How to reduce tire traction

[Zeta]

I want to drift my low hp grandpa’s car, so i’m wondering if i can achieve less traction on the rear wheels. I was thinking of changing the tire pressure. But i’m not sure if i should go for more or less psi. Does anyone know how to make your tires more slippery?
