The spring set your are talking about sounds like OP-440 On-raod Tuned Hard spring set
This is a set of Red,Yelow,Blue,and White
These also at one time came in all white with the dabs of color so you know what the spring were. These are a little bit taller. Anyway you most likely have springs all ready and i use a many different springs and tires so i cant give you any advise as it would just be silly to try and guess a good tires for you.Im glad the other guys all ready helped you out.
