2001 Impala. Driver’s side front and Passenger side rear tyres go from 35psi to 15psi in a span of 2 weeks. the other two tyres will go from 35psi to 25psi in 3 weeks time. I am assuming bad valve stems as the tyres are brand new (bought it that way) this issue will be addressed in Spring or Summer. But what should i tell the shop? The stems should not be bad as they are suppose to be replaced with new ones upon changing the tyre. Also the spare tyre was totally flat. it is a Compact Spare. on the sticker on truck that states tyre pressure for spare is 60psi my question is a donut spare is good only for 50 miles at speeds no faster than 50MPH so how come you need to get a whole new tyre and rim for a new spare? how come you cant just mount a new tyre on the donut rim?

most liking its the tire stem or the valve, and the “donut” tire is only for use in emergencies, not for everyday use. i dont think u have to get a whole new rim but if the tire goes flat then u might need a new tire.

by looks of the spare it was never used or touched for 13 years. the Valve Stem Cover was never removed i had to take a wrench to it to even break it loose to check the tyre. I had to add a Valve Stem extender to it to even air it up. even completely flat it was hard as a rock and bounced like a kickball.
if i were u, i would take it to a tire shop and have them replace all 4 tire stems, since ur tires are “brand new” they shouldn’t be leaking, also get a rag and some water and soap in a bowl and wipe the whole sidewall of the tire near the rim to see if u have any leaks around the bead. if there is then u either need to remove the residue from inside the rim where the bead sits. here’s a good vid: https://www.youtube.com/watch?v=8hOZXIr1ujE

as i stated below ill take the car to the shop in spring or summer whichever is warmer 1st. being dead set in winter with single digit temps and windchills between -5 to -35 below using water to test for leaks probably a bad idea. I have no idea how old the tyres are got the car in August 2009 and they were new then still have the nubbens that new tyres have.
If you have aluminum wheels then it’s likely that they are corroded in the same way as you see in the above video. I had to refill my tires about every other week for the same problem because of the leaks around the rim. If you spray soapy water in the suspected area of the leak it can show you where the source is.

I have no idea what kinda rims they are they look like this:
rims should of been cleaned when new tyres were installed.
[quote=”EricTheCarGuy” post=49135]Those are aluminum or ‘alloy’ wheels.[/quote]
dunno what that means
