I'm a little late to the party but right before I went full-time in the summer of 2014 I replaced all 6 Michelins on my 2008 PC2100 as they were 7 years old and everyone said I should. Unfortunately there was a Michelin recall around that time and they were hard to find. The local tire shop sold those TransForce tires to me hard, telling me they were just as good as the Michelins and cheaper. Without the month wait. So I got them. Two and a half years later (Dec 2016) I replaced the two fronts with Michelins as the Firestones were almost bald. I replaced the back four Firestones in January after one of them blew. The place I had do the fronts only had two in stock at the time and I was leaving for Quartzsite. I didn't think the rear duals were in as bad shape. Apparently I was wrong. Thank god for Coach-Net. The mobile tire guy said something to the effect of, well these tires are pretty old when I was complaining about what crappy tires they were. I said, "They're less than three years old!!!!" He said, "There is no way. They must have sold you old tires." I said, "No, I checked the codes....check the codes!" He did and whistled. My PC was not overloaded, I weigh it pretty often, and I run TPMS so the pressures are good. I put less than 40,000 miles on them. Needless to say, I won't be making that expensive mistake again.
