What is the term used when the rear tires are closer together than at the front?

The term used when the rear tires are closer together than the front tires is known as "toe-in." This alignment condition refers specifically to the angle of the tires relative to the centerline of the vehicle when viewed from above. When the back of the tires points inward toward the vehicle’s centerline, it is described as toe-in. This alignment can enhance vehicle stability and straight-line tracking.

In contrast, the term "toe-out" would refer to a scenario where the front of the tires is closer together than the rear, which is the opposite of what is being asked. "Camber" relates to the vertical angle of the tires when viewed from the front; it can either lean inward (negative camber) or outward (positive camber) but does not pertain to the spacing between the tires. "Tire-wear" refers to the condition of the tire surface and does not describe the wheel alignment itself.

Understanding these terms is important for diagnosing alignment issues and ensuring proper handling and tire wear on a vehicle.
