Hi,

I made an observation over the past 2 days I have spent driving freshly graded gravel roads in the bush. On both of these days I have had a flat tire caused by rock punctures between the tread of nearly new, quality on/off-road light-truck tires.

Does road grading break the larger stones into sharp points which increase the possibility of flats caused by stones?

Has anyone else noticed this problem or am I just having a bad string of luck?

Mike
