Hey guys. I have a 2011 sport with a teraflex bb and 285/70/17 Falken Rocky Mountains. I did a chalk test today and all tread was making contact at 26psi. Does that seem too low? I don't have any weight on my jeep. I was just curious if anyone is running their tires that low. Thanks

 

I'm running ~27psi in my~36", I'm happy so far.

 

But you have 36" tires. Does it really matter that I have 33's and running them at 26? Does it makes sense that I can run my tires at lower pressure since I have not extra weight on my Jeep?

 

What load range are they?

 

I run the Cooper Discoverer STT in 285/70-17. I also done the chalk test, and I run 25 psi in them. I rotate all five tires every 5000 miles and ckeck them with a depth gague when rotated and they are wearing perfectly.

 

Yes, I think that you should be fine, & agree that less weight may work to your advantage. You can also change your psi if you don't like the feel, it's too spungie add some air, etc.
^This? If you sidewalls are very thin/thick may effect how much psi you need.

 

Ryan0260 the load range is D. Thanks guys for all the info! 26 psi feels good and leaves a even wear so I'm just going to leave it at that. I just wanted to get some feedback. Much appreciated!

 

Run my E load range at 28

 

How can I see what load range my tires are? I'm running nitto trail grapplers 265/75r16 and I'm running 50psi and that seems way to hi now

 

Wow, that's way too high. Get them down to 35 psi to start. When you have time search chalk test.
