Correct PSI for 19's
 

I've got 19" staggered setup and just wondering what is the best psi to set. Is it the same as stock 18's or is it different? Thanks in advance for the help.

Whatever the tire recommends.

my falken 4453's say 50 psi

50 psi is the max psi for the tire. On your car, it depends on your set up. Stretch/no stretch, mad tyte camber/factory specs will determine what kind of psi you should use.

35 psi.

I usually run 38 to 40 PSI, you can do a chalk test across your tread of the tires and get it just right.

That psi is pretty low. Have you had any problems with losing the bead or sidewall bubbling?

35 psi front and 38 psi rear. Recommended OEM pressures, on OEM size tires.

Go with your OEM tire pressure specs. It does not matter what size tires you use.

So stagger setup is 35 front / 37 psi rear.
You can go 1-3 psi higher though

As you drive in a longer duration or in hot weather climate. The tire pressure will increase. So you would not want it to be on Max Psi. Hope this helps.

I use 40 psi...

I just put them at OE specs but bumped up just a few.

Lexus recommends 35/38psi F/R for the ISx50 with 19-inch wheels, just like the 17 and 18-inch factory option wheels.

Tire pressure is always posted on a sticker on the inside panel of your driver side door. 35/38 F/R
