20x1&3/4 same as 20x1.75 are they the same
-
And if not does it matter will they both fit on same rim araya 7b to be exact
-
NO!!
20 x 1 3/4 or S7s are skinny tyres developed for Schwinn they won't fit on a 7B
What year are your 7Bs Jono? Have you laced them yet as some have large spoke holes for heavy gauge spokes?

1977 they are already laced although I am putting a coaster hub on the rear so will need to replace it hopefully spokes can be re used
-
So are they not 20" or are you saying they not wide enough for the rim I sppreciate 1 3/8 are skinned 1 3/4 should be considerably wider..... No

maybe that means with rims ? oh im confused now. :buck2:

Typically S7s are low profile tyres (these days) but with a wider bead so they're too big for 1.75 rims - 20 x 1 3/4 only fit Schwinn rims

Porkchop sell 20 x 1 3/4 tyres and have this disclaimer:
* Size: 20" X 1 3/4" (IMPORTANT: These only fit Schwinn S-7 rims... they will NOT fit a 20" X 1.75". This is because a S-7 rim has a 419mm bead diameter and a "regular" 20" X 1.75" or 2.125" rim has a 406mm bead diameter. Although mathmatically the number looks the same, in the world of tire sizing, it is a COMPLETELY DIFFERENT SIZED TIRE. However, 20" X 1.75" TUBES are compatible with these tires.)
