    What's the difference?

    I'm planning to change the Pirellis on my CGTS to Michellin Pilot 4S tires. Ordering from Tire Rackicon.

    These choices came up. Different prices so what's the difference? Which one should I buy for my car?

    Cheaper set appears to be "green" tires - less rolling resistance/better mileage. Probably have to give up a bit of traction if this is so.

    Second set are Porsche approved (N0 rating) while the first set aren't. That alone may account for the extra price!

    Re: What's the difference?

    The PS4S tires were designed as reasonable road tires for high end sports cars and super cars.
    Porsche N spec tires go through testing and occasionally slight changes to make them optimal for Porsches. It's basically just a stamp that says "Porsche Approved."

    For most people, it is impossible to tell the difference in handling characteristics between a regular tire and an N tire of the same brand/model.

    If you plan to keep this car through a few sets of tires, you might as well go with the cheaper option. But if you plan to resell this car in the near future, having an N spec tire is a selling perk to many buyers.

    Also keep in mind that some warranty items may be voided by using a non N spec tires.

    I assume theres no difference in the ride quality and importantly to me being smoother and quieter than the Pirellis.

    Re: What's the difference?

    Porsche works with tire manufacturers to "optimize" a tires performance specifically for Porsche cars. Hence the "N" designation and additional cost. The generic model is more of a compromise to adapt to a variety of car manufacturers. Will you notice the difference? Maybe yes, maybe no. It's really your call. You'll see that BMW, Mercedes, Ferrari amongst other also have tire specifically designed for their cars.

    In any case, most will agree that the Michelins are the preferred way to go.

    Would it be entirely too cynical to think the tires are exactly the same with the exception of the N0 designation on the sidewall of the tire?

    It is possible. I haven't seen any bulletins on what Porsche may have changed with the PS4S.
