Replacing only 1–3 tires creates mismatched wheel speeds, causing Tesla's FSD to interpret the difference as drift and over-correct, resulting in the ping pong effect. Using mismatched tire brands and models creates inconsistent rolling resistance, triggering lateral wobble on autopilot. Tesla recommends matching all four tires by brand, model, and tread depth to prevent these issues. Standard passenger tires are not rated for Tesla's weight and instant torque requirements, potentially contributing to handling problems.
