(3) OEM Tire Failures 2015 Trailer Rainier (tredit/goodyear)

I have read alto on tire failures. I keep my tires checked both air and temp. I keep between 60 and 65. What else can I do to prevent tire blow outs? When a tire does blow do you hear it or feel it? I haven't had one yet but I am still new to this yet. Our first trip was 1300 miles to Florida. I had to put 800$ on my truck the P series tired weren't cutting it. I do look at my tires for side bulges and tread damage too...
