Could 10 year tires really be safe?

Next time everyone is out driving. MoHo ,car whatever you drive observe how many tire carcasses you count along the road . New tire, old tires ,Who knows. I once traveled I 45 South from Oklahoma to Houston and counted 18 blown tires along the roadway that day. Summer time is here and people are traveling pulling that old camper ,boat or whatever that has been sitting a while, and I bet tire condition didn't cross anyones mind or the thought is, I can make it this trip. I did and had problems. I will say I am planning a long trip(2200 miles) and tire replacement was going to be done a few months from now. My trip a week or so ago,proved otherwise(500Miles). I needed to replace tires now not later. Yes I have road service ,yes I have insurance, but being stuck on the side of the road increases price of services, and maybe having to accept a product you don't want to get you out of a jam. Then you have to go and pay more$$ to have tires removed and balanced once you get going again. So Lesson Learned: To save a buck cost me more than a buck. Just something to think about.
