Try a few is my advice..

20psi, 22psi and 24psi would be a good spread. see what suits you and how the car responds. Anything above 25psi makes my AT's too stiff and it bounces off speed bumps and potholes.

If you take the time to try a few different pressures, you will find a sweet spot where you are happiest.

Good advice from Sniper.

I varied mine a bit to find what worked best for me. I run Hankook Dynapro ATM 195/80 R15 and find 22 psi front 24 psi rear gives a nice ride. Anything higher and it feels skittish and bouncy.

I have just swapped the tyres between my 2 and when measuring the tread depth found that the 26 psi I had been running in the back was taking the centre out of the tyres. I'm now at 23 psi front and back and the ride is much improved. I have no back seats and only rarely have a full load for any length of time, mostly running empty.

205 70 15 96 h. The size is less important than the load rating which is a code expressed by the 4th number in the sequence I just posted. The higher the load number the less pressure you need for the optimum performance of the tyre. An all terrain will probably be something like a 100 or 102 and will need less pressure than my road pattern. But it also depends on the weight of the specific vehicle, Ermintrude is relatively light weight and needs less air than one with winches or timber storage decks in the back etc.

Then as suggested start with 22 or 23 and go from there. You're wanting it to feel smooth but not floaty. If they're too soft it will squirm an wobble over bumps and holes if they're too hard it will crash and bounce. You're wanting the happy medium.
