New Rim and Tire leaking air !!HELP!!

Just got a set of new wheels and tires last Monday.
I installed my oem Tpms sensors in them. My front driver side wheel is leaking air. I fill it up and I drive it the whole day,the next day I get in it and the tpms light is on and I check the pressure and it's about 20psi. I took it back to the shop and we looked for leaks and we couldn't find anything. We thought it could be the tpms seals so we replaced them but it still didn't fix it.
The rims and tires are brand new so I don't know what it could be.

Please post any comments or suggestions.

Thanks

Take some soapy water and spray the whole wheel with it. You will see bubbles from your leak. Be sure to spray the whole barrel and tire tread. It's easiest when the wheel is off the car.

I already did that twice I submerged the whole wheel in water and still nothing

How long did you hold it under water for? I like the soap method because you can let it sit and inspect closely. But if youre losing 15psi/day, youve got quite a decent leak.

Yup, it should be pretty obvious after re-inflating and spraying with soapy water.

The above advice is assuming that the leak is prevalent when there is no weight on the tire...I had a similar very slow leak after changing my OEM rims for some Alufelgen wheels. Every week I had to put air into the tire and dunking it gave no indication of location. But put weight on the tire and it leaked about 10psi a week. Breaking the bead my shop found sand particles in the bead...cleaned it up and no issues since. Maybe something to consider.

^^Good advice Rick. Never thought of that.


I was also gonna say check out your valve stem nuts. They require VERY little torque. Like 5Nm (I think), those 11mm nuts can back off and cause a slow leak. Its very common for these rigid TPMS valve stems to loosen up and leak.

Just use a 11mm deep 1/4 socket and snug them up. IF you over tighten them(or IF your shop did) you will break the valve stem and need to dismount the tire to replace the valve stem.

I'm at the shop where I bought the tires and they are checking them out as I'm writing this post.

Did they unmount and remount the wheel? I would start with that.

I would contact the place you bought the wheels from and ask for a replacement set of wheels. Or just the wheel that is leaking.

Rim might be bent. Did they put new valve stem on it?
