Firstly. A tire review will vary greatly depending on what tires you have moved away from. If you are moving from budget/normal to premium tires your review will always be positive. Premium to another premium brand... maybe not.
I always have used Continental Sports Contact tires on my Saab 9-5 Linear Sport estate (175bhp) and have always been consistently pleased with the results in all catergories.
I was due to have all four tires changed, the first time since the new tire labelling was introduced. Because of this additional information I made a decision to move to the Goodyear Eagle F1 A2's. According to the labelling information the Goodyear is much better fuel economy than the Sports Contact 3s that I had on my car. For me this was the clincher.
Now after several hundred miles here are my findings.
Plus points :Noise level significantly reduced.
Minus points : Handling not as good as the Sports Contact 3, neither is grip, after managing to wheelspin in 2nd gear on a couple of occasions. This never happened with the continentals. The car feels as if it is being held back by something. You can drive on these tires with confidence and I'm trying to give it a few hundred more miles to get used to the tires, but crucially when it comes down to it I'm simply not enjoying the ride.
BIG MINUS POINT: Despite having a higher fuel economy rating I am achieving worse results. On the same journey, with the same fuel and same weather conditions I have noticed a significant reduction of 13mpg. Yes THIRTEEN. That is a huge drop.
(I cannot comment on tire longevity, as I have only been driving with these tires on for 1000 miles)
I am seriously considering moving back to Continental Sports Contact before these Goodyears end of life. The Goodyears have had a negative impact on my driving experience and on my cars performance.
I'm quite annoyed. Had the new tire labelling standards NOT have been in place I would have gone with Continental Sports Contact 3s again, or possibly 5s. Everything about the labelling pointed to the Goodyear being a better tire... but for me, and my car, its not.
