Range of 1.4 mm profile for summer soaps

Hey, friends of the four rings! Since it is now high time for the last of us to put on the summer tires, the question arises for me about the profile depth. I stored all four summer tires at the friendly and still 3 mm, 3 mm, 3 mm, 3.5 mm profile on it. Now to my question. I come with it still 6 – 7 months over the laps (running performance about 9000 km). My car has alla wheel drive, that would have to have a positive effect as well, right? Even if only slightly. When the tyres are placed in storage, you can see a note on which it is written that the profile depth of 3 mm (for summer tyres) and 4 mm (for winter tyres) does not fall below. If this is binding, can it happen that the dealer refuses to pull up these tyres again? Finally, 1.6 mm are required by law. What do you think, at what profile depth do you attach new flaps? And one more thing, you can flat-rate the distance within which one millim eter departs – with a humane, non-ripe driving style. (summer and winter tyres). Does the vehicle weight and the hardness of the tire also depend on sure. Drive a Pirelli P 6000. Can you help me? MfG Mimichel
