i got falken azenis RT-615 205/50/15 last week and never asked the tire people what psi should i set it at. I checked today it was around 40-45psi, i think thats kinda high. So whats the correct psi? btw the wheels are stock 99-00 si wheels, if that matters at all. Should i put it at factory psi f/33 r/35 or keep it at 40ish? And i searched, not many threads came up, but the ones that did didn't have any info with 99-00 si wheels.

Thanks.

 

The pressure depends on the car, not on the wheels.

I advise starting off at the factory recommendation for your car - I suspect you got it backwards and it's 35 front and 33 rear, not vice versa (it's 35F/33R on my Integras, anyway). Pressures measured when cold (i.e. with the car at the outside temperature in which it will be driven, after sitting out of the sun for several hours). Try it with that. If you feel the need to adjust the pressures from there, for handling, ride comfort, tire wear, etc, you can do so in 2 psi increments. But that's usually the best place to start.

 

I run 35 all around.
