(3-Pack)16 x 1.75/2.15 Back and 12.5 x 1.75/2.15 Front Wheel Replacement Inner Tubes for BoB Stroller Tire Tube Revolution SE/Pro/Flex/SU/Ironman - Made from BPA/Latex Free Butyl Rubber

Both large inner tubes popped under normal pressure the first time they were used. The holes in the inner tubes were were in different places and the wheel and tire did not have any issues that would have caused them to pop. These are obviously poorly made, I should have know what to expect when there was zero English on the original packaging. Spend a few more dollars and buy from someone in the US or a local bike shop if possible.

I got these the other day because I needed them and they were 1 day shipping. Upon arrival, they look used!! Theres so much dust or calcium or whatever on them, they dont look new at all! I used one because I needed it and had no time left, but I would look elsewhere if I were you!

Fast and excellent product

Once installed and inflated to 30 PSA....all look good for about 10 minutes, after that front(small) completely deflated. There is an air leak next to valve. Spend little extra and get a better quality.

Tube lasted about 2 weeks. Replaced it with a new one and that one went flat in a few days. Returned. Don’t waste your time or money.

Product as described. Works as intended. Seller quick postage.

As I was installing the new tubes I put air in first to make sure they would hold air and two of them had holes already in them. Very disappointing and unsatisfied that they arrived in this condition.

It worked and was not too expensive. Cant comment on longevity since I only installed a few weeks ago.

Just the right size

I can’t rate longetivity as I just installed the inner tubes.
