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

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

Fit just like it was supposed to. Seems durable. Pinched it pretty good at install. Was worried I put a hole in it. Nope thank goodness it was as thick as it is.

The Pivotrax brand keeps coming out with better and better products. Ive used quite a few of their products and to be honest I am quite impressed, they hold up well to major abuse, very resistant to rock punctures. The perfect extra item for the just incase instances helps as well.

Used on a vintage car.

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.

Seems to be a very good tube for the price. It is 3mm thick vs standard 1.6mm

Will buy from again

Great fit, no complaints.

Heavy duty
