OK Rip posted some car nerd stuff so I have to match him.
I was waiting for my OEM Bridgestone family sedan tires to wear out so I could do a Plus-1 upgrade along with an Eibach kit and a Stoptech kit. I jacked the car up to do some work and realized the Bridgestones were finally toast. But I am currently short of cash (paying off credit card debt), so I decided to just go for some high performance rubber in the stock size, and do all the other work later.
I wanted a non-directional tire because I need to rotate from side to side (too many freeway ramp skidpad runs). The P-Zero Nero was about the only tire in the "max performance" class that wasn't unidirectional, so I bought them. I had read some very good test results for these tires but they really surprised me. I did my 60 mile twisty mountain run twice over the weekend and it goes quietly through corners that used to make the Bridgestones howl. I made a tire pressure adjustment and the car is now also much more neutral than with the Bridgestones. I haven't driven the Neros in the rain yet, but in the dry these are great tires, and not terribly expensive either.
