Hi
Will standard 5" tires fit on the F27.5W80H28K74? I see 3.8" to 4.6" is recommended above.

Hi Adam
5" would be a bit wide for the F27.5W80H28K74 (74mm internal width). I highly recommend running in below 4.6" as what we presented. I hope this is helpful, let me know if you have any further questions.
Thank you
