Why were the ford model T's tires so thin?

Answer 1

The roads in this day were horrible and very few paved roads existed. Most roads were dirt or gravel. The narrow tires mounted on a large 30" wooden wheels provided a very high ground clearance and the narrow tires would get down into the mud to hard ground thus providing good traction. Wide tires did not even exist at this time. The tires and wheels were perfect for the time.
