Tire Pressure

I prefer 105 for steers. Better ride. 100- 105 for drives. Trailer, 110. I’ll run them all up a little higher, in the fall. Always lose a little when it turns cold.

 

Yea 120 on steers is nuts. I run 100 psi front and drives/ 110 on the wagon.

 

Ask the guys in the WE shop.

 

I’ll be the odd man out..I go by what is recommended on my tractors door jamb tag.

Kenworth T-680
105 psi steers.
90 psi drives.

So far it’s working for me. I check and adjust the pressure often and only when they are cold.. One thing that I don’t let the TA touch when I get a PM.
I’ve had perfect tire wear so far doing it this way..along with new shocks every 125-150k

 

Being as this is not your truck I would recommend asking WE what they want their tires to be run at. Might not necessarily be the optimal number that they give you but it is their truck so should be done to their specifications so long as it is safe.

 

Exactly. You don't need the hassle of being called to the mat because you didn't follow company policy. And get it in writing.

 

You can pay a little extra for helium, it won’t be advertised but ask the maintenance guy about it. He’ll hook you up!

 

I run nitrogen in my personal vehicle, would helium increase my mpg and flight time at railroad crossings?
