Question

Quizplus · Accepted Answer

Trailer-specific tires are designed differently from truck tires in several ways: they are often lighter in weight to reduce the overall load, have shallower treads since they don't need to provide traction in the same way drive wheels do, and are constructed to last longer under the specific conditions trailers experience, such as long periods of storage and straight-line travel.
