    Winter tyres for 991 GT3

    Because the late delivery date of my car I think it needs winter tyres very quickly. Are there members who have experience with this?(on previous models of GT3)  Which ones would you recommend?

    Thank you very much!

    One of the best current generation snow tires is the Dunlop SP Winter Sport 3D, but it isn't N rated. The Pirelli Sottozero are but to some it's a inferior tire compared with the Dunlops. Not sure if they come in 991 sizes but they are available in 997 sizes.


    Re: Winter tyres for 991 GT3

    Do you know why your car is delayed??

    It seems that there is some factory issue on the GT3 but no one is prepared to reveal what that problem is...

    How much has your car been delayed?

    Back to your question - there were done videos on here (I think) 'recently' on a 991 testing different winter tyres - it was. Michelin promotion, but the new improved 'Alipini' seem to perform the best!

    As these were tested on a 991 I would assume they come in 20" to fit a GT3.

    Unfortunately no, not yet. I have posted this question online on several pages but no one can't seem to get the reason of the delay. Some do know but can't tell. This makes me worried to be honest. Quite a substantial delay already.

    Thank you for your reply. Gonna look into that.

    Sorry about that. No need to be worried though but it may take some time.

    Your dealer can actually find out (if YOU insist), so... Smiley

    Can you help us with an indication of the time frame?

    Last thing I heard was mid/end of October for first production of customer cars but like I said before, I do not work for Porsche and we need to rely on rumors.

    IF people are going for winter tyres, will you get them mounted on the same set of wheels? Or will you get a winter set= wheels+tyres?

    Re: Winter tyres for 991 GT3

    I think that even today it has a lot to do with how many miles you put on the car!

    My Mom (in the 70's) put a relatively few miles on the car, but my Dad was one of the first to recognize that you should put snow tires on all four, not just the "driving" tires. (which would have been rear tire drive at the time).

    That Benz looked a bit silly, but kind of bad a$$ with awesone snow tires on all four; but due to few miles driven he did buy extra rims to avoid re-mounting any existing tires.

    He didn't get quite so extreme with his own Benz or the later Ford that he inherited from my Mom's mom, but he did always mount snow tires on another set of rims from the regular tires. 

    Considering that he did posses at least a bubble balance scale with all of the counter weights, I would have gladly helped him to re-mount tires; but he already knew that tires are best left on the rims that they are already on (many shops will not even re-mount used tires).!!!!!

    I at least have memories of helping to change on or off winter tires, but driving an early 70's 280 SEL with all winter tires in snow conditions (Priceless).

    It is not good for the tyre wall to be mounted and demounted . Unless you throw away the set of tires you dismount , I would definitely get a set of rims specially for the winter tires ( a cheaper one )

    I was in Switzerland last week and most cars had rather not so nice wheels with their mandatory winter tyres. It seems that for many people winter wheels+tyres are for utility rather than for look and performanceSmiley

    That surprises me too, people spend a lot on their cars and then drive 6 months with crappy wheels.

    Re: Winter tyres for 991 GT3

    Yes, surprising.  Seems like they accept their cars look crappy for a few months and don't care ("it's winter").  I use the OE 19" wheels with some Bridgestone Blizzaks.  Works very well.  I use different wheels/tyres in summer.

    It's not mandatory to have winter tyres in Switzerland (unlike e.g. Austria) but if you get caught in conditions that require them and you don't have them then you are in trouble.  If you e.g. only drive on nice days with good weather then there is no problem.

    Is there even an 'approved' winter tyre setup for a 991 GT3?  The other thing I wonder is if it has the same under-body sealants and protection that regular models have (I remember some older model RSs didn't..).

    Re: Winter tyres for 991 GT3

    I actually like the ' crappy' winter look. Nothing better then back steel rims for the winter indecision  …. so , in spring, when you put back on nice rims , you think you have a new car . My wife, who is not Swiss, does nut understand that either and thinks black steel rims are horrible .

    As Dave said, winter tires are not mandatory , but if you have an accident and you did not have the ' proper tires for the road conditions ' insurances with not cover .

    Re: Winter tyres for 991 GT3

    I was in Zurich and around. The weather was dry and mostly sunny and very pleasant but freeeezing, coming from 25 degrees at home. Good thing I went prepared with clothing.

    Relatively, a lot of Porsches mostly Cayenne but also Panameras and newer 911s were noticeable.

    Given the climate and the low temperatures even when dry, it is very wise to fit winter tyres during the 3-4 winter months.

    A lot of people probably do as I did and buy winter wheels and tyres as a package deal from the car manufacturers' dealers, either with the car or at the onset of the first winter. For "bread-and-butter" cars, the wheels are then generally black pressed steel ones rather than light alloy.

    I can only quote a Pirelli engineer. His business has to do with AMG and Porsche tire specifications.
    He told me in a private held talk last weekend, that several (de-)mountings are not a problem. So one mount and demount per year over a period of, let's say 4 years, is ok. When the intention is to use a tire set over a longer period, he recommended to use a seperate wheel set, because the tire is loosing it's "flexibility" bit by bit. A sporty summer or winter tire, which last only three seasons when "proper" used, has only three mounts and two demounts during it's lifetime.

    Thank you for sharing this information, I like the 21" wheels on my ML63 and I don't want to run uglier wheels for the winter so mount/demounting it is - with a 4 year limit Smiley

    I always used the same rims for winter and summer tires without an issue for what it's worth.

    I had always thought / been told to be careful with extra demounting on tires with low profile walls .

    But probably it is ok if done only a few times …. Smiley

    It can be very bad if the tire wall is damaged and this usually happens from the "inside" and it is not visible.

    I know that many people do it but if nothing has happened so far, they have been lucky. Nothing more and nothing less.

    I wouldn't take the risk but to each his own I guess (if you are doing skydiving and other dangerous stuff, you may want to add this to your vast experience of taking unnecessary risks Smiley...yes, you know who you are Smiley Smiley) but with kids and certain responsibilities, I started to reduce risks, not increase them. Smiley

    As a general rule: Low profile (below 60) and/or tires over 18'' diameter and/or V/Y/Z speed index tires shouldn't be removed and re-mounted but I guess you shouldn't smoke, drink and take drugs either but people tend to ignore that too.  Smiley

    It doesn't necessarily need to cause real "damage" to the tyre to be a problem. Tyres on high performance cars can tend to wander slightly around the rim if the tension in the bead is inadequate. I have known of instances of this happening even to new tyres. It can cause the tyre/wheel combination to become unbalanced, causing vibration when the car is travelling at speed. 
    If a tyre is dismounted and remounted on a rim several times, it increases the risk of the bead tension being reduced. Why risk it unnecessarily?

    I agree on that thought, especially on low-profile tires. It is similar to the damages that can occur due to climbing curbs, these damages are not visible on the outside. 


    Re: Winter tyres for 991 GT3

    I am always present at the workshop where they fit my tyres and I can tell you it is a real struggle to fit the 295/30 19 tyres on the wheels. The bead is very hard and force is exercised. I can imagine that if the process is repeated it might cause some distortion/damage.

    The technician told me that the Bridgestones are the most difficult to mount and the Michelin relatively the easiest.
