Maybe instead she'd be happier being the one putting air in the leaking tire for the next 50,000 miles.
A wheelbarrow or something works too.
The bead can be submerged a portion at a time by laying the tire flat on the ground, filling the bead area with water, and then tilting the tire just a bit to have a portion of the bead area be the low spot and submerged while you look for bubbles in that spot.
Or just add air to it once a month, and if the leak gets worse (probably nine months from now during winter) then do an actual fix.
If the OP doesn't have a bead breaker or wouldn't want to patch a nail puncture himself, etc, then figuring out where it's leaking from is kind of a moot point because his two choices then are either live with it or bring it to a shop.
