2018 Prius Prime - first time for tire replacement!

As a remote worker and now newly retired, I have put just 30k miles on my car in six years! Given that I still have 4/32nds tread, I cannot see why I would want to bother paying for tires rated to go mega miles as I wouldn’t be able to get my money’s worth out of that expenditure. I am considering either replacing the OEM tires - Toyo Nanoenergy A29 or even go with a less expensive Hankook while the Toyota tire sale is still on. Any opinions are welcomed. I don’t expect more mileage in the future as my car is not the road trip car (we own a hybrid Prius as well). Thanks
