I have an older popular brand of heavy duty garden cart with pneumatic tires. I had problems keeping them inflated within a year, and by year 5 I had resorted to tire sealant to keep them from losing pressure for a day.
I notice that this popular brand now sells a cart with an equivalent rating with flat-free tires. Since I am apparently incapable of (or unwilling to put in the effort) maintaining these tires, I wonder what the implications of running this type of tire on a cart with a rating of 1200+lbs is.
Will mobility or stability be severely impacted?
