Sorry Casey but, the backstory is nothing near that interesting...
Due to my constant H3 projects, I always have Hummer parts laying around here. So I decided awhile back to re-use stock H3 Duelers on my 99 Burb. After all, many H3 owners install larger MT tires so I run across take-off Duelers all the time (especially spares). They seem to fit my mildly-lifted Burb very nicely. They are a unique size, (285/75/R16) and didn't come on any other vehicles that I'm aware of...and only on early H3's with the Adv. Pak option. Many H3s have un-used ones still bolted to their rear hatch door. So I re-use them as much as possible.
The issue lately is that these 06-09 vintage tires are getting old and they are prone to dry-rotting. I have had two of them come apart on the sidewall in the last six months, both with perfect low-mileage treads. So the sun is setting on the original Bridgestone Duelers, regardless of the mileage. Every once in awhile I find a good one, and when I do...I rotate it into service under my Burb. I have a SAS waiting in the wings along with some BFG 35/12.50/R17s for this truck but, that project keeps getting pushed back for customer H3 projects. So, I'm milking the Dueler supply until I can ditch the IFS and run 35's on 17"s.
