When I purchased these tires they filled them up to 38 psi. Almost 5K miles later I went in to have them rotated and they fill them up to 50 psi. I asked them why they went with 50 psi and they said they should be ran at that pressure. :wow: What gives? 38 or 50 psi??? What do you think?

What pressure are you running?

Okay I called Nitto and spoke with the tech dept.
He looked up my truck on the computer and said:
Dodge Ram 1500 4X4 stock psi is 35.
With the E load Trail Grapplers LT295/70R18's 45 psi is what you want.
Set them at 45 psi.

I have 295/70/17's do you think mine should be any different then 45?

The dealer I got mine from says to run them at 55-60psi. I put them at 60 for the last month and the ride feels perfect. I will have to call Nitto as well, I don't want to wear these suckers out too fast.

I had mine at 40 felt a little soft and sluggish, put them at 50 and it feels a lot better, was even thinking about trying 55

I dont know about the sensors but if you go to nittotire.com - grappler truck- (type of tire your looking for) - then click specs, there will be a chart with all the info on the tire you need including psi, load capacity, tire diameter, and rim size needed.

On the chart it shows maximum psi and loads. I have a feeling I shouldn't be running 80 psi that just sounds way to high to me.

deffinetly wouldnt run at 80 unless you have 2000 pounds in your box... I would imagine the ride is pretty rough

Alright so we know the maxes. But is anyone running perfect tread with the Nitto Trail Grappler LT295/70R18E (max. 4080lbs @ 80psi) daily city/highway driving in a Ram 1500? Please let me know what pressure you are running at, would love to clear this up. Currently running 50psi daily driving. Had the tires for couple days now. Or im off to do a chalk test.
