    Suggestions re Snow Tires & Wheels? Cell Phone Integration?

    My 977 S arrives in November.

    Any suggestions for snow tires (and wheels)? I understand 17" wheels are not an option due to brake size.

    Also, I'm getting a pre-configured car with no provision for cell phone integration. Does anyone know if a) cradle can be dealer added? b) any Bluetooth integration now or planned?

    The dealer didn't know on either count, so I'm forced to turn to the experts!

    PS: I'm a current M5 owner who has spent all too many hours on the bmwm5.com board. Great to find a Porsche messageboard of a similar very high caliber!

    Re: Suggestions re Snow Tires & Wheels? Cell Phone Integrati

    The dealer should be able to suggest you on the tires.
    And for the cell phone, there is nothing out yet for the 997 to be integrated to the PCM, but you can always install an aftermarket bluetooth car kit from either Nokia or Sony-Ericsson; or better yet just get a cell phone that has speaker phone; and from what I know most of the new high end models have this feature.

    Re: Suggestions re Snow Tires & Wheels? Cell Phone Integrati

    Winter Tire sizes are listed in the owner's manual on page 242. Wheel sizes are same as standard 18" or 19". Check with Tire Rack for possible winter wheel choices.

    Your dealer should get a TSB in time for the winter - if he hasn't already received it - which will indicate approved brands, types and sizes.
    "Approved" means the tires have been tested under winter conditions by Porsche, and passed.

    PS: I think an article listing winter tires for current models is generally printed in "Christophorus" every fall, from what I remember.

    Re: Suggestions re Snow Tires & Wheels? Cell Phone Integration?

    Thanks, Fritz.

    Hopefully the same is true for the US!

    The dealer didn't know and I called Tire Rack and they didn't either. They have not gotten feedback from Porsche, and are waiting to get their hands on a car to test, according the salesman.

    I don't get the car until November, but have found that, at least in the USA, the higher performance winter tires, particularly in larger sizes, tend to sell out quickly and I don't want to be stranded come December.

    Another case of salesman BS!

    Porsche will have done its snow tire testing LAST winter with prototype cars, so that they could make recommendations for this winter.
    Maybe Tire Rack would take a brand-new 997 and truckloads of tires to look for snow in the southern hemisphere during the next two weeks, so they would know what to stock by October '04?

    Re: Suggestions re Snow Tires & Wheels? Cell Phone Integration?

    Good point, Fritz. I think their plan would be to dest wheels and tires from a mechanical perspective. I'm new to Porsche ownership. If they will make actual recommendations with regard to brand this would obviously be best.

    This is my recollection as well. If only we knew what issue this was in.

    Re: Suggestions re Snow Tires & Wheels

    Porsche-approved winter tires for 997 models:

    18"
    Continental Winter Contact TS 810 N0 235/40 R18 91V M+S + 265/40 R18 97V M+S
    Pressures: F 2.5 bar, R 3.0 bar

    19"
    Continental Winter Contact TS 810 N0 235/35 R19 87V M+S + 295/30 R19 100V XL M+S
    or
    Pirelli Winter 240 SnowSport N0 235/35 R19 87V M+S + 295/30 R19 100V XL M+S

    Pressures: F 2.3 bar / 2.5 bar fully laden, R 2.7 bar / 3.0 bar fully laden

    Snow chains cannot be used with the 19" wheels

    Re: Suggestions re Snow Tires & Wheels

    Fritz,

    Thanks!

    Any input re the relative handling of the two solutions?

    Or is the 18" solution only for the Carrera and the 19" only for the S?

    My perspective is the current E39 M5 where BMW's recommended solution was 17" wheels versus the standard 18" (maybe due to limited 18" snow tire availability) and 235 all round versus the standard 275 rear, 245 front.

    I will have the S and certainly the 19" solution is attractive because one doesn't need to buy new wheels, but is it advisable? Do 295 width rear snow tires make sense?

    Paul

    Re: Suggestions re Snow Tires & Wheels

    Since I live in the Northeast I will definitely purchase winter tires. Now the real question -- when you have two sets of tires (one for winter and the other for the rest of the year) how do you store the set that is not in use? Can you purchase tire brackets/wall mounts?

    Thanks.

    Re: Suggestions re Snow Tires & Wheels

    As many said here, Porsche dealer should provide you with so called winter package of tires for your 911 (that come with rims too).

    I drive my 996TT during all seasons and use Porsche winter package of Pirelli winter tires that I bought from my Porsche dealership.

    997 Driver's Manual just says "911 Carrera S: Summer tires 19" only", implying that 18" winter tires are approved for both standard and S models.

    TSB particularly recommends 18" Contis and 19" Pirellis for "all conditions", and 19" Contis for "frequent Autobahn (Highway) trips", so you have to draw your own conclusions.

    As mentioned above, use of snow chains is not approved in conjunction with 19" winter tires, so this could be decisive for some owners.

    Re your comment about not having to buy a 2nd set of wheels, it is not to be recommended that you use one set of wheels all year round, and swop tires every spring and fall, because of potential damage to tire beads resulting from several changes. (You might find winter tires lasting several winters, depending on length of season and your winter mileage). Spare set of wheels might be a good investment, also giving you more freedom to choose whether to go with/without option of using chains.

    Hope this helps.

    You certainly can in the parts of Europe where use of winter tires is usual. I'd have thought you'd find them at Sears, Ace or Home Depot in the northern states, but can't be sure because they are not the sort of thing I've looked for when I've visited the USA. Anybody out there with local knowledge?

    Good space-saver, if available, is a free-standing vertical spindle, where wheels are stored flat, one on top of the other.

    PS: Maybe your car dealer or tire outlet will provide a storage service?

    Re: Suggestions re Snow Tires & Wheels

    Here is a link to a simple storage hanger for tires/wheels.

    Re: Suggestions re Snow Tires & Wheels

    Fritz,

    Good point re the potential for damage when swapping tires on the same wheels. I had heard that before. I do currently have a full snow wheel/tire set for my M5.

    The other part of my question that I would appreciate your feedback on is the issue of using the standard 911 rear tire witdth of 295 for snow tires.

    BMW recommends a much narrower (especially rear) wheel/tire for winter/snow for the M5.

    But if the standard width and size is OK, certainly aesthetically I'd prefer!

    Re: Suggestions re Snow Tires & Wheels? Cell Phone Integration?

    There is no cell phone intergration in the U.S., at least not with the keypad. I wrote a letter to Porsche today, I'll post it.

    I remember a BMW 1602 I once owned had lousy traction on snow, because the driven rear wheels had so little weight on them. That's not a problem the 911 has.

    I can't comment on the different abilities of the two tires, other than to say that - since you live in Short Hills, NJ, - even the tire with less traction should be adequate to get you home!

    Sorry, couldn't resist that.

    Seriously though, I would doubt that there would be that big a difference in their respective abilities, otherwise they wouldn't have been approved for fitting.

    Re: Suggestions re Snow Tires & Wheels

    Fritz,

    Your explanation makes sense since I assume Porsche knows what they are talking about and BMW also!!

    However, I must also say that I just got off the phone with Tire Rack, to see if they are or will be stocking the recommended tires (they won't and say they will not be available in the USA - only the Conti TS 790 and Pirelli Sotto Zero in these sizes), and they repeated the mantra that snow wheels/tires should be as narrow as possible.

    Oh, well. Hopefully Porsche dealers will have the recommended tires and not rape us price-wise!
