I bought a 3/4" x 24" breaker bar (4" longer than typical) and 12" extension on-line and have them in-hand.

I have 1/2" drive of both 22mm and 7/8" sockets and tried both on the lug nuts. The true size is 7/8". Though the 22mm fits, it is near zero-clearance. Any imperfection from surface rust or any slight deformation and the 22mm could never slip over the nut. The 7/8" is just right.

So I will be purchasing a 3/4" x 7/8" deep impact socket.
