Set of 2 Flat Free Tire Assemblies 13x5.00-6 Compatible With B1WL58 TCA13769 TCA 13769 D38009

I was disappointed to find that the grease fittings appear to have been an after thought. Tires arrived together in the same box. I did a quick inspection of the tires upon arrival and discovered that the grease fittings were loose. I attempted to tighten the fitting into the hole, but the holes must not have been drilled or tapped correctly since the fitting would just start to tighten and then loosen again until the fitting dropped past the threads. At this point I had to stop to prevent the fitting from falling all the way into the hole. This was the case on both tires.I can't give a recommendation to those who want to just put these tires on, grease them, and go.
