I would like some help on what psi I should start out with.
the tires are 35x12.50x17 BFG/MTs thanks.

 

I put 33's on this week and started with 40psi. They ride well but I feel more of the road than I did with the 29" Goodyear Wranglers that came with the Jeep. I might drop it down to 35psi to see if it's any softer.

 

the tire shop had them at 50 so I went down to 35, some body told me to go down to 30 but that mybe to low

 

I'm running 30psi in my 35's, mainly because I used to run 25psi in the 38's on my CJ and since the Jk weighs more, hence the increase. Seems to be a good psi and wearing even, but I haven't used the chalk line check yet.

 

I run 32 psi on my procomp extreme mt's same size

 

SOo 30 is'nt to low for everyday driving?

 

What's the chalk line check?

 

Works well for me.

You take a piece of chalk and draw a line across the tire, from sidewall to sidewall, drive it straight for 30-50 feet and check the line. If there is chalk on the outside near the sidewalls only, then it's over inflated, on the inside only, under inflated, pretty much gone, it's just right.

 

Somewhere around 30 psi is going to be about right with 35's on stock size rims.

 

I am running my nittos at 32
