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

Great price fast shipping, seems to work just as it should

Very heavy duty tube. Should hold up nicely!! One ride on it so far and no issues!!

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.

Works as intended

Super stoked to try out this companys tubes and tires....I heard alot of good reviews on them

Used on a vintage car.

Easy to install and fit perfectly

I inflated mine alittle to check the tube out, one side immediately bubbled out, shouldnt it inflate consistently?

Used it front wheel 2002 FXST. LOOKS OF GOOD QUALITY

I bought this tube and installed it, will honestly say its the thickest tube Ive ever attempted to run. Installed it and everything was great. Took the bike out for a rip down the dirt and felt accomplished as any person would after putting a tube in. Got back and threw the kickstand down then walked away. Started working on another bike and heard a short brief hissing noise. Went back to the bike and the tire was flat yet again. Removed and found a pin hole next to the valve stem. Had to pull a tube from a different bike and its been fine ever sence
