OK so i just got my 34.6 inch tires(Goodyear wrangler duratracs) in(315/70R17) I am mounting and balancing them on my stock 17inch steel rims.They have some type of limiting rim slip on them.

Question is should i get new valve stems?Should i get just regular high pressure ones that just go in,or some ones that screw in?

Other question.With putting them on my stock rims,would psi need to change from 44 to higher?

For those who want to say you can't mount and balance that size tire on stock 17inch rims,don't want to hear it cause i know you can.Thanks for all your help guys

 

Bump to my own.Anybody?

 

I'd do the chalk line test to find out the best PSI.

 

Whats the chalk line man?

 

Rub some chalk across the tread then roll the truck. It will leave lines of chalk on the ground showing you what part of the tread is contacting the asphalt. When it's overinflated the outside edges won't mark, when your underinflated the middle won't mark.

 

I would go with the screw in type I've seen the push in type tear out with off road use.
