Terra Grappler tire pressure

[pcut]

Yes, I've done several searches and can't find a definitive answer. What pressure should I run for on-road/highway driving in my 275/70/18 Nitto Tera Grapplers? The searches are all over the place from 32- 50 psi. I'm looking for real world experience as opposed to a formulaic/mathmatical calculation. I have an '06 TLC with OME lift, Slee bumpers and swingouts and a Warn winch. Thanks in advance.

What load rating are your tires?

I have 305/60/18 P-metric NTG’s and I run them at 32 psi. I’ve tried 35 psi but I don’t like the decrease in ride quality at that pressure. I drive pretty aggressively at times and 32 psi works fine in that respect as well.

I run about 32 psi on my 285-75-16 tires. Rides great.

38 psi, 305-70-16. Rides great. Of course, Im not into that super cushy oem ride

Load Tables

The tire and rim manufaturer's association actually has a process for working through a swap from p-metric tires to LT tires ... see this post where I gave a link to get more info ....

If you can actually get a weight on each corner, you can simply use the load / inflation tables and be good ....

I run 38-40 on my 285 NTGs. It's a little harsh but I don't mind

I also have the same tire and size, and I run 34 up front and 32 in the rears, comfy but tracks straight.
