What's the recommended Tire Pressure for a 2008 Turbo w/20" ?

I've noticed this on the driver side

Cold Inflation

Front: 39psi
Rear: 49psi

 

Sorry but you left me no choice.........RTFM................BTW that sounds about right for pressure. Do you have TPMS?

 

No TPMS

 

39/49 is for fully loaded. I believe partial loaded is something like 39/43? As said, its in the manual.

 

Yea that seems right 39/43.....49 is alittle to much.

 

39/49 is what the recommended psi is. States this on the inside of the door.

That honestly seems very high to me though, I believe when I purchased the car it was 39/43.

Today I filled all tires with nitrogen so that should help with the stability of the psi.
I filled it 39/49 just to see how stiff it was, and wow, very stiff and bumpy. I feel every single little pebble on the road.

I think tomorrow, I will deflate back to 39/40 front and 43/44 rear.

 

That is correct guys.......sticker in door is fully loaded.......39 front, 43 rear

 

hmm im at 37-39 front, 49-50 rear -- as is from the dealer for the past couple months.
maybe i should lower it to get a smoother ride

 

Don't use the loaded number unless you have the load. You'll just increase uneven tire wear. Ask me how I know.
You'll get much better wear at the lower recommended settings.

 

ya, I'm lowering back to 39/43.
That felt much better, and I guess that the wear is better as well.

 

wow it's strange, because i just double checked and it says 43psi for rears and 39 psi for fronts. I might also think about lowering rears though...

 

And, if your fronts are ever 42+, you'll notice this weird, jumpy behaviour in the steering.

 

ahh, went back down to 39/40 fronts and 43/44 for the rear, and WOW, so much smoother.

 

pressure recommendation for 22" tech arts?
i think i am running 44psi on all 4
thx
