2001 Chrysler Sebring alum wheels

[quote]we keep losing a preasure on any tire front or back [quote]

I don't quite understand. Are you losing pressure at one particular wheel, or at random wheels?

When the shop remove the tires, did they replace the valve stems and cores, or did they just re-use the old ones?

Do you see any physical damage to any of the wheels?

thank you again to reply all valve stems have been replaced the probllem is on all 4 tiers could it be the aluminion wheels there is no damage to the wheels but we lose air on all tires often i was told that these wheels could be sandblasted on the inside only what do you recommend

I have heard that aluminum wheels lose tire pressure, though I have yet to see one.

It is a possibility that the tires installed on those wheel are either too wide or too narrow.

These wheels in question.
1. Are they factory wheels or aftermarket? If you have the coupe, the factory wheel is 16"
2. How wide are they? Measurement 16x6.5"
3. What is the tire size that is on them? It should be P205-55/R16.

Wheels can be sandblasted, though for the cost effectiveness, I would rather get a new set of wheel/tire combo. There are plenty websites that offer the combo price and low shipping, rather than trying to fix the leaks (especially all of them) with tires that already have 20K miles on them.
