What issue might arise from tires that touch each other?

When tires contact each other, it can lead to potential tire damage, making option B the correct choice. This contact can cause the tires to wear unevenly or become damaged, which can ultimately compromise their integrity and performance. Tires are engineered to operate individually at the correct pressures and alignments; when they touch, it can result in increased friction, overheating, and even bursting. This damage not only reduces the lifespan of the tires but can also impact the safety of the vehicle.

The other choices do not accurately reflect the consequences of tires touching each other. Increased traction would not occur since the tires are not able to maintain optimal contact with the road. Instead of improving fuel consumption, potential tire damage could lead to decreased efficiency and increased fuel use. Furthermore, braking performance could be reduced rather than enhanced, as damaged tires can lead to less effective braking and increased stopping distances.
