I have been caught out by a sharp stone from a car parking area puncturing right through the tread, so I now do it every time. I am probably going to walk around most of the car to get in anyway.
I live at the end of a cul-de-sac, so get quite large vehicles turning around near my car and car parks are always a risk.
Best gadget I have ever had.
Lots of trees around,, which always seem to be either shedding leaves, seeds or blossoms.
I wouldn't check it specifically, but it would be obvious if it were not flush with the bodywork as usual.
