Can anyone tell me the difference between these 3:
215/45R17 ZR GOODYEAR EXCELLENCE XL
215/45R17 91Y GOODYEAR EAGLE F1 GSD3 XL
215/45R17 87V GOODYEAR EXCELLENCE MO
I have the Eagle F1's at the moment but they're rated ZR not 91Y.Which is the best to go for?

For a Newage you want a 92Y , W or Z rated GSD3.
The others are a different tread pattern and designed for less sporting cars.
