What are the original tire specs for the upgraded tires on the TT 3.2 Roadster 18" wheels 9 spoke
My reference shows an optional factory tire for your year on the 225 and 250hp models... 225/40ZR18... The 225 and 250 hp had different load ratings though 92Y was the highest 88Y the lowest. However, the tire size and rating should be on the old ones... If you can't find the rating and don't know if you have the 225hp or the 250hp then I suggest just getting the better tire to be safe.
mine runs on 225/40/r18 92y pirelli P-zero Rosso they came one it when new and when they wore out i replaced them with the same. you can get away with a 235/30/r19 but the ride becomes really harsh. 18's or 17's are the best way to go
