I received the tires quickly after I ordered them. OEM tires, heavy duty construction. I have about 700 miles on the original tires and have had no issues with them, luckily no flats. Unfortunately I will probably need to replace the original tires with the ones purchased within several hundred additional miles however, the split rims and UTube Rev Rides videos should make tire replacement easy. I suspect a tire with a deeper tread, i.e. off road tires, may increase tire mileage, however it will probably negatively impact range.
