ED30:
I am driving with "Goodyear Eagle F1 Asymmetric 3, 225/40R18 92Y XL FP" from the beginning of this summer 2017.
At 7500 miles, I needed to change fronts to back, since there were only 3-4mm left (new tire 7-8mm?).
Rear was ok, 5-6mm left, which is more normal for that mileage. Both sides were close to each other and otherwise equal.
I wont buy same brand again.
I drive about 125 km (77 miles) per day and road is curvy and old, so that might be the reason eating my fronts.
