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

Update 4/27/23 - these people decided to hide my original review. I hate shady businesses. I got the tube in the mail fairly quickly. Got my bike broken down and the tire off, pulled the old tube out and installed the new tube out of the box. When I get the tire all put back together and on the bike, I realize the inner valve stem was bent (Straight out of the box). Made for a pain in the ass because the parts stores are a long ways from my house and on a Sunday everything is closed. It would be nice if they could send me a replacement valve stem.

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

As described, heavy duty tube. I have used several tire products of the ProTeaz line and have been pleased.

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.

Nice Thick tube

Bought these for spare and to bring them along for ‘ just in case’ hopefully I never have to use them, received these inner tube very quickly and seem very sturdy,

Great value and so far holding up well to the abuse with lower tire pressures.

Will buy from again

Tube didnt hold air out of the box
