Some of these newer alloy wheels are harder to mount. If you let them know there’s a history of leaks on that tire they may apply tar to the rim which can go a long way. My car has had a lot of issues on one tire until I found the right mechanics, ironically they were also the cheapest (small business who specialize in used tires). Later after getting new tires the problem went away without the tar, so I think it comes down to surface prep.
