I just got 4 new goodyear tires at pep boys. Every 2 weeks, it loses about 5 psi. I bought it back to pep boys and they say that everything seems fine. Does anyone know what could be wrong?

 

Two things to check.

1) Did you get new valve stems with the tires?
2) Have them unmount the tire(s) clean the bead area on the rim & tire(s) and remount them.

 

They shouldn't be leaking that much, something is wrong.

When that happened to me it was the valve stems.

 

how do i check/fix the valve stem?

 

I actually have the same situation with my falkens

 

Spray soapy water around the valve stem, sides and top...Make sure u remove the cap. Then move the stem all around and look for bubbles. If u see bubbles take it back and have the stems replaced..Also you may wanna do the same around the wheel weights, unless they used sticky weights there is a possibility that air is leaking around them and the tire...It happens.

 

^^^ also, you need to put alot of air in to make this work. like 38- 40 lb of air.

 

You are correct, sorry I work 3rd shift and was half asleep already...yeah when I did tires we would put like 50psi in the tires and it would work..
