Tires Kumho or OEM Porsche

Tyres: Kumho ecsta lx platinum

I swapped my OEM tires for summer tires (Kumho Ecsta PS31), they provide much more grip and are a bit quieter though since they aren't LRR (Low Rolling Resistance) I do lose about 10% on range.

Go with the Kumhos from Tire Rack. I had really good experience with them

I've used Sumitomo and Kumhos performance summer tires with success - although the Kumho PA31's I put on the Fit have worn super fast and are now quite loud.

Wrapped in Kumho Ecsta V720 tires, have less than 5000 miles on them

Kumho AT51 have been really good. Really quiet, great in winter, but feels like you driving on ice at high speeds (80mph) which is expected from these tires.

I would go for the kumho tires out of those 3, they make some decent tires.

I have the LX Platinums on my GLI. After 20,000+miles, they show little wear. Handling is definitely noticeably worse than the original summer tires, but not awful. Winter traction was surprisingly good.

I had a set of kumho's on my 08 GTI and they were terrible. Very expensive and terrible performance.

I have the Kumhos and I don't like them. They are quiet, and seem to last forever, to my chagrin. Personally, I'd rather trade a little tread life for more performance, but they might be what you are looking for. A word of warning, though: they break loose pretty easily when it's wet.
