I used GP 5000 TR for years and was happy with them. Two days ago I installed my new GP5000S TR and it leaks air like there is no sealant. :frowning: I am glad I only replaced one tire to check this. I do not know what to do now. I have to pump it before every ride and the next morning it is complet…

I did this. The bubbles come all over the sidewall. They are leaking slowly, so no sound is heard, but it’s all over the side.

[image] Benjamin_Reynolds: I used 30ml of Orange Seal. I use at least 50ml, and if it’s a new tyre, I’ll probably top up another 30ml a couple of weeks later. A lot of the initial sealant gets used up coating the tyre, tape etc. I’d rather carry a little extra weight in sealant than deal with…

[image] splash: I’ll probably top up another 30ml a couple of weeks later. I do this on new tires as well. On tubeless setups, it’s definitely best practice to keep an eye on how much sealant is left in the tires. With a road tire, I don’t really see any need for more than 30ml of sealant a…

Sounds like a flaw in the tire to me. They shouldn’t bubble sealant out the whole sidewall. Like I said above, I’ve only had two tires do that (same brand/model, bought at same time), and both ended up being returned. At most, I get a small number of bubbles on the sidewall that seal off immediat…

If its not the tape or valve, the rim needs to be completely clean IME. Annoyingly I hit a pothole in a paceline a few weeks back and it unseated, a CO2 cannister never re-seated it but cleaning the rim/tyre with some soapy Muc Off bike cleaner allowed my 5000TR to seat instantly with a track pump …

[image] alex_smallet: I did this. The bubbles come all over the sidewall. They are leaking slowly, so no sound is heard, but it’s all over the side. Have a look: [image] GP5000 sidewall leak Equipment Any reason why this would be normal? Mounted up, no sealant to st…

[image] alex_smallet: The manual says I only need 30 ml of sealant. I added a little more. [image] Benjamin_Reynolds: I used 30ml of Orange Seal. I’ve always thought this is fairly normal for tubeless setups though. [image] splash: I use at least 50ml, and if it’s a new tyre, I’ll …

Orange seal recommends 30 to 60 ml (1 to 2 oz) for a road tyre. I have always used 60 ml and so far no leaks.

[image] AlistairSH: They shouldn’t bubble sealant out the whole sidewall. I am sorry about misunderstanding. It’s not sealant, it’s air that bubbles out when I put the tire in the water. I will make a video tomorrow. Today I was riding again and lost half the air in about three hours - from 7…

[image] alex_smallet: I used Continental Revo Sealant :point_up_2: No no no no… No. Treat yourself to some orange seal.
