Tire pressure

I got my km2's and wheel combo the other day. All 5 tires were inflated to about 42 PSI that seemed like way to much so I dropped them all down to around 30.5 PSI was that a wise decision on my part? I'm going on a long trip soon and I don't have time to draw a line with chalk to find the perfect pressure but am I in the ball park for 32x11.5x15 KM2's or should they be up around 40 like they came?

I don't have any idea what you're driving, but I run my Hankook 33s at 28psi

If you're going on a long HIWAY trip, you probably should sacrifice some comfort and run these KM2s at 32/34-psi

You'll make it a LITTLE easier on the race engine and help your mileage-, but

Any time I was staying at home (with your '06), I'd drop them to 26/28-

You might get some posts from some OTHER 06 TJ owners, but

Mine JKs a lot heavier/bigger and 28psi works for me-

Happy Thanksgiving !

With that 4 banger, air is going to be your friend on the hiway. (Not in comfort, but power & fuel economy)

Another simple test is to wet your tires down real good & drive them onto smooth dry concrete. The tracks should be uniform all the way across the tread.

I run 24 psi in my Toyo mud terrains on road, 10 psi off, 8 psi in sand.
