I have a quick question - I ordered all season 20" spyders, and rather stupidly I can't work out if the Pirelli P Zeros I have on the car are actually all season or not? Is there any way of telling with the P-zeros? If I have summers instead of what I specifically asked for, what would be the possibility of having them changed gratis?


I had the P Zeros on the 4wd Jag X Type I had for 11 years.

They are Summers and not once did I have any difficulty with them on ice or on snow, the Mercs and Beamers were stuck in the snow many times but the Jag always kept going.


I wouldn't even try to drive my old Beamer in the snow, not a prayer. Got it stuck getting off my drive once, gave up and walked to Tesco.

Thanks- yes I'm aware it's a no cost option. I was asking to see if anyone had experience of swopping their tyres and if the cost was different for either option. Yes I could trawl the tyre websites for comparison but thanks anyway.


Hope I didn't appear unhelpful here, certainly didn't mean to. But tyre prices vary day to day, sometimes by quite a lot. The two I mentioned are among the cheapest and usually give good service. Micheldever are also good for Michelins.

This is exactly the problem with four wheel drives, they have the extra traction to get moving but are them even worse at stopping than an ordinary two wheel drive car. Two tones+ on lovely wide summer tires just wants to become a toboggan, and keep on sliding until something like a ditch another car stops it.

Thanks no worries, in my head all weather would more practical but like the look of summer tyres on the rims

According to approved tyres here: http://www.porsche.com/uk/accessoriesandservice/porscheservice/vehicleinformation/tyreapproval/
The only summer tyres in 20" are Michelin Latitude Sport 3 and Pirelli P-Zero (so it sounds like you have summer tyres). All-season tyres in 20" are Michelin Latitude Tour HP and Pirelli Scorpion Tour HP.


I posted this link yesterday Charles and also quoted its content on all seasons this morning. But we must be reading from different documents somehow - mine says the all season Pirellis in 20" are the Scorpion Verde AS.

It is strange - go to the pirelli site and it tells you no suitable All Weather Tyre - find them on blackcircles.com and it says Porsche No (You may need to enter size) Confused

As I found out first lot of snow with my current car - I have a theory that BMW went out of their way to find the worst performing summer tyres on snow so they could sell winter ones
