Everyone here is right and everyone is wrong. The three top end dealers are Goodyear, Michelin and Pirelli and they are marketed that way. You also have Dunlop, Yokahama and Bridgestone which are middle of the road, and Falken, Kelly and Kumho which are bargain tires.
Every company makes good tires and every company makes crap tires.
Some are unfairly crap because they are used in a manner other than their design and have poor performance ( ie. Eagle F1's in the snow). If you are rating the OE tires that came on your car you are judging middle of the road tires that the auto co. got in bulk to work for the masses not the individual enthusiest.
If you run all season tires which most of you have mentioned you are getting average performance of everything and exceptional nothing so don't expect it!
**One last word of advice - Your tires are the single best saftey feature you have on your car. If they don't stick you don't go, you don't stop you don't have control. All from something that is mearly held to your car buy air! Think about that the next time your looking for the cheapest tire you can get!
