Im losing a lb a week in my tire.ive brought it to major tire place and both times they couldn't find it.i,was wondering could air be leaking slowly from tire monitoring system..thanks
Exactly ^^^^. Do it at home, use the soapy water in spray bottle or even any type of glass cleaner spray will work as well.Don't assume its the valve stem. That slow of a leak is going to be all but impossible to find. I worked in tire stores for years and have run in to the same issue with customers cars. You can try to spray soapy water on and around the stem. It MIGHT, if its leaking, show some bubbles with the weight of the car on it
Thanks alot.im 75 and in high risk covid so trying not to go to stores etc.so if there's a way to tighten it at home in all for it.i have needle nisr so what do I need to do to tighten valve stem.thanksExactly ^^^^. Do it at home, use the soapy water in spray bottle or even any type of glass cleaner spray will work as well.
Soak the tire, valve stem and edges of rim in the spray and watch for any “bubbles”... make sure to move car slightly forward or backward to check the tread area that makes contact with the ground...
You’ll find it...if there is a leak.
The valve stem can be tightened with either small needle nose pliers or the small tool found in a car or bicycle valve stem kit (most auto parts stores should have the kit).
The only other reason tire psi would change is due to exterior weather conditions, such as extreme cold/extreme hot.
You do realize the valve stem is part of the TPMS? So with the short sidewalls, you will have to dismount the tire, mount, and rebalance. Maybe you are underthinking it? ;)No one said assume valve stem, if they check everything and you have a slow leak, replacing the valve stem is an easy and cheap move. You two are overthinking this.
Correct - I should have referenced the word “core” (have since edited that response). The valve stem CORE could be bad or loose which would cause a slow leak.I think he may have been referencing the Shrader valve, better known as the core.
The slime unit worked to tighten the core.thanks alotCorrect - I should have referenced the word “core” (have since edited that response). The valve stem CORE could be bad or loose which would cause a slow leak.
The core tool can be purchased up at any Auto Parts stores (AutoZone, Advance, NAPA or O’Reillys), as well as stores like WalMart.
This is the most common basic tool w/ extra cores:
There’s many YouTube videos showing how to use that tool for tightening up or replacing cores.
