FAQ
Will a 20 x 4.5 tyre fit any 20 inch fat bike?
No. Wheel diameter is only part of fitment; frame and fork clearance matter too.
Can I use a 20 x 4 tube?
Many 20 x 4 fat-bike tubes can work, but confirm the tube size range before fitting.
Is this for ADO bikes?
No. Check the bike's tyre clearance and original tyre size before ordering.
