Different Michelin tire dimensions for the same size

Went into pointless analysis mode this morning and figured what the hell, might as well post it here for reference. I was mainly curious about differing tread widths between Tesla-specific Michelin tires & their generic counterpart.

Michelin Primacy MXM4 (TO) - 235/45R18

Michelin Primacy MXM4 (Generic) - 235/45R18 (dunno why two)

Michelin Primacy MXM4 (Honda) - 235/45R18 (probably a minivan? Was surprised at the tread width difference)

Michelin Pilot Sport 4 (TO) - 235/45R18 (sold as part of the 18" summer tire package)

Michelin Pilot Sport 4S (Generic) - 235/45R18 (for comparison to PS4 - generic PS4 doesn't exist in this size)

Michelin Pilot Sport 4S (TO) - 235/35R20

Michelin Pilot Sport 4S (Generic) - 235/35R20

Michelin Pilot Sport 4S (Generic) - 265/35R19 (common aftermarket size)

Surprised that the most you gain in tread depth with the retail tire is 1/32". From memory, I thought most new tires ran 11/32". Must be a reason though.

The T0 version has less curb protection compared to a regular version
