The Sorex Tires are marked on the sidewalls. You have to look real close to see the numbers on it. You might want to check what inserts you have for them. I am still looking for the rates for the Ray Speed springs. If anyone knows them can they post them for me.
RaySpeed springs: soft to hard
RS yellow = AE Silver 14.5 lbs/in
RS white = my guestimate around 15.75 lbs/in.
RS red = AE Blue 17.0 lgs/in
RS grey = my gestimate AE gold 19.50 lbs/in.
