I have issue in one of my tires in my 1997 c280 ,I have a leak,every 3/4 weeks I need to put air,my local guy told me this is very well known in MB and BMW with chrome wheels,it loses the sealant,after checking the tire he couldnt find any leaks,then took the rim out and showed me the sealant that falling apart,then he put some stuff around the rim and put my tire back on,told me theres no guaranty how long it will last,
my question to you MB owners,is this normal?did this ever happened to anyone? is there another solution?

thanks

 

i put air in my tires every month as general maintence. ...or do you mean 3 to 4 times a week you put air in the tires.

 

no, every 3/4 weeks ,sometimes it gets to 20 PSI

 

it must be an aftermarket wheel rim.

i didn't know that MB do the chrome type yet.

 

I dont think these are aftermarket,person who owned the car before , said they were original,

I dont have a close up picture yet

I had chromies on my BMW and never had this problem. I also never heard any talk of it on BMW forums. The good news is you are only losing a few pounds per week. Check it every weekend.

 

yes, it's original alright.

it's an aluminum disk wheel.

they must have it chromed on some factory.

it looks good.
it will look more better if the side strip is chromed together with door handle and trunk lid grip trim.

 

previous owner was a 50 year old woman doctor,

I saw when he was working on my rim,he showed me where the sealant was coming off,and took the rest away before putting new stuff on it,anyway my local guy is from Sears, he charged me $18 after working on the rim for 90 mins, didnt think he was trying to rip me off, so far its good,not leaking.

 

$18 seems right after 90min of service... I paid around there to have them fix mine... Anyhow, that chrome issue is true.. happened to me a year ago.. I guess the chrome gets corroded when the previous owner putused tire sealant to fix his flat...My tire specialist told me that the tire sealant chemical over time ate the chrome! So for those chrome wheel guys out there.. don't use that tire sealant.. use your spare!

 

i have some multi piece wheels and one of mine does that...every week i m putting air in one wheel only from what i been told these wheels have the issues of leaking air... other issues i have seen is a leaky stem which could cause air issues too
