I feel their web page is very misleading stating the spinner will hold up to an 16x10 in the 120 slot. This statement would lead one to believe anything under/smaller than a 16x10 would fit, am I right........... Well, I will have to give Tru Turn a call.
I have a 2.5" standard Tru Turn with an 120 slot, and it fits a APC 15x6 just fine.

Thanks,
