Rubber's?

[Tsal]

Are the B3's a good tire choice for racing on asphalt? And will they fit onto 26's?

The B3 compound is good for outdoor asphalt in warm temperatures. The item 53705 is for the 24mm wheel, and none for the 26mm wheel. The B3 tires are good for TCS, but if you are running in a series that allows you to run any tire, there are better alternatives from MuchMore, Sorex, and RP.
