Is it normal for a brand new car to come with 2022 tyres?

I have received my brand new proton x70 2025 a month ago but the ride is very bad and harsh. It’s bouncing even at normal road.

Sent to service centre for 6-7 times but can’t identify the problem. SC keep denied by saying it’s “normal”.

Today I found out that my rear tyres are without manufacture date and only has a printed “2022” there.

Is it normal for new car to fit with such old tyres? Would it be one of the cause that make the car behave bouncing and uncomfortable ride?

Giti Savero SUV.

I have the executive specs

Tried 220 230 240.
Problem still persist.
SC is helpless
Not sure how to make some noise to have their attention
