EV tires best for Taycans

[Poshfpg]

Those are too narrow for RS Spyder rims.

MY25 cars have narrower rims and these tyres.

I appreciate I am a huge cynic, but the N rating piece is more about manufacturer deals than anything genuinely material on the tyre's abilities on any given car.

They are so slow with the ratings that if you stick religiously to what they insist on, you often have tyres that are several generations older than the best tyres available.

If they rate a 285, they're going to need a really good excuse not to accept a 305 of the same type.

Of course dealers won't fit them necessarily as there will be supply deals happening that will cause issues (my cynical view).

I've never stuck to marque "certified" tyres across a number of performance marques and have always had far better performance than the originally specified tyres.

YMMV.

(BTW, I have also yet to find a main dealer who is cheaper for the exact same tyres than you can get elsewhere. Often by a very large margin - £100+ per tyre in some cases).

Frank @f1eng would suggest N rating is a very real thing and we all bow to his knowledge in technical areas. As a result I held off until they were N rated in other sizes meaning while possibly slightly different in construction there wouldn't be a significant difference. Agree on the cost issue, shopping around can save serious £s.

Tyres are use case specific, it's our main family car so can have bike rack, roof box and dog in boot on long trips so increased efficiency is of primary importance. For the number of times I blast an Alpine road I can take a slight loss of on the edge handling for 15% + more range getting to said Alpine road.

There is no insurance issue at all, if they tyres meet weight size requirements and are UK legal you are fine.

This isn't a tyre size for 21" RS Spyders?

Sorry, I'll try to be more specific in my replies in future

lol well the problem is it won’t fit anything other than the gen 2 wheels I don’t think and I’m over-cautious so will go with N rated. As you say: pretty sure it makes little difference and I wish that PS4’s were N rated as they’re my favourite tyres.

Frank was a hero of mine growing up (honestly) and has more technical expertise in this domain than I do.

But...

As noted I do have 25yrs of driving high performance road cars whose manufacturers had "approved" tyre arrangements, and used "non-approved" tyres on them all. I never once had an issue and invariably the tyres performed better than the OEM "approveds".

Pirelli were often the approved ones, and switching to Michelin Pilot Sports, without fail, gave tyres that made the cars much, much nicer to drive. (As an example. My switch here was to Hankooks as am curious in what they do to range).

I'm at ease with going off piste on this one as a result. Especially as Porsche approve the same tyre just 20mm narrower.

Ask yourself what happens when cars get older and manufacturers stop producing a marque/model specific tyre...is the car then a write off?

Absolutely not, I just can't be bothered arguing with Porsche if there is a warranty issue. I concede that it's a marketing exercise, just not one I'm that bothered about arguing about. I'll add that the Asym's I've had on my car give awesome grip, feel and fall off progressively, so am pretty happy with them

Manufacturer rating can actually be a double edged sword. On one hand, manufacturers may negotiate slight tweaks to the tire features which will benefit the consumer, on the other hand, they may ask for features to help the manufacturer, such as cost optimize them by omitting something that the manufacturer doesn't consider a "must have" while saving the manufacturer money, or make the tire last longer in lieu of performance (or vice versa) to satisfy whatever metric marketing is looking to showcase. For mass produced cars, often the manufacturer rated tires are compromises on all fronts to make them least expensive.

Personally I look at the tire performance specs, manufacturer rating is secondary. I currently have 3 sets of tires for my Taycan:

• 20" all season Conti Pro Contact RX - NF0 rated (came with the car)
• GoodYear 20" winter UltraGrip Performance Gen-1 - NF0 rated
• Michelin 21" summer PilotSport 4S - not NF0 rated

So you also only charge from Porsche branded chargers (AC and DC), wash the car with Porsche soap and wipe with Porsche branded towels, etc, all for that same reason?

I don't think Porsche would argue a warranty issue on charging with a non-Porsche charger, but they might with tyres. As I said: a lot of the decision is based around the fact I've actually been pretty happy with the tyres. I know @f1eng has said he is pretty happy with the Goodyear's as well

Soap you say?!

Personally I would think they could easier argue non-Porsche chargers damaging the battery system more than non-Porsche tires damaging anything. What could possibly non-Porsche tired cause, vibrations at frequencies Porsche is not designed for? Same vibrations could be cause by the type of the road you're driving on too, Porsche can't claim you can only drive on Porsche approved roads.

There have been examples of public DC chargers frying EV's, can you think of any examples of non-manufacturer rated tire (still rated for proper weight/speed/type of vehicle) that would damage the car?

No, but I understand Porsche rating tyres and being a little picky about it. The issue is how long and expensive Porsche make it for companies to do this. Tyres are the only thing that attaches the car to the road, so they’re a hugely important component of the car and I do understand Porsche having a ‘rated tyre’ certification. I’ve experienced firsthand how bad a set of tyres can be.
But the fact they don’t certify top-end tyres quickly and give the owners more choice of a rated tyre, is pretty rubbish.

It'd be interesting to see how different, if at all, the Hankook tyres are in terms of compound and construction between the 285 and the 305...

I find it hard to believe they are any different at all other than moulding. I might write to them and see ?

I heard rumour that Porsche are relaxing the warranty angle on N rated tyres, but have yet to see that written down. Will ask on that one too.

The certification thing would be more understandable if the tyres were actually better...but IME they rarely are.

Would love to hear your experience with the Hankooks. It’s time to replace the 21” Pirelli’s on the Spyder wheels on our GTS. Looking for better wear, less road noise and higher efficiency. Thanks

So far I think things are very positive.

I’ve not yet had a run at speed, so not yet sure how they sound on the motorway, but so far I’ve found to be MUCH quieter, so much so that I’m hearing the wine of 1st gear a lot more when in sport mode when going slowly.

erformance seems good, grip reasonable enough - again, not really had time to going on a spirited run, but generally really pleased.

I don’t think the ride is quite a smooth as the Pirelli’s were - particularly in sport and sport plus.

The rears look a little ‘stretched’, almost like they should have a wider profile!

Thanks so much for the feedback. Really appreciate it. Have always felt that the 21” Pirelli’s on our GTS were noisy. Now that we have 12,000 miles on it and the tread depth is close to the wear bars, the road noise is more pronounced. Here are a couple of pictures of a MY2025 Taycan Turbo S with 21” Aero wheels which came fitted with Hankooks. I also noticed that the rears seemed “stretched”. If a 315 were available, it might be a better fit.

Yup, you will fail the check for Porsche Approved extended warranty if you don't have NF0 certified tires. A service guy at Porsche service told me this is the most common reason to fail the check.

Not true in the UK.
