What causes my Wagon R to feel unstable o r shaky at high speed despite correct tire pressure?

Even though I regularly check and maintain the correct tire pressure as per the manual, my 2019 Wagon R feels unstable o r wobbly at speeds above 80 km/h. Could it be related to uneven tire pressure distribution, alignment, o r wheel balancing?

Even with proper tire pressure, instability at speed may be caused by:

Uneven pressure between front and rear tires: Always follow the car’s recommended PSI for front and rear, which may differ.

Wheel imbalance: Unbalanced wheels cause vibrations, especially above 70–80 km/h.

Out-of-alignment wheels: Misalignment causes pulling, uneven wear, and poor stability.

Tire defects: A warped o r deformed tire like a bubble o r belt separation can cause shakes.

Fix:

Balance all four tires.

Get a wheel alignment done if you haven’t in the past 6 months.

Inspect tires for bulges o r flat spots.

Use a reliable pressure gauge and inflate tires according to driver’s door sticker o r owner’s manual.
