My daughter delivers Mail for Post Office and she drives 150 miles a day most on lime stone roads these tires last about 9 months before she starts having flats any other tires last about 1 month then starts having flats 1 a week for the next month then daily after that.
Delivering mail is in rural Maine is brutal on my tires. I can now do my 108 mile loop with less stress. My husband swears by BF Goodrich. I'm glad I listened!
