Anyone have experience with Diamond Back tires? I’ve been looking at their “Diamond Back III” which is a BFG Radial TA that they customize, including doing just a completely black “smoothie” sidewall. Not cheap at $209 in 205/60R15 but you get a true BFG with which you can then do what you want (Goodyear Blue Streak lettering, larger NASCAR-style billboard lettering, leave blank, etc etc).
