There is so much BS out there for any tire searches but it feels like it is even worse for this one because of its extremely unconventional size. There is nothing else really that has this size requirement and hence 99% of companies just will not produce it, including Dunlop at this point.
All that being said... Shinko Tires produces a tire that is EXACTLY the same size tire and meets all the requirements for a proper fitment in comparison to the Dunlop. You can also find it for an average price of around $125 (free shipping) from almost EVERYWHERE and it has very good rating by people who are running this on heavy cruisers and touring style bikes.
I'm attaching the information for comparison and future reference, feel free to copy/paste it elsewhere as anyone feels necessary.
This came after the last round of heavy searching, both to hopefully find a good alternative and also to prove my sanity in all of this, and when I stumbled upon it I was skeptical to say the least. However after going over everything with a fine-tooth comb I absolutely feel that this will be the best (and probably only!) replacement for the now extinct Dunlop for our Runes.
I have it on order, along with a few other tires that we already put on order as hail-marys, and we will be checking everything out together once we have everything in hand. Right now I am far more optimistic about getting this resolved having found this tire and I will absolutely keep you all posted on the results.
