Just put a set on my 06 f350. 275/70s. If anyone else is running these. What pressure are you running?

 

I have run a couple sets now on my F350 DRW. Really like the bad weather performance. pressure depends on need for me. bad bad weather no hauling 15-20psi in rear and 45-55 in fronts. (600lb in bed) Otherwise factory specs do well. 65 in front and 35 rear or 45 for 70mph. Have run higher and lower hauling heavy. I like 70-75 in fronts and 45-50 in rears.

 

OOPs, different size and DRW. Sorry.

 

Yeah I'm a single wheel and 275/70/18. Tanks though

 

Sorry double post.

 

Using LT265/75/R16's on mine and run 70 in the front and 75 on the rear. Of course...I am pulling my 5th wheel a lot. Like these tires though!

 

Depends on your weights if they are not stock tires !!! suggest you do a google search for the chalk test...

My truck's placard calls for 65 F and 80 rear --- no WAY I'm riding around in that buckboard at that psi...
based on my cat scaled weights, I can go down to 55 psi and still handle the unloaded load properly.

Swapped trucks with my stepson this week and driving his raptor -
it currently has cooper discoverer a/t3 315/70 r17's on it,
not the original tires but they are the stock size--- HUGE tires... and the placard calls for 44 psi... the tpms likes that psi and it rides fine.

BUT, a word of caution rotate those puppies religiously, and often...
he skipped a tire rotation (or two or six!) and they are badly cupped with miles and miles of tread left....

the ford owner site had NO maintenance listed for it... so while I got it legal for me to drive -
replaced the turn signals that were out, got it inspected, got a slow leak fixed in one tire, and stuck the new tags in the window that are shown laying on the dash....

I refuse to get the tires shaved or any of the maintenance done that should have been done over the LIFE of the 58000 miles

He owns three or four companies - he can do all that

 

Chalk test never thought of that but I will try this

 

I run my Cooper AT3s (LT275/70R18) at 75 PSI unloaded and loaded with no problems. Rotation is always at 5000 miles ±250 miles (Pretty much at any oil change interval.) As for the ride quality, it's a truck!
