PIVOTRAX 90/90-21 or 80/100-21 (3.00 X 21) Heavy Duty Motorcycle Tube - 3mm Thick - TR4

Tube didnt hold air out of the box

Works

worked as it should

There tunes. They work.

Delivery was great. Overall I’m very happy with them.

I had the entire tube installed in my tire…..when i went to go put air into the tire and tube. The stem popped right off. Not very durable.

Muy Bueno

Great value for a thick tube. Received in 2 days. Got it installed, and have 3 rides at 10 psi with no problems. Thumbs up!

Looks like nice quality, have not used or installed, bought as a backup, when needed. Would buy again.

Seemed like a decent tube put it on my enduro. 3 days later driving 45mph and notice that I smell burning rubber, pull over and the tube is completely melted. Had the psi at spec 18 psi. No reason the tube should melt and destroy my tire and rim. Find something else this product should be banned.
