What Did You Do To Gen4 Prius Today

Checked the treads in our 2021 AWD (just went over 30,000 miles) and two of them are in the red and the other are yellow...so shopping for 4-new tires before Colorado winter hits us.
I like the Goodyear Eagle Sport tires at Tire World but, also, like the Arizonian Silver Editions at Discount Tire.
FWIW, even though I have the AWD version, tires on the front wear just about as fast as the non-AWD Prius...so rotating them every 5,000 miles is important.
What tires do ya'll have?

 

Finally got tired enough of the Gen 4 "meep-meep" horn so ordered the Lexus/Land Cruiser from EBay...they had a 10% discount so just over $50 after taxes.
A bit worried...just read someone put one on a Gen 5 and it doesn't work so made sure my seller has an easy return policy. (Part Number 08522-B1010) They are actually hard to find on Toyota sites and, when they have them, around $200....crazy.

 

Presuming you powered from the rear view mirror space rather than run wires to the fuse box. Does it support parking monitor (providing enough power to keep it going if something is sensed to activate?)
