The good news is that modern tires are much, much better than what your dad and granddad rolled around on. They are far more resistant to puncture.
The bad news is that, good as they are, they are certainly not immune to puncture. Drive enough miles and you will get a flat. When that day comes, it will either be a minor inconvenience lasting about 15 minutes. Or else it will be a painful saga that you'll likely never forget.
Neither choice is right or wrong. But make no mistake... it is a choice.
