Had our first major tire issue

Based on all of the threads I have read here, I had already come to the conclusion that we would replace our FW tires prior to our trip to Colorado in September even though our FW is only a year old. Unfortunately, we will need to replace sooner as after our arrival home from our trip this weekend we noticed one tire was low. We had checked all tires before the trip and all tires before coming home...all had adequate pressure. We to thought perhaps we ran over something along the way so we took the tire off to get repaired but found out it was not repairable. The belt separated and the tire has a bubble. I am just sitting here being very thankful that we did not have a blowout. That would have been a good way to ruin a trip. Now, time for the real decision...what to buy? I believe I will be looking back through all the tire threads (well maybe not ALL of them) and doing some tire research. I sure wish I would have gotten a few more months in first. Oh well...price we pay for our passions in life.
