I'm one of those who hates owning a car without a spare even with Porsche assist, most of my Audi's and Mercs didn't have one, I said I'd never buy another car without as spare, so I buy a Macan without one....
. Over the years I've built up a collection of puncture repair kits with cords that push into punctures as a temporary repair. I still don't like having no spare and even worse Porsche rely on a decent mobile phone signal for owners to contact Porsche Assistance where other prestige brands use GPS hmmmmm. This morning I decided to purchase the collapsable spare with relevant, fastener, tools and jack(they fit under the floor) to be gobsmacked that when configuring a Macan the spare is available for £200ish but purchased later it's £400ish so with all the tools it came to £555ish, wow. Rather than hunt around for the different bits and end up with something that isn't right or causes damage I decided to bite the bullet and go with Porsche at least I know it's all the right kit. It's worth the peace of mind after all these years when miles away from home worrying about the hassle of punctures with no spare even with assistance services, no more worry thank goodness, all I have to do is change the wheel myself if assistance is hours away. Oh well that's my introduction over, apologies for the rambling fellow macanforums member .... 
Then how long will you want to be driving around on that 18" spare. Me, I will wait for Porsche recovery, even if that should inconviennience me for a while. I have had a nail puncture, but it remained inflated while I drove at low speed to my nearest tyre centre.
