Not just the GT, GTD, GTI but ALL Golf 5 and 6 plus Passat 3C and anything based on these platforms. Some makes of tyre or more susceptible than others. This is VW's official line on the subject.

Customer statement / workshop findings
Saw tooth tyre wear / tyre noise.
A Major cause of annoying tyre / road noise is â€œHeal and Toe wearâ€. This is the outwardly visible (and audible) manifestation of various distortional forces at work on the tread. To explain this, it is better to first say something about â€œtread designâ€.
Tread grooves and sipes â€“ a source of noise â€“ are absolutely essential in ensuring safety on wet and flooded roads. In the case of low profile tyres in particular, a higher percentage of tread void is necessary to take up and channel the water, while a hydrodynamic tread pattern design is needed to ensure water displacement.
The upshot of this is â€œdetached blocksâ€ in the shoulders. Because of how the tyre rolls over the road, the blocks can suffer heel and toe wear under certain operating conditions.
When a tyre rolls, the individual blocks in the tread are deformed.
On entry into the contact patch, the blocks are compressed. In exiting the contact patch, the blocks rub against the road surface and spring back to their original shape, resulting in higher abrasion where the lug tapers off.
This wear pattern is more likely to occur on non powered wheel positions.
If the tyre is driven in compliance with the specific operating conditions, the difference in height between the front and rear edges of the block does not exceed 0.8mm, a level at which no noticeable deterioration in the tyreâ€™s characteristics is to be expected. More conspicuous heel and toe wear points to specific operating conditions (improper inflation pressures, excessive toe in, driving style).
To arrive at an improvement in the tyre wear pattern and a relative reduction in road noise it is imperative that tyre pressures are maintained regularly in accordance with the manufacturers specification. Also rotating the wheels has the effect of evenly distributing wear, so that the tyre returns to its original favourable noise level after a certain distance.
Above all please remember that tyre wear is unavoidable as a frictional force must be present between the tyre and road surface.
This year my VW dealer told me it's because i drive most of my miles alone, (I don't) where the car has been designed to carry two adults (inc driver) and the weight of a small child in the rear!
