suitable with 2" tires but some small sections are sandy, I needed to push 4-5 times between Bulawayo and Gwanda but on very short sections, max 100m. Some very short rocky stretches too. Crossed maybe 5 cars in about 100 km but you'll find small hamlets every 5-10 km. Shops in Matopos, Silobi, Dula as well the hamlet in between the last two.
