LT225/75R16 We started experiencing very noticeable vibrations when driving at highway speeds. We brought the van to our dealer for service and they responded "Please replace at least both rear tires. Right rear seems to have ruptured internally?" "Please replace that right rear tire asap." We had the tire removed and you can see the attached photo of the inside of the tire where something has obviously failed. These tires only had about 17,000 miles of use. I still have the bad tire.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2018 Ram Promaster (driver Only) verdict →
