That's not true. The correct answer is on the door placard.
What you have tried to calculate is a tire load. I'll wager you divided curb weight + passenger/cargo by 4. That gives you the wrong answer.
And that's only static tire load... what's the tire load at speed? When cornering? When braking? On rough roads? You want an estimate of peak load on any single tire.
Then add a safety margin for things like tire pressure, ambient temperature, vehicle speed, etc.
The correct answer is still on the door placard. Ignore it at your peril.
