    Simple tire questions

    Originally, I have 295/30/19 Michelins PS2 on my Carrera 2S rear wheels. Now the questions:
    1. Can I put 305/30/19 PS2's on my original rims?
    2. Is there an official Porsche point of view regarding this?
    3. Has any Rennteam member done so? Personal feedback regarding car performance/handling before/after swap.
    4. Does tire pressure require changing with the swap?

    Let me know what you think.

    I think you can do it with no issues. I asked that question before.

    Why would you bit wider tires on? I would stick to the factory specifications (N rated tires).

    I don't think so. Maybe call Ruf and ask them. I found their 295/30 wheels were specified for the 997 but not for the Turbo. You'd figure they'd spec the 295/30 (997)wheels for the 305/30 Turbo if they were ok to use. Leads me to conclude your plans would not be approved by Ruf. FWIW.

    I ordered the XRR rims for my car and they came with 305s in the rear. There is little difference between a 295 and a 305. Should be able to. It's only 1/2 an inch!

    Re: Simple tire questions

    Has been done here by a few...me in about a week too. I think it'll fill the rim width better like the front and look better. And yes...the pressure must be lowered to 1 atmosphere to remove the 295's then increased again when the 305's are mounted. sorry
