Slow leak on new installed tires

[Noobto_rescue]

Hello all I just had tire shop mount tires. 2 of the 4 have slow leak where I have to pump in 2-5 psi every 2 days. I only travel 40 -100 miles in 2 days. No punctures I had wheels of covered in soapy water can’t find any bubbles. On tires or valve or bead. I changed the valve stems but where do u think I’m losing air

Take it back and have them screw with it. While 2-5psi isn't a gross, catastrophic leak, it's not a small leak in my opinion. The shop should stand by their work.

I have had a valvestem leak and a bead leak on new tires. Take them back. Not your problem to deal with.

Bring it back, they shouldn't be losing air that quickly. Let them figure out the problem and rectify it.

answer with the limited info provided
"somewhere"

submerge tires in kiddy pool

what type and how old are the wheels?

2-5psi a day is findable that is not a small leak.

Need a dunk tank, I’ve found many slow leaks with mine!

It's most likely valve stem seals on the TPMs. It may be a rim interface thing.
It's a pain to take it back, but either way, they need to fix it right.

Did you spray soap around the valve stem?

 

[Kestas]

Spraying soapy water and a little patience will reveal your leak. The slow leaks show up as fine foaming. I often find this on rims - both steel and aluminum - that have over ten years service in the rust belt. They develop corrosion where the tire seats on the rim. If you're motivated enough do this yourself. Not all shops will have the patience to properly find the leak.

Another tip... try to pour soapy water instead of spraying to keep the amount of initial bubbles down, which can mask the leak.

had this problem with my second purchase ever from Discount tire. the nearest one was 100 mi away from me at the time, near where i used to live, and some friends still lived.
1 tire out of 4 would be down to about 20 psi every couple days. I called, they said bring it in, and we'll look it over.
I make the 100 mi 1 way trip back to their shop, counter jockey tries to blame seasonal Temperature swings, etc., anything really to make it seem like it was all in my head.
I hit him back with " wouldn't that effect all 4 tires, not just this one?" trying not to be "THAT Customer" I even pointed out that I lived 100 mi from their shop, and came there specifically because i had been treated well in the past...

Finally one of the other guys, checked in on what was happening, turned to Counter jockey #1, " Dude, you know we had that Run of bad valve stems, that's probably all it is.. bring it in and replace it."

never had another leak from that tire in the remaining few years i owned that car.

Had this happen on two of the four new tire purchased at Belle Tire, both real slow rim leaks. 1 psi leak every day. They fixed both. Never happened on any other tires I purchased in 35 years.

You paid for new tires and installation. As others have posted, call them up and make an appointment to get the job done correctly.
Good luck.

I had this problem with Cooper Discovery 235/70/17 tires. I installed them October 2015. I had retired and my 2005 F150 sat in the driveway. In the Spring, I noticed one tire was low (right rear) about 20psi. I removed the wheel/tire and checked for a nail/stem with soapy water-nothing. I had other vehicles to drive & ride, so about 3 months later the same tire was low again. Then, I thought the neighbor kids were doing it. I switched the wheel to the left front so I could keep an eye on it. One day, I read on a website that Cooper tires leak at the rim, maybe a bad batch of tires? I picked up a nail (2019) in the "slow leaker" tire, plugged it, replaced the front tires in 2024. I still have a pair on the back, 29,000 miles, and one leaked to 11psi in February 2026 at the rim. I only drive my Pickup around town, about 500 miles a year. I sure do miss cheap recap tires that was available in the 1960's. I still have the original Hankook spare tire. I've used it twice in 21 years. I checked it 2024 and it had 13psi.

Rim leaks are easier to find if you take the wheel off and lay it flat then pour soap water around the gap. But like the others said, take it back to the shop.

The gas industry uses a soap mixture that is quite viscous and will last long enough to show a small leak. We called them fuzz bubbles. A leak with a very small aperture and high pressure will blow soap right off without bubbling. Using a brush will help find small leaks.

Swagelok Liquid Snoop is the industry standard for performing leak checks.

Old chrome wheels? If so especially GM products the bead needs to be smoothed out.

 

[The_Jeff]

When you take it back have them strip the tires off the rims and smooth the rims that way. Don't let them just break the beads and smear sealant goop in; that's butchery.

Rim leak at the bead.

I have the same issue with tires I got at discount tire. They are blaming rim corrosion and refuse to fix it.
