My tire says 2 ply sidewall. I did bump it another 1/2 today & firmed up the shock 5 clicks Monday. Felt good today. I hate to say it, but the only ill effect I've really noticed is it's easier to stand it up off the side stand now. Otherwise I'm greatly impressed!

I was one of those guys. Of course, on my HD I was getting 20k from tires, so no incentive to go DS. I honestly expected low speed handling issues, but there's been none really noticeable.
