Michelin PA4 are available in those sizes, there are N rated and non N rated fronts but only non N rated rears

Not all Porsche summer wheels take Porsche N rated winter tyres (which is why they sell the winter wheel and tyre packages). As you have a relatively new car I would check that your wheels can take both. The Tequipment area on the Porsche website gives you both wheel and tyre dimensions so you can easily see if your wheels can do both and what tyre sizes are.

If not already, have a look in the Owners Manual … mine lists Winter tyres for the Summer wheels as well as a different size Winter set … pp Keith`s note
