Thanks for puttin this into perspective. The one thing that sucks is... shouldn't the dealership where one spent $115k or so be able to ffer at least better advice than varying front and rear tires altogether.... I must say this has been quite a sticking point with my Porsche experience.... the service at the dealership has been much under par. Anyone needing more information in Central Florida can just ask by PM.
A gret forum indeed. I have asked once in the past, but will do so again; How does one go about gettting a lifetime membership?

Mike. Thanks so much for that. I'll set the little alrm warning 2 mph earlier than now if it means a greater choice of tires... honnestly; whatever speed I'm going, 2 mph won't make or break the deal.

You can sign up for 1 or 2 year memberships by clicking the "premium membership" tab in the header bar at the top of the page. I don't know how the lifetime membership thing works. You can e-mail one of the moderators directly and ask.

Isn't the diameter of the 991 wheel larger than that of the 997? In which case you'd sacrifice acceleration and speedo accuracy.
If you go to the dealer they should recommend only n-rated tires. There may be some other stuff on tirerack that is also good but lacks the n-rating.

I would be wary of messing with that from a performance standpoint, but OTOH it seems to work for others:

My bad, I wasn't clear. The wheels may both be 20" but the 991 wheel/tire setup is a larger diameter than the 997. So putting a 991 wheel/tire fitment on a 997 will change the speedo/odo/acceleration/suspension and whatever else Porsche engineered to work with the smaller wheel/tire diameter.

) I also doubt changing to a 295 tire will cause suspension problems or a noticeable difference in acceleration.You have a point, however. Something as simple as going one size larger on a wheel ends up causing other issues down the road. The OP wants a wider tire selection and this is the only way to do it with the wheels he has. It doesn't seem unreasonable to me, but there are almost always trade-offs.

well; as it is I'm just going to replace the rear with same Pirellis. Not my first preference, but I'm counting on more sizes being available in 20" in a year and half or two and will change then.

Hi Mike,
That is absolutely correct; I do have 20" tires - not stock and I have asked the dealership about sizing and tires used on the 991... no straight answer yet. By now, I'm guessing many of you are thinking I need to look elsewhere for service.... if you are thinking that; I would second the thought. The tire slection is far down my list of considerations for changing.
The only thing holding me back is that I live in the boonies and that 1h15mn is plnety far enough without wanting to add any Xtra time for service (Also where I bought new... you'd think service would be up to par!)
At this point and not knowing any better, I'm thinking either:
- Bite the bullet and replace the rears with what I have (not happy with that!)
- Probably Continental's?
- I don't think I want the Yokohamas
If anyone knows of another set of tires to consider or a website which will list all options; I'm all ears!

2. NEW Pirelli Pzero (not Rosso) is much much better tire and comes OEM on 991
3. Yoko and Conti both make good tires, I've had both with no issues
4. PSS is a great tire, PS2 dry performance, better in wet, and better wear
So, what I recommend is:
- See how much is left in fronts
- If you got LESS tread than a full cycle of rears, then just do all four
- If you got more tread left, compare the cost of rear Pzero N-rated vs. a full set of contis/Yoko... if costs are not too far out, do them all
- Bridgestone S04 is also highly recommended, it's 2nd rated behind PSS
Good luck!

I don't mean to hijack this thread but my question relates to the topic.
I'll need a pair of rear tires very soon and I was thinking about Michelin PPS rather than PS2. It'll be the 295 /30 /19 size. So my question is will the PSS rear 'compliment' the PS2 235's that I have on the front.

They aren't totally against mixing tires under certain circumstances, but it's definitely not the best option.

One morning recently, I climbed out of bed in the dark, and slipped my feet into my rubber soled moccasins and walked to the kitchen. In a few steps, I nearly fell down. The problem, I had put the slippers on the wrong feet. I immediately thought about the comparison to mixing tires on a car. Sure, you can do it. Sure, it will get you from one point to another. But you run the risk of breaking your neck.
......just an observation.
