I have been seeing more and more people running 35” tires with the stock 18” fx4 rims and was wondering what the proper tire pressure should be to get the most out of your tires

Thanks in advance for the replies

 

I have been running 45 psi for about a year now and they are still almost like new

 

Putting mine one this weekend 2" autospring 2" add-a-leaf and 35" bfg ta ko's. Was thinking mt’s but didn’t know if they would last. Sounds to me like yours are lasting quite well. You do a lot of pavement driving
How is your rubbing situation on the control arms and the sway bar?

 

Depends upon the load range of the tires and max psi on them. Each load range would be different. What is the load range of the tires (p series or LT LR ?) and what is the max psi on the sidewall?

 

my 35 12.5R18's are E i run them at 45 in the summer, and 36 in the winter

 

Sorry to change up the thread a little. Now that a couple of you have been running it for a few months or years, what is the verdict?

How much rubbing is their really and where do your tires rub?
Is it worth is or did you end up going with a lift kit?
And any other comments you may want to add


Thanks

 

I have no regrets on what I did, I have a little rub at full lock to the right but it’s not that bad. They touch the upper control arm. I would not change a thing on my truck, I love this setup.

 

That is one nice looking truck AKFX42004. Good to here that the 35's are doing well on stock FX4 rims. Not many can afford to buy a set of rims as nice as those and a set of 35's.

 

Ive been running 36psi all the way around. Im thinking about bumping it up to about 42 and see it helps my shaking.

 

Go to the max psi on sidewall when hauling or in the rears when towing for a smoother ride drop down 8 to 10 psi, my 315's were 50psi max and at 42psi they rode great.

 

I just put 305x65x18 BFG AT KO's - 33.7" tires - on and was wondering the same about about the PSI. Tire tag on door jam recommends 40psi, this is what dealer set them at when new tires were installed. Truck came stock with the Goodyears but these tires have a much higher max psi rating.
