My C4 has the ford gas,works great. People said it would be had on gas, but I can move 38 tons of wood on 8 gallons. I was looking for a diesel,but this C4 was owned by an elderly gentleman for the past 20 years, and only used for his own firewood. I can't say for sure on the tire, a friend got a nearly new one for his 230 for $1000.
