The tires are older but like new condition. I will post the born on date of the tires tonight. This setup has less than a thousand miles on them and will fit either the Bullog or Mastiff with the 300 rear tires. I am looking for a honest offer. please submit replies thru the pm system. if you need more info or want to talk about it, I will give my cell number to interested parties. thanks for looking. Just added a picture of these wheels on my K9. They will fit but you have to use the mastiff front fender and fender mounts which i have as you can see in the above picture.
