Hmm, I run mine at 35 but when I had my last service done at the dealership they inflated them to 37 and they felt hard as a rock. If I go below 35 the handling feels off. Look here.No. The AS3+ I have been running at that pressure are the stock size 225 40R 18, they have all worn evenly and been rotated per Michelin's requirement. The tire pressure is VW's suggested value for the optional 'summer tire' 92Y load rating tires per the manual.
