Nissan Pathfinder transmission failure due to mixing tire types leading to mismatched sizes and tread wear on Nissan Pathfinder

Some Nissan Pathfinder owners report experiencing transmission failure due to mixing different tire types, brands, or sizes, particularly in 4x4 models. This issue arises because the rolling diameter of new tires often differs from that of used ones, causing undue stress on the drivetrain and potentially leading to parts breaking. Additionally, mismatched tires can disrupt vehicle harmony, negatively impacting safety and performance, especially in terms of road grip. Owners also express safety concerns, as mixing tire brands can create uneven grip distribution between front and rear tires, increasing the risk of instability during emergency maneuvers like sudden braking or sharp turns. It is generally advised against using a mixed or mismatched set of tires unless specified by the manufacturer, as this practice can severely affect the vehicle's performance and safety.
