VW use the following manufacturers tyres on Golf GTI's.
Continental.
Bridgestone.
Dunlop.
Michelin.
It's luck of the draw.
There is much forum debate on which is best or worst but a lot of is quoted on the basis of magazine tyre test results rather than personal experience.
Don't worry about the Dunlop's, they are a fine tyre and unless you are Gavan Kershaw or Sebastian Loeb then you really won't notice the subtle differences between respective brands.
Although I expect like everyone else on here (including me) you'll claim that due to your extraordinarily well honed driving skills that you need the ultimate everyday road tyre to extract maximum feel with minimal sidewall flex on your way to Asda.
