so... on my way home yesterday my tire fell off some how. i thought the burning rubber smell was coming from this junker vehicle infront of me i think it went 4 miles like this. but it could have been longer. ZERO change in driving characteristics... rather weird...

what size wheel and tire?

Gramma_Benz

oh crap!


Only thing I can think of is you got a really fast flat or dented the inside lip and lost air?

yeah, those are the only ideas i had too. it was after a left turn also... so it would make sense that a flat or a dent caused it to slip off that direction.

hmm thats not seen too quite often

instant deflat shouldn't dismount the tire tho. I've done that before when i had the HRE and the rear picked up a nail. it shredded the sidewall, but not dismounting it.

that might be caused by the tire never seated properly on the rim by the installer as i've seen a few case.

It's amazing you couldn't feel the difference for 4 miles?!? Glad you got home safely.

Improperly seated or very low tire pressure and a harsh turn.

HOLY CRAP! so was it a failure on the tire or just a bad install?

Your assumption is probably right...you had a flat tire and it broke the bead during your left turn...the sidewalls are so stiff on low profile tires that it would be hard to notice...I take it that you didn't have the TPMS feature...

That's why I find it odd that MBUSA disables the basic TPMS. That was the first thing I turned on with my C55. Really helps with low profile tires and saved me when I got bad valve stems once. Three flats in two days.

whats this?


good news, no further damage, the inner bead was still seated. but the wheel chewed through the sidewall pretty good. no pics today, will take some tomorrow.

It happened to me before when I had 35 series up front on my Bremma wheels. The air pressure was low and when I turned left, it basically ripped the tire off the rim.

TPMS = tire pressure monitoring system. I noticed there is an icon on our dash but thought it just wasn't equipped with it?

cannonball55

I mean,I know what TPMS is. I just meant how do I activate it? and where does it get its reading from? the wheels dont have TPMS sensors in them.

wow... that's crazy

Glad you n ur car is OK.. It could've been a lot worse...
Do check tire pressure once a week.. It's well worth it..
That happened to me in my other car awhile ago... scary ****..

RES

There is one system that works through sensors in each wheel that tell you the pressure in each tire. The other system works through the ABS system to tell you that you have a tire low. It will warn you when one tire is down by 3-4 psi.

Is it possible to turn the TPMS system on with aftermarket wheels on an 06 C55? Sorry if this has been answered before, this is interesting...

lkfoster

You need a STAR machine to activate the function. I never could find a dealer in Phoenix that claimed to know anything about turning it on, I had to use Steve at MBenzNL.

Tire size doesn't matter, it just looks at differences in pulse counts between opposing corners.

RES

I have a Star system and its easy to enable the basic TPMS.

advans

how the hell does that work eric

mikekuriger

that's happens a lot when you have rims too wide for the tire. my audi s4 did that twice because they mounted 225's on a 8.5" rim. I switched to 245's and it never happened again.
