If it's wet, please DON'T do that. That's absolutely the opposite approach to take. If it's wet, run per the tyre placard. If it's dry, I'd argue that way over inflated, you'd be over 50psi after a few laps and driving on the centre of your tyres.
Plus it's happy laps, really not something to get too carried away with. Somewhere between placard recommendation to +4 psi is bang on for most tyres.
