Heres a trick I use- Seeping tubeless tires cure! Remove the valve core and let the air out. Fill a ketchup/mustard squeeze squirter, with the small point dispenser tip, with corn oil cooking oil. Squirt about 8oz of corn oil into the tire. Install new valve core, or at least make sure the old one don't leak. Inflate tire to max. pressure on the sidewall. Mow the yard, or do something to roll the tire around for a while. Observaton- Vegetable oil is not harmful to rubber, but it certainly makes things gummy and seals up leaks.
