Tires Pirelli or Falken

I'm running 255/40-17 RT615s on 17x8 ET35. This is on a "regular" MK4, not an R32. It should not be an issue, the additional grip provided over 225/235 is noticeable.

225/40/18 falken ze512's on an 18x8.5" wheel - and those are correctly sized for the mk4 - rolled shoulder extreme...

Falkens are a good tire choice for the price.

I just put these on as summer tires and auto-x tires and the traction after they warm up a little bit is awesome. I used to have trouble even with the F1s spinning in second sometimes. With these I get pretty zero under hard acceleration.

I run my 615r for my daily and on auto cross. One HELL of a tire. The wet grip is amazing. The dry grip is even better. I have yet to break them loose in an autox event. There are gobbs and gobbs of grip. Plus the tread is meaty from the get go.

I have a set on one of my Corrados and LOVE them. I've only had them for about 3000 miles so far, but dry grip/handling is amazing, and wet grip really isn't too bad at all. Standing water I would take it a bit slow, but even on a wet road after the rain, they grip/handle pretty well.

I rolled the rt-615 and loved them, More grip than I ever needed/used.

Good luck with yours. I've driven more on mine, and after adjusting my suspension, I am loving them. Good traction at any temperature.

The Pirelli PZero Nero M&S is a ULTRA PERFORMANCE tire [one step down from the MAX PERFORMANCE] and is an all-season tire, which is a compromise in handling compared to the Kumho MX's.

Same as driving the F1's in the snow. Maybe even a bit worse. Don't even think about it.
