Howo light truck 4 100 Chaochai tire problem

Haowochao diesel engine 12 tons, 195 chassis 825 all-steel tires, the trouble is that the fuel consumption is a little higher than others, it is difficult to pull heavy goods, the fuel consumption is not high, and it is difficult to get on the bus. I suggest you buy one with a reversing radar. The broadband radar on the car body is safe and I hope to use it.
