On the first drive today I have been extremely impressed. They are far quieter than the Pirelli P7 tyres that they replace and seem to give much more comfortable ride with bumps being far more smoothed out and less jolts as you are driving.
|Goodyear Efficient Grip Tyre Review|
The tyres on the Passat are quite big being 235/45R17 which can be noisy due to the profile but this seems to be well controlled with the Goodyear Efficient Grip Tyres.
It's too early to tell if there is any different in fuel economy from the tyres but the Goodyear Efficient Grip Tyres are meant to be one of the best rated for low fuel consumption.
