Why does 225/50 R18 pressure vary?
Even though many cars share the 225/50 R18 tyre size, the recommended pressure depends on:
- Vehicle Weight: A heavier car needs more air pressure to support its mass and maintain the tyre's shape.
- Load: Carrying passengers or luggage significantly increases the required pressure on the rear tyres.
- Handling: Manufacturers tune tyre pressure to achieve specific steering response and comfort levels.
