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

Only had it on my bike for a month and certainly hadn’t been riding a ton. Came out one morning and tire was completely flat. When we pulled it off found this split in the tube. NOT HAPPY

Put on Suzuki savage front was impressed with thickness made spooning tire easer due to not pinching. They also include a valve stem removal cap. I would buy again if needed.

They hold up OK. Not the greatest but for the price its good. I had recently bought one. Im almost positive it had a hole in it when it was delivered but I cant prove it because I had already installed it in the tire before I aired it up.

When I aired it up to seat the bead and then let air out I was like WTF? I did this tube swap in my living room because it was cold in the garage. Living room stank for an hour. Tube seems good but man what a stink.

worked as it should

Was just installed, durability is still to be rated in time.

This tire is very good. Second one I have had on my DR350. It works perfectly for adventure biking and reliable in the woods/dirt.great tire

I used it for my motorcycle bike. It was easy to install it looks great. Thank you

Replaced front tube in my 1990 DR250S with 90/90-21 front tire. Excellent quality.

Great value fits great love it
