Just changed from Goodyear wranglers 255/70/16 to BFG All terrains 265/75/16. Have about 35# in each tire and feeling like I am riding a basketball. What type of pressure are others running.

 

I have LT285/75R16's on stock rims on my 98. I run 40 - 45 psi without any problems. But my truck rides really rough now with the BFG AT KO's. They surely give a rougher ride than my old set of Michelin LTX A/T's but the grip in the snow is worth the ride. The reason for the change is the 3 ply sidewall in the AT's, that are causing your basketball ride.

Hope this helps

 

What I did, due to the fact that I changed tire size, was to spray down the driveway with a hose & then drive through it. Look what type of a foot print your tire leaves. Radial tires normally have a slight bulge at the bottom & all of the tread should be touching equally. Keep in mind that this will change with the amount of weight you are carrying.

I have BFG All Terrain 265/75 16's on my truck & have figured that the proper pressure is about 20 psi rear & 30 psi front. I haven't noticed any under or overinflation wearing on these tires. My last set, Pirelli Scorpion A/T's went 40k+ miles prior to replacement with only 20 psi in the rear tires.

 

Remember the front is heavier when empty ..... Try adjusting the front to 40 and the rear 5-10 psi less than the front. Put the tire pressure only where you need it.

 

I agree with sag...

 

I don't...if were talking passenger tires. The higher pressures are for LT tires.

 

BFG ATs in that size are LTs, which as you say make all the difference.

What load range tires do you have D or E. That size comes in either. IF LR D, I would start about 42-44lbs all the way around. If LR E I would start at 50lbs all the way around.

Yes the rear is lighter, but when accelerating, traveling uphill, etc weight shifts to the rear.

 

I have a 2000 supercab F150 4X4 with a 5.4L. I have BFG TA KO's size 265/75/16. I have had these tires before on my 1996 F150 and loved them. OK, onto the tire pressure thing... I usually ran 42 psi in all tires until I tried a little test that I recently read about. I chalked a section of the tire tread on all four tires with bright yellow chalk & drove around a little to see what areas of chalk wore off. This showed me where my tires were AND were not contacting the pavement. I noticed that the chalk all wore off in the front (GREAT!) but the rear showed chalk still remained on the outer edges of both rear tires.
This would most likely mean that the rear tires are overinflated. I am going to try to remove 3-5 psi in the rear since it is lighter and see if the chalk remains on a second test. I will let you know the results...
