My local tire shop has suggested running a little higher pressure in the fronts for sharper turn in, I use about 32-33 psi(2.25 bar).

Suggestion

what your tire pressure should be, but I have the 17" Pirelli PZeros, 50/205 up front, and 40/255 in the rear, the recommended pressure on these are 36 psi on the rear, and 29 upfront.....This seems to work well with mine...Yours are probably a few psi higher front and rear.....

Suggestion

The Porsche recammendation is a tad low for the fronts for safety(I guess to induce understeer instead of oversteer if you overcook a corner) I run 33/36 Front/rear

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

I need to know the accurate tyre pressure for boxster 2.5 MY99, manual transmission. 225/40ZR18 and 265/35 ZR18 Pirelli Pzero Rosso N4. Now I put 2.0bar front and 2.5 rear, but I am not sure because car left the road in a curve and rear center tyres is consumed, however edges are brand-new. (overpressure?) A web by delticom holds correct pressures are 2.0bar front and rear for boxster 2.5 wheel 18". I would estimate all your help. Regards.

POST 2Original post

what your tire pressure should be, but I have the 17" Pirelli PZeros, 50/205 up front, and 40/255 in the rear, the recommended pressure on these are 36 psi on the rear, and 29 upfront.....This seems to work well with mine...Yours are probably a few psi higher front and rear..... When I first purchased the car, the back tires were about 10 psi low ......and the outside of the tires are worn a bit more than the center/inside, given the camber on the rears.....So it makes sense that if your center is worn, but your outsides are OK, you may very well be overinflated..... Lou

POST 3 / ORIGINAL POSTEROriginal post

then, which pressures (in bar) are accurate?

POST 4Original post

mathematically, 36 psi = 2.48 bars 29 psi = 1.99 bars so 2.5 bars (rear) and 2.0 bars (front) match the manufacturer's recommendations. My local tire shop has suggested running a little higher pressure in the fronts for sharper turn in, I use about 32-33 psi(2.25 bar). But I'm fairly new to the car.

POST 6Original post

Limon is right. The Porsche recammendation is a tad low for the fronts for safety(I guess to induce understeer instead of oversteer if you overcook a corner) I run 33/36 Front/rear
