Not my Bee but Gary T's. His son "Little Gary" just sent me a text (Big Gary is driving his Bee now) with his tire and wheel info:

Fronts are 15x4.5 wheels with 215/75R 15 tires.

Rear: 15x8 wheels with 4.25 back spacing, tires 29x12.5

(but I did get my Y4 A12 RM21 Road Runner in a roundabout way from GaryT who bought it from the second owner in the early '90's. Second owner bought it in 1971 from a used car lot in Youngstown, Ohio. The name of the used car lot that had the ROAD RUNNER was named..........wait for it.........................it's a ROAD RUNNER .................the used car lot was named ACME MOTORS no lie

(note the mistake of RAOAD RUNNER on the '71 title )
