Tires, being your only contacts with the tarmac, are absolutely the most important components on the whole automotive system. Without them, you can’t move & control your vehicle. And when you can’t control, you & your vehicle becomes with a road hazard to others around you. This is downright irresponsible to other road users & your family (since you are endangering yourself as well)
Hence, always sadden me when I see such irresponsible drivers / riders on the road. Just look at the worn-out tires! Besides, this is a huge commercial truck, it would be disastrous in event of mishaps due to tires.
