What tire pressure are you running with your 35s AT tires on your JK for daily driving?
33-35 PSI are a bit hard, 30 PSI feels more comfortable.

If you run 30 it might be smoother but the wear on the tire can increase, as well as fuel consumption. I keep mine at 35 psi.

Agreed. You could do same damage if you run a high pressure say 38 - 40.
I have 265 70 17 and run 35/36 psi all the time and Tyre's last a good 50k km and I'm in sand almost every weekend.

Focus on the future, that's where your life is going. Focus on the past and you will go nowhere.

For optimum on road pressure do the "chalk test" - loads of youtube guidance available.
However in this climate whatever you set out at changes with the temperature through the day and use so its only a starting point.
I've had a box of chalk in my car for 13 months and still not done it yet despite good intentions and know it makes sense. I inflate 33" tyres to 36 psi at the end of a run. They are down at 33 to 34 next morning. Can see 38 + during the day and usually at this when deflating for the next run. My JKU is also my daily drive.
Conclusion - IMHO there is no magic number, play around and see what works for you

Re: Tire Pressure on JKs - 35s AT
thanks for your feedback, I put them back to 35 PSI, cornering & highway drive is better now but the ride is too harsh over bumps.
anyway, its a jeep & it shouldn't be comfortable
