I have a 2016 15 passenger XLT wagon and just put on BFG KO2 225/75/16's. Love the tires but my mechanic set the pressure in the front to 60psi and the rears to 75psi. The ride feels a bit rough and maybe im just not used to the AT tires and am wondering what others have theirs set to? I wanted more capable off road tires as I live in Vermont and needed a better tire for winter driving and for traveling on dirt roads while camping and fishing. I weighed my van this morning and with the 4th and 5th row of seats removed it weighs 6460lbs. Ill be adding a raised bed to the back with a bedslide underneath, this should not add more than 300 pounds to the total. Add a few kids/wife/gear and bikes and we will be around 7500lbs at most.
Thanks for any help,
Steven

Doing some math for 7500lbs I'd figure around 56psi all around for the max load of this tire, and therefore I'd do 60psi~ all around and adjust accordingly based on wear and feel. Even for the unloaded 6460lbs, I'd still probably retain the 60psi front and rear unless you want to mess around with the TPMS.

Thanks Andre, I changed all tires to 60psi and the ride seems much smoother. The back end stopped jumping around on the washboard dirt roads.

Awesome to hear, I have my wagon at 60psi all around on the stock tires. It feels good and thus far the wear is pretty even.

AFAIK, tire pressure is to large extent, a function of sidewall stiffness and contact patch area. Given that the BFG's have a larger contact patch and a stiffer sidewall, the optimal tire pressure for these should be lower than stock by a factor of the two contact patch areas.

I have found the same to be true when putting wider wheels on a track car but I use a tire pyrometer to set the pressure on my track cars.

I have that tire, but the 255 size.

I run stock pressure. 49 front and 71 rear.

It is a nice pressure with the weight I run.

How are you liking this tire? DO you have a lift or any other modified suspension? Do you have any issues with rubbing, Turning radius, Road noise , Gas mileage etc? How did you choose this particular size?

Thanks
Michael

I run the same size in a E-rated Discoverer AT/3 with no lift. It’s the closest size to stock available in an AT tire. No rubbing. A bit noisier but not obnoxious. MPG took a minor hit. Handling is definitely sloppier; slower turn in and more movement in high wind. I run stock pressure. Snow and off-road traction is excellent.

In an ideal situation, you would have the vehicle configured the way you will be using it, fully loaded. Weigh the vehicle to get a weight on each wheel separately and adjust the air pressure for each wheel using the tire manufacturers load/pressure chart. The goal is to achieve the optimal tire contact patch on the road surface and that requires adjusting the shape of the tire using air pressure as a function of the load on that wheel. Depending on how the vehicle load is distributed, it is conceivable that each tire would run a different pressure. Hardly anybody ever does this level of fine tuning though.
