2007 (non touring edition) tires chronically leaking

Hi Folks:

As many of you, my car sits a lot these days, but I try to take it out at least twice a week for a half-hour or so. My tires have developed an issue of leaking chronically. I have goodyear 80k all weather tires which are under warranty. Two days ago they machined the rims and remounted them and the two front tires are already down to 20 and 15 PSI. So I called them back and made an appt for them to do a submerge test on Tuesday and to prepare myself that the wheels might have hairlines cracks. This would not be surprising to me, I can't say that I've babied this car and we have these brutal sharp edged curbs and potholes all over town. The valve stems were replaced last time I had the chronic leak issue.

What are my options for wheel replacement considering I plan to replace this car in a year or two?

 

Well they did the submerge test and they say the wheels are fine, they did something to the bead around the rim and something to the valve stems. I don't know if this is always an issue with Goodyear tires or what, but my partner had almost the identical prius except from 2009 and experienced the same chronic tire leakage

 

They've worked on the tires twice now and say there are no cracks in the wheels, they use the bead sealer. But the Front driver side is still leaking, not all the way to empty like before but still enough that I feel like I can't rely on the car. I don't know what else to do. It gets parked in the garage and we haven't had any salt around here yet.

 

I don't have separate rims for my snow tires and I haven't put the snows on yet. I probably wont since I work from home and can use my partner's Rav4 if needed.
