Fat bike wheels and oversized tires create a storage problem that standard hooks can't solve — the J-bend is too narrow, and the tire either won't fit or deforms under its own weight. Park Tool's 470XX is the extra-large machine thread hook in their storage lineup, built specifically to handle the widest wheel and tire combinations. The hook opening measures 125mm (4-7/8") across and 150mm (6") deep inside the J-bend, which gives you enough clearance for tires up to roughly 4.5" wide without squeezing or pinching.

The 470XX uses 2" of M10 x 1.5mm machine threading, which means it mounts through a pre-drilled hole in metal, wood, pallet racking, ceiling structure, or any material you can access from both sides. Two nuts are included — one to set your depth, one to lock the hook in place from the back side. This is not a wood-screw hook, so you need through-hole access. If you're mounting directly into a ceiling joist or wall stud without through access, you want the 471XX wood thread version instead.

The steel hook body is zinc-plated and vinyl-dipped in black, so it won't scratch your rims or tire sidewalls when you hang a wheel. That vinyl coating covers the entire J-bend contact area where your wheel actually rests. The hook carries a 135 lbs weight rating when properly installed, so it handles any single bicycle without concern — including heavy e-bikes and fat bikes that push standard hooks past their comfort zone. If you're setting up a garage, shop, or trailer and need to get oversized wheels off the floor, this is the hook that actually fits them.
