imho, anything larger than a 165 looks pretty awfull on the front.
on the rear however, a 205-65 should tuck in there pretty nicely.
did you get 4 tires? if so, would you consider parting with 2?
*edit* i just noticed you said stock vw rim. what's that? 4\"s or 4.5\"s? i can never remember. that prolly wouldnt work. they would fit better on a 5.5\"or 6\" wide rim.
