I must have a very slow leak on my rear right tire as it has been dropping about 4 psi cold pressure every 7 days or so for the past 3 weeks. I looked for an imbedded nail but could not see one but then again it's kind of hard to inspect it thoroughly.

I want to take it to a tire shop to have it inspected but my car has CL wheels. Do I have to take it to a dealer? There is a large national chain tire shop near my work which is very convenient for me. Shouldn't they all pretty much be able to deal with CL wheels? Any advice would be appreciated.

 

Give the convenient tire shop a call and ask them.

 

Get the car/tire off the ground & spray the tire tread & valve etc w/soapy water and if there's a leak it will bubble up.

If it's in the tread (vs sidewall) it can be plugged w/o removing the wheel.
