Rotate or get new tires

[milaosays]

Hi, thanks in advance on input.

I have 2022 Model Y. Headed into summer months in Socal, don't expect rain for next 5 months usually.
I have been very neglectful in tire rotation. Currently at 39K miles.

Front tires tread is around 6-7 while back is around 4-5.

Should I rotate, move back tires up front. Or just get new tires?

thanks again.
