2004 Porsche 996 Carrera 4S

Tyres again Laughing

PS2 or PSC2 for the rears?

The cups are a track derived tyre? but would I be best sticking with the PS2 as an all-rounder, better in the wet and lower cost? (No track days planned for me Hand).

I have also read that you can put 35's on the front but I don't understand this with the 4WD/rolling radius and Porsche's recommended 225/40 profile for the 4S.

Any advice much appreciated Thumb

2010 Porsche 997 GT3

The Cup 2 is perfectly okay in the wet, but it doesn't really like the cold very much. I certainly wouldn't mix Cup with non-Cup across axles on a car though (they each will behave very differently with conditions and you would nominally expect a frustrating level of inconsistency). All 4 or stay with what you have would be my opinion.

There are enough people out there running 235s on the fronts of Turbos that I wouldn't personally be overly concerned about using those with 295s on the back - it all ought to be within tolerances. There is almost certainly someone on here who has tried it and can comment from direct experience though?

I've just ordered PS2 rears and PS4 fronts. IMHO the last thing the rear of a C4S needs is more grip.

I would prefer a matching set but struggling to source all 4 the same online. Would PS2/PS4 combo be okay or would you still say not to mix them up?

Thumb May go same route as that if it's ok to mix the tyres

I'll let you know next week assuming I've not died in a fireball caused by rampant oversteer!
