TD has a lot of sizes for 4x108, or any lug pattern just about. 16x8 happens to not be one. With so many sizes, one could easily wonder why not a 16x8 too. Perhaps TD sees all the sizes as plenty enough, I do not know. I get asked for other sizes as well be it Pro Race 1.2 or Pro Race 3. I always forward mentions of 16x8's, so it is not like TD is unaware, especially after the last forum effort. If Europe was asking for them, in my opinion they would have been producing 16x8's already. I never say never and am not hesitant to ask.
