16" Back and 12.5" (2+1) Front Wheel Replacement Inner Tubes and Tires | Compatible with BoB Stroller Tire Revolution SE/Pro/Flex/SU/Ironman - Made from BPA/Latex Free Premium Quality Butyl Rubber

I have bought this product twice now and will continue to tell everyone how great it is. It’s durable, great price, comfortable and overall I am beyond impressed. Highly recommend

Fits our Baby Trend stroller perfectly!

Fit my babytrend stroller perfectly. Easy to install

Probably not the best quality but super convenient and affordable, I literally got them the next day

Got a stroller for free from a neighbor because a tire was flat. These tubes fixed that easy enough. $200 stroller for $12!

Perfect for BOB strollers. Used this to replace the original tubing in all 3 tires. Been great ever since. Perfect fit.

Quick delivery, packaged nice

These are listed as being "4x thicker than other brands" which led me to purchase them. Since they don't seem to mention their actual thickness anywhere in the product description I purchased them along with another brand that was a couple dollars more expensive but was listed as a heavy duty tube with thickness specified to compare them to and figured I'd return the one that seemed lower quality. Both products were shipped from Amazon in the same box and it was almost laughable when I saw the difference and how much higher quality the other brand was. Since I can't cut them open and measure thickness I am assuming that a heavier product would be representative of a thicker product since they're made out of the same materials and tires are the same size. The failed 16" tube I removed was nothing special so I'd assume it is a fairly standard cheap tube that weighed in at 4.1 oz. The new 16" tube I decided to actually use weighed in at 10.8 oz. and the entire package of three tubes I purchased from Calplay (that I chose not to open and weigh individually since I realized I would not want to actually use them) weighed in at 12.2 oz. for two 16" and one 12" tubes in the package. As a best guess that would likely put the 16" tubes at about 4.5 oz. each and the 12" tubes at about 3.2 oz. It's definitely nothing heavy duty or substantially more robust than a standard tire tube and is downright sad compared to the new tube I went with that was about the same price but more than twice the weight (thickness) of these. Since I immediately returned them I can't comment on actual durability or longevity however it looks like they are no more durable than any other standard off the shelf tire. I am rating them as one star since they seem to be hyping their product as a premium tire when it is actually a standard tire. They could have saved me the trouble of buying and returning it by just saying it was a standard tube and not promoting it as an especially heavy duty premium product.
