How to inflate all tires with same psi

how do you guys get your tires evenly inflated. My stock sport wheels 265/65r17 are currently as follows cold on the TPMS.

29 30
30 31

All the tire gauge and inflators in nearby retails stores are rated for +/- 1.5-3psi

Would Prolonged driving at these pressure contribute to diff wear.

 

Youre good bro. You can have a couple of psi change just with heat expansion and altitude change. Just get a decent guage and keep them within a #or 2 of each other.

 

I usually pump them up with a compressor and then drop them down with a hand gauge.

If you want the most even wear, Google tire chalk test, and rotate them every oil change.

 

Alright cool thanks guys. And the thanks @Flytmech for the suggestion. I also used two different retail store gauges and got no more than one psi difference on both and the TPMS. I just have an issue with other thinking everything on this truck.
