I had gone to every place imaginable looking for the T300 Step Pins. I could only acquire seven pairs from Omni Models, and Nitro Hobbies. After going into a Panther tire purchasing frenzy, I contacted Panther and asked the team there if they were going to discontinue the Step Pins ST tread since every online hobby shop is out of them. They got back to me with just one little statement...."None of our tires are going to be discontinued. ".

Sweetness!
