I had a maxxis minion last 8 years or something ridiculous. It was a rear, but I was impressed! It was also on a hardtail, so in reality, how in contact with the ground was it ever really.Big reason why I still have 5 year old Maxxis that have probably dry rotted to 120 durometer.
The other being if you don't ride, they don't wear out. Saving myself money here.
