    I m running 35s on 20 inch TSS wheels with Pro-comp All Terrain tires. I was wondering what PSI you all running on Tundra.

    I began with 50PSI front and rear and the ride was too bouncy. I then changed to 43 and it feels better now. I wanted to try 40 but wasn't sure if it will effect the tires. I m not towing and no load on the bed either.

    Before anyone post,
    "open the driver side door and look at the sticker for the tire pressure "
    The above has already been done and it states 50PSI for my 33 inch LT tires that the truck came with. I changed the tires from 33 to 35s.

    Is your tire 35x11.5 or 35x12.5 or wider. They typically have different maximum psi ratings. Wider tires have max psi of 65 and narrower ones have 80 max psi.

    Mine has 80 psi max and I run them at 45 psi.

    My tire size is 35x12.50x20

    I should b ok at 42-43psi. Do you go above 45psi when you are towing? I just don't want to go too low and damage the tire...

    You won't damage the tire. Over inflation, on the other hand, will do damage due to abnormal wear.

    I noticed that for some reason Toyota puts mine at 37 each time I go. Should I bump it up some? (275/70/18)

    I was wondering this same thing. I just started doing my own oil changes and tire rotations since i just got out of the 2yr/25k mile service range. I rotated my tires and checked air pressure for the first time in two years. Now before people think why wouldn't you check your pressure more often.....Answer: this is my third Toyota and 2nd lifted with wheels and tires from the dealer. I about drove down to Toyota and lost my mind. They were at 26 psi. I started searching around here and found a thread where people were running them at various psi's to see if it effected fuel mileage. I set mine to 39(over shot 38 at a gas station and didn't feel like playing the back and forth game so left it there). Crazy thing is I have never gotten a Tire Pressure light. I am almost positive they never put sensors in these rims and never disclosed it.
    Anyway to answer your question 39 now i have no idea what it was before. I have Pro Comp MT's and surprisingly don't have any crazy tread wear. Tires have just over 18k on them.

    I know the post title is 35's, but I am running 37x12.50 nitto G2 on oem 18" wheels and run mine at 33-34 psi daily driving and run them at 60 psi towing. This is a 10ply E-rated tire and our trucks are not that heavy. Anything much greater than the 35psi and it effects the ride quality. Tires wearing great at 33psi.

    Good to know. 37's are what I'm planning on getting when it's time to replace these 35's. Hopefully I can space it like gears next year tires the year after. I have been trying to remember what I used to run my 35's at in my f250 as a comparison but that was back in 2011. I have noticed that at 39 psi the ride feels a bit stiffer then down at 26. I may split that difference and try the 33 your running.

    Let me try 35 on my 35s tomorrow.
    Let's see if I notice the difference. Was a huge difference from 50 to 43

    I m glad I found someone running Procomp here. I m running Procomp AT and I m pretty happy so far. I will try 35psi tomorrow and see if I notice a difference. 50 was too bouncy but 43 wasn't too bad. Guess somewhere between 35-38 should work.

    I have a 285x55x20 Yokohama M322 tires. Which psi you guys recommend. I just noticed front looking lower than what I am used to seeing when I bought it used. I measured from the floor to the fender on a straight line front is at 40'" and rear is at 42". I remember them looking level now I can clearly see front dipping
