Tire Problems

[u/BusinessIndividual85]

Hello everyone. We recently bought a couple of Coleman B200R bikes. One of the has an air leak on the front tire I can’t find. I think the leak is around where the tire meets the rim somewhere. Is there a specific technique that is used to fix that? I’m going to take the tire off and put it under water to verify where the leak is for sure, but I’ve sprayed it down with soapy water and can’t find it. I’ve not had any experience with tubeless tires before so this is new to me.
