If you punctured the wheel, when there is no help. How will you cope with this? In the cayman there is no spare wheel and there is no compressor. If you get into this situation far from the city, it will not be easy for you to cope
Who got in this situation earlier?
In bmw is runflat, in macan - compressor. How to be with 718?)
The goop doesn't do much. Look at Nick Murray's video on it. If you get a flat you're likely calling for a truck.
My R32 back in the day came with a compressor and goop. But then we realized that the Audi TT spare would fit (barely) in the smaller spare spot (the R32 had a shallower cargo area due to the AWD system), so I bought one. If I get a front wheel flat in that car I'm swapping two wheels, since the spare won't clear the front brakes.
