Hi there


Fitted some Pirelli Corsa N1 tyres today from a GT3 on my 997.1 C2S, they are 235/35/19 and 305/30/19.

I believe Porsche/Pirelli recommend recommend 29psi front and 31psi cold pressures, can anyone confirm this please?

But a GT3 weighs 1395kg, compared to my C2S which weighs 1430kg along with different tuned suspensions, though my car does have GT3 roll bars, LCA's and is running a fast road / track geo.

Should I also go with the same 29/31 cold pressures in my car or maybe something a little high, maybe 30/33 cold?

Lastly at the track what hot pressures should I aim for with these tyres?

P.S. Also fitted a set of OEwheels TPMS sensors and can confirm the work fine and at £150 far cheaper than the £500ish Porsche wanted.
