Is it just me or does everyone have problems w/ blowouts? I tow w/ a '95 Tahoe and have had different tire brands but the result is always the same - they never just pick up a nail and go flat - they have catastophic tread separation while pulling my car down the highway at 75. Just had one Sun. , a 60,000-mile Dunlop Rover w/ 25,000 on it literally disintegrated. Scary. Same w/ trailer tires. I have never had that happen on any car I've ever owned. What gives?
