Default Re: Is 32 psi the correct tire pressure for 19"?

245/35/19 and 285/30/19. Running about 35 all around with no issues. I was tempted to go higher when I read beginning of this thread but after hearing about uneven wear, etc, I will stay the way I am. No issues, no uneven wear, just a wish for better gas mileage but my foot may have more control over that than an extra PSI or 5.

I saw this thread last night and almost **** my pants, I've been running 41/48 for a little over 3 weeks now. I knew that those numbers seemed high, but I figured why would they put anything other than the recommended pressures in the door jam.

I will be dropping my pressures down to 33/35. I hope my tread isn't FUBAR'ed.

You should be fine. 3 weeks won't do much damage unless you were doing donuts. I'm still around 35 psi on my second set of tires and it's wearing down evenly.

33/35 or 35 all around. From my experience with my last set of tires which was running 38 all around was having wear result from over-inflation. Now I'm just running 33/35 and so far wear on tire has been even. I never have more than 4 people in my car so there is never a need for higher psi pressure.

I do 36 all around. Too bad there is no right answer to this question, it would make things easier. If you think about it, the tire pressure you inflate it too only stays the same for a week or so, over time you lose cold tire pressure. So just a thought, I fill my tires with air when it gets down to 32psi, about a month or 2, so technically I've run anywhere from 32-36 psi due to normal tire pressure loss. Just a thought.

Default Re: Is 32 psi the correct tire pressure for 19"?

Sorry to dig up an old thread, I recently upgraded to 19" Apex Racing PS-7's, 245/35F and 275/30R (Michelin Pilot Super Sport tires).

My manual lists 33/35 f/r for normal pressure. I'm wondering since my tires are wider than stock, if that would change the pressure requirement?

Thanks in advance!

No they shouldn't. But I would increase the pressure to the 39/46 which I iirc is the pressure max ocupants.

You know what though, experiment a little, just don't surpass the max/min numbers. High pressures will increase response, decrease smoothness and lower pressures will do the opposite. I would not exceed the max rated tire pressure molded on the tire, nor ride around at that pressure.

Lower pressure increases grip, until the tire starts to cup or roll over. On the street I run 36psi all the way around. Tire wear has been pretty good. I got 25k miles out of my last set of RE11 on my setup where I can't rotate...mostly street miles and few track days mixed in.
