2016-04-13 - Can you please advise me what is the letter d at the end of TZ300d tire.
Two options. The first and most likely is that some tire companies are using the D character instead of the alpha a on their online listing, and it is in fact the TZ300A. The second is that Firestone have released a new version called the TZ300 delta, but we've not been told about this.
