Years ago my car had a rear flat tire and I was going 70 miles an hour on it without any indication of its condition until a guy pulled along side and pointed to the back end....unless it’s acting squirrelly swerving around ....the difference would be how straight the road is...I was on an expressway without radical turns like driving in town...
Not saying it wouldn’t have sooner or later cut the tire and been on the rim throwing sparks...
Seriously.....
Although I shouldn't be surprised about you not noticing it, I bet you are the type to let your gas get to empty, miss all the warning signs/lights and then wonder why the vehicle won't start.
