Best summer tire for Turbo S ?
 

What are the best summer tires out there these days ? need to get my snows off and need new summer rubber.

I just put on new Dunlop Sport Maxx (295 35 21) tires on my GTS and love them. The price was reasonable ($375 from the TireRack) and I like them better than the Pirelli Pzero Rosso. The Dunlops are quieter, are great in the rain and have great grip (probably not a fair comparison as the Rossos were worn down to near the wear bars, though). What size wheels do you have as I don't recall if the TS came with 20 or 21 inch wheels?

Yokos

In the 295 35 21 size the Yoko ADVAN Sport is about $140 more per tire ($560 more for 4) and not rated any better than the Dunlops but I haven't driven them side by side to have an informed opinion. I just based my selection on the ratings which were equivalent and the price was significantly less for the Dunlops.

Do you have them on both your CGTS and CTT and in what size?

Yes have them on each. Love them. Get a bit noisy after 10k miles though and only last 20k max. Whatever stock size comes with

On my GTS, I've gone through the Yoko Advan Sport and now on the Pirelli Pzero Rosso in 21"....I much prefer the Yokos. They just feel better, handle better, and hell, even look better. I'm taking off my winters this week and it looks like my Rosso's have two tires with definitely more center wear and will have to be replaced soon. Just got a new CayenneS with the 21" Yokos and they are great. I think I'm averaging around 15K miles per set.

I am on the hunt for tires as well.
