All Season Tyres. Help please.

Well aware of that. What happens at lock up? ABS/ friction go off or does regen somehow pulse and achieve the same effect?

No pulsing regen AFAIK, regen full off on ABS engagement.

Thanks for clarifying the q. I’ll test and report back.

That’s why I want Novemberwhisky to watch the regen dial when braking. If it’s ABS during lockup regen should go to zero? Maybe it still blends regen even with ABS?

Those are interesting points. ABS with and without regen both seem plausible strategies.
The following statement is not 100% clear to me and I'm not prepared to pay for the paper from which it is abstracted, but here it is anyway:
Energy recovery, not just in the usual form as a major contribution to energy efficiency and increasing the range in day-to-day operation, but rather in this case – which is typical of Porsche, using the first electric Porsche sports car, the Taycan as the example – this also extends to the limits of driving dynamics, under extremely high lateral acceleration and during ABS control.

Any warranty issues there when these non-NF0 are mounted? I wonder if anyone had any issue with Porsche when they mounted NON NF0 tires....
How bad can the Michelin PA5 be as compared to their rated NF0....I even match their width spec....305 rear and 265 front, only diff is 21 inch instead of 20 inch as recommended by Porsche.

On another note, which tires do you select in PCM when using 21 inch winter, since this is not an option in PCM?.....21 inch all weather/season?

Cheers

Since dealers themselves hand over Taycans that are on non-NF0 winter tyres, I would not expect them to have a very strong case regards any warranty claims... Even in domestic official marketing material from Porsche, I have seen they use Taycans fitted with nordic winter tyres ie non-NF0.

Many Taycans in Norway will spend more months of the year on winter tyres, than they would on summer tyres. I use winters from October and into April or even May.

NFO (or any other manufacturer ratings) are just a recommendation, they cannot be constituted as ‘requirement’.

It is very similar to ICE cars; where the fuel cap will like have a recommendation about the fuel that the manufacturer recommends e.g. BMW’s usually have a line written ’… recommends Shell V-Power’.
Shell V-Power is E5 (or Octane 99), but the absolute minimum requirement is E10 (Octane 95) - E5 is only a recommendation & not a requirement for BMW M cars.

Similarly, manufacturer tyre ratings can only be a recommendation, not the rule.

I doubt any manufacturer (at least in UK/EU) will be able to void a warranty claim for using non NF0 or * approved tyres; as long as the tyre size, speed, load ratings are the same as the specification.

Anyone in the UK/EU have an actual case where manufacturer refused warranty claim for using non NFO tryres?

+ load rating for EVs especially (XL)

Correct… Tyre sizes, speed & load ratings are the absolute requirements…

I'd be more worried about the risk of insurance voiding cover. no idea if it might count as a non gem modification. Though i did note on a recent quote i had on different car that the insurer didn't view switching to winter tyres as a modification.

Equivalent tyres that match the factory fitting (size/speed/load) wouldn’t be considered a modification - especially on the same rims.

Otherwise virtually every car on the road today, not on its original rubber, would be in contravention of the terms of its insurance, in respect of ‘modifications’.

When I first started using winter tyres decades ago I checked with my insurer and they specified the same size as standard tyres wasn’t considered a modification.

Not sure about a Taycan with so many different “standard” wheels. I would guess going for 22” wheels would definitely need declaring to insurance in UK but would winter tyres on 21” when the Porsche supplied ones are of 20” or 19” ????

Agree. Just most cars don't have the equivalent of an N i guess.

I just wonder if i slid into a car carrier full of Veyrons, the insurer might check that bit!!

They let us all drive on summer tyres rather than all seasons and full winters. Which to my simple mind is more crazy especially when conditions are terrible and folk are slipping and sliding everywhere.

Not heard of anyone being denied a claim based on tyres in those situations. When clearly better tyres would make ALL the difference (and a steady right foot ??)

The UK insurance system is definitely different from here in the Netherlands. I do not see any exclusion in my policy on tires/rims.
In any case I have mounted brand new Michelin Pilot Alpin 5 on the 21 inch cross turismo OEM rims, I really think this will be fine also warranty wise, OEM wheel, with tire width that matches summer specs....
Time will tell.

It is obvious after watching hours of you tube videos and reading articles that All Season tyres are a much better winter option than winter tyres for the north of England where there is snow on the ground only 1 or 2 days a year.
However I need a tyre with the 3 mountain peak snowflake symbol so I can drive legally in Sweden and French Alps.
Michelin Cross Climate 2 and Good Year All season are all season tyres that have the mountain/snowflake symbol (as well as M+S) because of their optimised snow performance.
But I can’t find anything in the right size.
245 45 20 fronts
285 40 20 rears
The NFO official fit All season Pirelli Cinturato P7 is M+S only, furiously expensive and probably last less time than an F1 tyre.
Anybody running 20’ All seasons?
I can’t fit 19’ with my big GTS callipers. Cheers

If they are available in 20”, I can recommend Michelin Pilot Sport 4 All Seasons. They have been excellent in Wet and Dry in Seattle.
