Need tire help...
I woke up this morning to a flat rear tire. I went on tire rack to order a new one and wanted to make sure I ordered exactly what I have on the car.
Here is what I got off the rear tire...
Pirelli PZero Rosso 285/35 ZR 18 97Y ('04 SL55)
On tire rack, it had Y Rated and W Rated. Which is it? What does the 97Y mean? Also, our tires are the PZero Rosso Asimmetrico?
Thanks very much, I appreciate it!

I cant remember what those last numbers are, but I think that is the load rating. The letter at the end is the speed rating. W and Y will be fine as the car is limited to 250, and they are both over that speed.
