What is an effect of low tire pressure on vehicle handling?

Low tire pressure significantly affects vehicle handling, specifically in terms of returnability—the ability of the steering to return to the center position after a turn. When tires are under-inflated, they have increased rolling resistance and increased flex. This flex can lead to less precise handling, making it harder for the steering system to return to its neutral position after maneuvering, ultimately affecting the driver's control over the vehicle.

In addition to compromised returnability, low tire pressure affects other aspects of handling as well. For instance, the tire's contact patch with the road becomes distorted, which can lead to a loss of traction and stability during cornering. This means the vehicle may not respond as quickly or accurately to steering inputs, leading to a less safe driving experience.

While low tire pressure might offer a slightly softer ride quality due to the increased flex in the tire, it does not improve steering precision. Instead, it detracts from it, creating risks associated with poor handling. Increased wear on tires is also a consequence of low pressure, as the tires operate under conditions that promote uneven wear—particularly along the outer edges.
