BFG Truck Tire Problem

[JandC]

My hometown tire guy suggested the BFG Rugged Terrain 275/70/18 tires for my F350. They were rated with plenty of weight, had a decent tread if I needed it for traction, and were quiet on the highway. He knocked a few dollars off and put them on for $212 each.

With right at 30,000 miles on them I was traveling from Florida to Illinois earlier this week pulling a 24' enclosed trailer, not much weight. Left rear BFG developed a raised spot on a section of the inside tread. Stopped at a tire shop in Clarksville and they confirmed it was coming apart. For about 40 miles prior to stopping at tire shop it was "hopping" pretty good.

To make a long story short, Clarksville dealer had a used tire the correct size he mounted/balanced for me ($45.00) to get me the last 400 miles.

My hometown dealer measured tread left on old tire, confirmed separation issue, and replaced the BFG for $95.00.

I didn't think that was too bad of a deal. He said he inspected the other 3 tires and all looked good. According to him they had at least another 15,000 to 20,000 of life left in them.

One side of my brain is telling me that if one started to separate then maybe another one could. The other side of my brain is telling me not to spend $700 dollars if you don't have to.

Thoughts?
