Just keep in mind that a 50 series tire is fairly low profile and doesn’t have a large sidewall. This may be advantageous for autocross or track but for street use you may find it a bit harsh in addition to requiring 4000 RPMs at Highway cruising speed because of the smaller diameter tire.

Another thing to consider is how hard you’re actually driving this car. Modern tires are exponentially more advanced than what Porsche had access to when these cars were built and much of that may be lost unless you are a very accomplished driver on a track or autocross circuit.

And finally, a big chunky tire makes these cars feel very lively and fun to drive at moderate speeds; something that will disappear with a very high performance low profile tire
