What is the origin of that SW-S designation - is it the lettering on the tyres?
If so, it is simply the Sideways designation for a wider tyre in soft compound,
eg Prospeed formula, Wide, Soft - one of the tyres I suggested in the other thread.
The "Soft" tyres are 18 shore, same as Slot.it N18, softer than NSR Supergrip which are 22, firmer than Ultra-grip which are 15 or 16 depending on what information you read.
Also a somewhat similar compound to NSR Ultragrip, and have a tendency to ball up unless you true very slowly.
Personally, I prefer to use their Hi-Grip formula, which are easier to true. Both formulations are the same shore ratings for hard, medium and soft. ie 28, 22, 18
