My dealer managed to get his hands on a set of new tires for my Z. The question I have is, did bridgestone also change the tread pattern on the 17 inch 040s like they did with the 18 inch size. If someone with a late 04 or 05 Z with 17 inch tires please look at their tread pattern and let me know. My dealer has a number of 18 inch but no 17 inch models in stock. The dealer has checked with their so called experts and cant get an answer. They really dont want to install the old tire if there is a new one. Thanks guys
