This discussion reminds me of the problems Goodyear was having with their G614 tires back in the 2009-2010 time frame. There were those who were adamant that they were blowing right and left and pointed to a lengthy Escapees discussion on the project. So I took up the project and examined that discussion and here's what I found:
"I did research the G614 and they are having problems with blow outs, there is a very long thread on the escapees forum. The good thing is Goodyear stands behind their tires and pays for the damage. I would rather avoid the damage. I did a check on that long Excapees post -- 20 pages, 286 posts ( I may have missed a couple), 9 individual posters had problems with the G614s, some multiple, 5 did not have problems. So while it appears as a long post on the problems with G614s there were not that many individuals reporting problems. Some of the posts were reporting problems on 15 and 16 inch E rated tires. The rest of the posts discussed the problems that could cause blowouts and tread separation, the benefits of different brands, etc. There was even a poster who had problems with a 17.5. I don't deny that there have been problems with the G614s but I would consider replacing mine with another set when it comes time. I have the G614s with a build date of early 05 (don't remember exact date) on my Cameo with over 33,000 miles and haven't had any problems. In fact I had a nail in one of mine that didn't penetrate the steel tread -- it was bent over. To be safe that tire is now my spare. And yes -- I'm bored today."
I am tempted to do the same with this discussion but it will take some time.
Upon an initial review I noticed one poster with many problems was talking about chassis/cab models which have a different power rating, 300/660 instead of the 400/800. Do the chassis cabs have a different turbo?
