I'm new to the forum so please forgive me if I'm entering this in the wrong place. LONG story short, after owning the car for two years, I decided to rotate the tires myself. MUCH to my surprise, there is no spare, no jack, no lug wrench and no "green slime kit". What am I missing here? After hours on the internet, it seems my "run on flat" tires are the answer but I'm not happy with that. Does anyone know where I can get a donut spare that would work if needed as a temporary fix. I did buy a jack, lug wrench and a slime flate repair kit but I want some "peace of mind" before I loose my mind.
because MB is trying to save weight and make room for other bits in the car, the cars now come with MOE runflat tires. Personally I think the runflat tires wear poorly and unevenly, make too much noise, weigh more and add no extra sense of security when out driving around and still on a flat tire. Many of the C-class, CLA and GLA owners go with cheaper (and more readily available) non-MOE tires and then you just have to deal with a tow-truck. MB does sell a special order kit for a spare tire, but it takes up a majority of the trunk and is "secured" in place with straps..

AAA membership. Lack of included spare tires are a sad fact of current car life in many cases. Now, not discovering that for 2 years is another story.
I don't even know which is worse...deciding to rotate the tires after 2 years. Or realizing that you don't have a spare 2 years later. Do you have AAA or Roadside Assistance with your insurance? If the answer is yes to either...you're good to go.
Extended Mobility tires are now by-and-large the way of the world - it is not just a Mercedes thing - from the car manufacturer's you do have to design "space for the spare tire" and you ship new cars with 4 wheels/tires and not 4/1/2 incl a mini or 5 incl full size donut spare.
1. Extended Mobility Tires are designed in traffic situations - with dramatic puncture - to allow you to get out-of-traffic to a safe stopping place - so you can then call a Tow Truck - Extended Mobility Tires will not get you anywhere fast or far - same range as a donut with greater speed limitation than a donut really - and frankly Extended Mobility Tires require replacement of that tire if " driven "flat". Yes - the tire manufacturer's are the ones that state a Extended Mobility should not be patched - the tire manufacturer has no way to identify those tires where sidewalls have been damaged by "driving flat" or not sidewall damaged. Same with a repair shop - unless they really/really know you have not driven flat - they may question doing a center tread patch for you because they don't want the liability for you after you drive off.
2. "Standard tiires" which is what I put on 1st week - to me smoother and better driving especially in turns at speed - and target 30K miles of standard tires on my rig - versu my personal estimate of 15K miles for Extended Mobility since they get way/way harsh final 1/3rd of the usable tread. I have a MB jack kit - can of Fix-A-Flat - MB jack kit was quite affordable - Fix-A-Flat cheap (versus MB equivalent more deeply engineered can) - and either way MB Roadside Assistance at hand - and that fresh set of OE Extended Mobility take off's to put back on the car when selling or at lease turn-in.
That's how I wrap my head around it - on a C or GLC investment cost in my standard set is relatively nominal and cheap - it's the S-Class buy's and the bigger E-Class rigs where the investment is much more...
I have a 2017 c300. Stock, base car. Can I put "Standard tires" on my existing rims? Are the rims designed for runflats only? The Michelin site implies that the rims and runflats are a marriage made in heaven and married to each other.
I hope he doesn't have the Sport package on his car, because he shouldn't be rotating the tires in that case!
Forget the sport package, he shouldn't be rotating his tires if he has any wheels besides the base 17" ones. The 18" rims come with 225 up front and 245 in the rear. 19"s come with 225 up front and 255 in the rear. Only the 17"s are 225 all around.
My wife drives a 2017 c-300 with run-flats. Can a doughnut type of spare be comfortably stored in the trunk? Would this be a solution? My recollection is that there is an indentation in the trunk floor but I could be wrong. There are various craft items stored in it now for her upcoming trip so I can't really look without emptying everything. TIA.
I'm not very concerned about a lacking spare because it's been many many years since I've had a flat tire. I'm honestly more worried about breaking a wheel on a pot hole with the OEM buckboard tires. I may decide to carry a can of Fix-a-Flat but want to know more about its effectiveness, and will replace the run-flats with smoother, quieter tires when they wear.
What web site did you find these parts? Is this available in the US?
Thanks
