If you live in an area like I do, you can change your stroller tires every week. After reading the reviews, I took the tires to a bike shop to have them installed. Between the $40 for installation and the price of the tires, it was a bit of an investment, but I won't have to keep changing my innertubes which would have eventually cost more.

Was fairly easy to replace old tubes. I guess it's better than getting flats all the time on my ebike due to places sending old Chinese tubes dated 20 years ago. You do need a screwdriver and a rum and coke...errrr. Flathead screwdriver to remove and replace. Maybe just needs a little time to get used to it. Time will tell.

I wouldn't use these for my bike, but they're perfect for my bike trailer. Installing these takes some muscle, but now I don't have to worry about getting a flat on my bike trailer.

great for no flat tires

I bought this for a bicycle trailer because even the flat-proof inner tubes and armoured tyres kept getting punctures. I did not use the green goo because the trailer goes indoors and I did not want the mess. It fit perfectly but it was extremely difficult to install, in large part, as it turns out, due to cold weather. Also, they had to be installed very slowly to allow them to flex and relax. The first attempt to install failed because they were too cold and stiff. The second attempt took me 3 hours to install the first one because I was working too fast. I only got it installed through sheer, exhausting persistence. I realised why and I installed the second one very slowly and successfully completed it within an hour. While I would endorse them for use on trailers I am reluctant to do so for bikes because such tubes often come off the rim in turns, and I have no experience at all with using these on bikes.
