What dangerous condition can occur if dual wheels (ruedas duales gemelas) on a rear truck axle have unequal tire pressures or mismatched tire diameters?

1. The steering wheel will lock in a left turn
2. The larger or higher-pressure tire carries an excessive, disproportionate share of the axle load, leading to rapid overheating, tread separation, and sudden blowout
3. The fuel gauge will read empty
4. The tachograph will stop recording distance
