AR-PRO 2.75/3.00-21 Off Road Motorcycle Replacement Inner Tube (2-Pack) TR4 Staight Valve Stem - Made from Heavy Duty, 3mm Thick Premium Rubber

Great quality for the price point. This pack of 2 is a must have. No complaints!

Very bad quality

They arrived in a plastic bag. Not sure how smart that was. I installed the first one, it had a hole in it. Did my installation cause it? Probably. Installed the second, same results. I can't blame the tubes though, but they are thin compared to the Kenda Tuff tubes I normally run. Installed a new Kenda tube. and finally got it right. I never got the chance to try either of them though, but I'm sure your results will be better.

Tubes seem of good quality, fairly heavy rubber, 1 tube leaked but I beleive that was my fault installing, the 2 pack is a good plan

These tubes have held up for 8000 miles in my Dual sport. I have done both long distance road trips and long distance rough dirt/rocky rides with these tubes. I have had some tubes that are thicker than these but these seem to be doing really well. I put baby powder in when installing the tube and have a rim lock. So far no flats with these tubes. I keep them usually aired into the 18psi range but when on the longer road trips i go up to about 22 to 25 psi. I have aired down to 15 when in soft sand. Another motorcycle i have i keep them aired up to about 40 psi. No issues either way.
