Tires Pirelli or NITTO

I went with the Pirelli. I'm in Seattle, and had a chance to push them in the recent rain. Great traction in the wet, reasonable traction in dry, low road noise and reasonable comfort at 39/37psi. Very pleased with the tires.

I have the Pirelli P Zero Nero All seasons, and live in Wisconsin. I still have dedicated snow tires, but am happy with the all seasons.

Replaced the factory Conti's with less than 20k on them with the Pirelli P7's and I can report they are a better tire. Road noise is reduced, handling in snow and rain improved.

I autocrossed my car in the Houston SCCA, NGS class back in early June 2015. Car did great, and I have a non PP car. I'm gonna be upgrading to ECS red stuff pads, and stainless steel brake lines for next months autocross. The only complaints I have are the crappy stock Pirelli P7 tires but I will upgrade them when its time to replace those.

I've been AutoX-ing my MkVII this year as well. Nothing too serious though, just more for the fun of getting out and tearing around in the car and meeting lots of great people. I went with tires/wheels this season rather than a tune as many others have, not only to stay in GS, but also because the stock Pirelli P7s just didn't cut it, even for street driving, it would only be worse with more power. I went with a nice easy package from Tirerack on some wheels that were 5lbs lighter per corner and I couldn't pass up on the closeout pricing for the Direzza ZIIs. I only wish I had done it sooner! The added grip really did transform the car, turn-in is so much crisper, and most of the time you can really get the car to go where you want to put it. Rotation is greatly improved too, I'm continuously amazed at how well this car rotates for a heavy FWD.

Neo Gens are awesome when it comes to stretch.

I'm running Pirelli PZero Corsa System and enjoy them

I haven't had any issues with vibration, but have noticed more road noise on my Pirellis after 20 K. Probably won't get another set.

That said, if you're not looking for a performance tire but a quiet, smooth, comfortable tire that holds air and hates to change direction the Cinturato P7s are for you. If you want to drive your GTI like it's a sporty car with some fun and enthusiasm, you'll find that the P7s spin, lose traction, squeal, hate to change direction chatter on braking and generally suck when driving with more vigor than an 80 year old, blind coot who doesn't want to spill his beer.

The PP p zeros don't last very long under any driving conditions, and they are expensive. There are a lot of cheaper summer tires that'll last as long or longer, look at the hankook ventus v12
