I love the way these tires turned out. I am interested in doing the same to a set of tires that I purchased from Diamondback. They sell them now "pre-smoothed". All that they need is the addition of the stick on lettering. Can I ask where you purchased the Goodyear lettering from? Also, would it be possible to get the measurements from you on the lettering? Hight of the letters, and the spacing in between would be very helpful
