have a 2018 GT, w/ stock Falken tires w/ about 15K on it. about 3 months ago i went around a corner (a little fast) the tpms light came on. turns out the right front tire pressure was low. it's come on twice since then. i've had the tire check and can't find any issues (nails / cuts / etc ). Could it be the seal between the rim & tire? I have the extended tire/rim warranty, would that be covered?
