I had new C6R wheels installed at a local goodyear shop and i've been losing pressure in all my tires at a very slow pace. I filled all my tires up to 38 PSI about a month ago and now my tire pressure is 34 PSI in my front right and rear left tires and 30PSI in my front left and rear right tires. My car is driven maybe 4 or 5 days a week. Anybody else have problems with slowly losing tire pressure?

I kind of have that problem with my polished rims. The car had 30 cold pressure when I got it and it's been trending down to 26-27. Just filled them all up yesterday. VERY gradual, so I won't worry about it.

Mine need to be checked every other week at a minimim.

They shouldn't leak! Take them back and have them dunked in the tank. I bet it's the valve stems.

The same store ruined my polished rims when they were taking the tires off so I'm going to take it to the dealership to see what they say. I have filled up my tires 2 times already from the low pressure warning coming up on the DIC.

38psi?? I thought they were supposed to be at 30?

I was driving for about 40 minutes and the temp outside was 100 so I figured 38 PSI warm. Plus I wanted to make sure i wasn't seeing anything and that my pressure has been going down. I could swear the door jambs say 32 PSI cold? Too lazy to go outside and check

I had the same problem on my HRE wheels. As it turned out I pulled one wheel and checked it with water and the valve stems had settled in and needed to have the nut tightened up. That stopped it! Not the valve in the stem but the whole stem / pressure sensor.

slow leaks usually mean that the nut around the valve stem was tightened to much and the washer was crushed...check that

you can get the new washers at Home Depot

mine was just the opposite; I could physically turn the nut with my fingers after the stem seated with the wheels. I
had 2 wheels leaking 1 to 3 pounds per week.
