gives you more pressure so I feel it's very safe as a starting point.

 

[MA2LA]

in the end you really need to adjust to what you find is right for your truck and driving habits. I tend to use a higher pressure than what is recommended on most of my vehicles and i keep good even tire wear generally i tried that formula with my 245/19.5s and the steers on the ribbed steers on the front worked better with much higher than you would think pressures for the rated load vs actual but then again the 4x2 independent front suspension on these trucks is not the greatest IMHO they finally got it right now by copying the 4x4 set up .

The ATII's are 3195@80 and the Nitto's are 3750@80.

If you look at the load inflation table in the link (page A1 Open Country AT) you'd see the LT285/70R17E is listed at 3195@65psi and 3750@80psi. Matches the Nitto and appears to be an appropriate table.

Too bad Toyo downgraded the load carrying on the newer ATII's.

I missed that page, that will work well.

Yeah I am not sure why the ATII's are lower, 17" rims get raped on weight ratings.

Based on the chart 2105lbs @35 psi, based on the math 1640lbs @ 35 psi.. so the math has a bigger safety buffer in the absence of a chart.

 

[Regcabguy]

I had premature center wear on my Toyo AT's @ 65 psi with the stock rims.
Due to the camper weight though,I need to keep any tire at 60 psi+.
Wish I could afford some 17 x 8.5 Walkers.

 

[AH64ID]

I was always adjusting my pressure when I ran 285/70's on my OEM rims, it got old.

Whats the sidewalls look like? My Michelin look as good as yours with about the same miles, but have weather checking up the whaaaa zoooo
