I get my tires filled with 78% nitrogen for free :^)

 

You probably get some oxygen too.

 

PV=nRT

there will be pressure change with temp change, using either gas. I'm working on just how much, but I it is mostly just marketing BS.

 

NASA has been using it and all your major air lines use it too.

 

This may not be an appropriate post for this read, but I'm new to this so forgive me... has anyone ever seem this with the Terra Grapplers? I have them on my 07 5.9 Cummins.

 

I have them in 285/75-16 LRE. Rotated every 5,000 miles they should yield the same mileage as the Bridgestone Revo 2's and Michelin LTX I've had in the past. I like the fact they are all terrain instead of all season. My road gets mucky when it rains/snows, making 4WD and limited slip a necessity.

Bought at Discount Tire with a matching Walmart price, and I would buy them again.

 

I'm using the Toyo AT'2s primarily because of the 3-ply sidewall and extra carcass wrap.
A bit noisier but a stronger tire.
I've never heard of a flaw like that with the Toyo AT2's.
