What type of valve stems? Plastic, steel, rubber???
The OP stated the tires failed from tread separation, nothing to do with valve stems???
Yes it can and does.
I personally saw it. I bought 6 new tires and headed out to Houston.
I had a rear blow out.
The tire looked just like a retread gone bad. I too swore it was a bad tire, and was real ticked off about it. But the rest of trip would prove otherwise.
A tire going flat and not caught usually in case of the duals in the rear and driven on doesn't always 'just go flat'. The heat of driving on it separates the tire.
I had 2 more flats on that trip. Thankfully caught while off the road.
The third road side semi tow truck driver caught it. RUBBER valve stems. I was driving in Houston in summer, temp was 112, I was driving real long hours per day. The valve stems where heating up to the point of melting.
New tires and tire store put on rubber valve stems. I could have checked the air pressure in those tires 10 times a day and come up with the correct air, it wasn't going to help tell me when the valve stems would start to fail.
Failed valve stems, loosing air, continue driving on it and the end result will look just like a separated tire. Real sorry I didn't take a picture of it.
