Why should tire inspection get extra attention on a loaded tank vehicle compared to an empty one?

Pick an answer

1. Only the steer tires need checking on a loaded tank vehicle
2. Tire condition matters exactly the same regardless of whether the vehicle is loaded or completely empty, since tires are rated for their maximum capacity either way
3. The concentrated weight of the liquid cargo puts more load and heat stress on the tires, making a weak tire more likely to fail
4. Tank vehicles use special tires that never need inspection
