WHERE? are the heavy duty tubes for a 110/90/16 tire

Ok where can I find heavy duty tubes for a 110/90/16 tire. I only see 100/90/16. dc

 

I forget what size I used, but I believe they were from motorcycle superstore. and were't listed as heavy duty. and they have been in the bike for over a year with zero problems.

 

last week the one I got had IRC on the box. It was about $16 or so.
Michelin makes one as well for a few bucks more.

Thanks all I grabbed a few non heavy duty tubes from amazon, I could not FIND many HEAVY DUTY in the 110/90/16 except one that was almost 30 bucks however there were plenty in 100/90/16

 

If it helps in the future try your local Harley Davidson dealer. They should have 16's and 17's available. They are definitely heavy duty.

 

Good idea!!!!!!
