Just started riding a bike I haven’t used in a few months, with 26x2.8 WTB Rangers, Caffelatex sealant.
Topped up with 60ml of sealant, rode a while, started slowly losing pressure. Topped up a bit more, took wheel off and swilled it around… still slowly losing pressure. Only the rear, front is OK.
No visible sealant peeking through anywhere.
Bizarrely, I can’t hear or feel any sealant sloshing around inside the voluminous tyre, and there’s no sealant sputtering through the valve when inflating/removing the core. Even though there’s now around 150ml of fresh sealant in there…
What to check next? Please don’t say remove the tyre, these are a bitch to get off the WTB rims…
If you don't remove the tyre, how are you going to replace the valve? When I've had slow non-obvious leaks, it has been where the valve seals to the rim bed.
If your tyres/wheels don't hold air - pump them up and cover with a washing up liquid and water solution. Bubbles will form at the point of leaks, shake wheel around so sealant gets to the leak and hopefully it will seal.
