psi for 285 BFG ATs

What are you folks running for air pressure in 285 BFG All-Terrains (Load-Range D) for road driving?

We run 60 psi on our 265's, but don't follow that example cus it makes for a bad back. The tires don't absorb any bumps.

Re: psi for 285 BFG ATs

Depending on the weight of your truck, people in it, gear, etc. I have found that 40 to 50 works good. I have smaller tires but an "E" rating and I run 43 front and 40 rear. 3psi isn't a big deal, but I've tried the water thing, chalk thing, and felt the ride at many pressures and I like this best.

<font face="Comic Sans MS"> Do the chalk line test. If you're not sure what this is, just do a search of this forum for chalk and set the date range to all.

Re: psi for 285 BFG ATs

I run mine at 45 psi and they have worn very well considering i havent had it aligned in over a year and rotated in about 2. Have had them about 3 years now.

How does it feel to be beaten by a sewing machine?

dad's running 50 psi in his 285s on his 2500 diesel. the tread is NOT even...there's about .75" on the ouside of the tire that does not touch the ground. he's runnning higher psi cause he's towing the 36' combine header.
