Currently we do not offer a hook option that is compatible with fat bike tire sizes. The long hook option found here will work with plus sized tires up to 2.8 width. Depending on what rim/tire combo you have, the printed size on a tire can vary from the actual tire size based on side knobs and internal rim width dimensions. It’s best to measure your actual tire width when inflated on your rim to ensure the long hook will fit your plus sized combo, but if you’d like a second opinion, please feel free to email us.
