Hi

I want to replace the tires, but porsche is charging double the price. I want to put some pzeros on them.

Stick to OEM sizes and you’ll be fine. Never heard of a warranty denial because of tire replacement.

Only possible issue might be using slicks on a track.
Otherwise, it matters not.

Plain answer is no. The Magnusson Moss Act says that the modification has to directly cause the failure of the warrantied part.

thanks guys, One more question, sorry if this is stupid.
Does this configuration seems right?235 for the front and 265 for the rear

Scrounger

Thats correct

Not quite: the sizes are correct but the type is not; the rears are N-Spec the fronts are not. You don’t want to mix and match N-spec and not-N-spec.

good spot, thanks.

Slicks are specifically discussed in the gt4 owners manual as voiding the warranty. They provide more lateral grip than the oil pumps can handle.

Any street tire is fine. People can and do put all sorts of tires on for different reasons.

Note that CPO valuation depends on having N-spec tires, in case that's a consideration for the OP.

Try TireRack. You can put in the model of your car and the appropriate options will come up. I’ve used them a lot and always had a good experience. They have certified and installers, too, based on your zip code. That’s how I found Great Falls Exxon - great place.
