2 new Rim T sizes and E17.25

We’ve expanded the T series rims to cover 17 to 17.75 making the profile available to a lot more players.  The design is a moderately cushioned traditional peak and has been successful with those who tried it so we’re expanding it out to cover common sizes.  We might even consider a T18 if there’s enough interest.

E17.25 is also now available for those who prefer smaller rims (who also tend to be einsetzen players).
