GLK250 BT Tires


In another thread I posted just last week that I had found a can which appears to be compressed air. Almost all the writing is in German so I can't be sure what it is, except for one spot which says "Tire Sealant". The name on the small tank says "Tirefit".
Anyone have any knowledge or experience with this? Lots of writing in several languages, not English, but the technical words in Portugese, Italian and French are all unknown to me though I can read and understand much in all those languages. But the neat thing is, it's heavy, has the Benz logo on it and it's made in Stugartt!
Guess I make up a "Canadian" kit for my trip! I'm a bit disappointed in this discovery and I'll be curious to see what MBUSA answers to the letter I wrote them.


My tires are Continentals, tires I've always liked. I've had them on other cars, notably an SD300 I also picked up European Delivery. High mileage!
My tires are regular 4X4Contacts. I was looking up the specs and found only one run-flat tire in the Continental lineup, for a BMW in a size way away from my 235X50X19. I looked mine over thoroughly. Maybe that's why my sales guy was so accommodating to me before I went to Europe. The dealer offered to change the tires for me if I didn't like the runflats, at no cost to me after the car arrived here. Naw, they also presumed they were runflats. In some old threads here people were *****ing about them and the ride. That's why I said mine rode nice, they were standard tires and I didn't even know it!! I thanked the dealer when I returned and never thought more about it until I started planning a 3000 mile trip which I expect to take shortly.
I think the issue with my car was that I got the AMG package which has different tires and rims than the other GLK's have, and what the standard package is for the BlueTec's without the AMG package. But it seems to me that if they were partially equipping my USA car as the Canadian cars without the runflats, that they could have at least given me a compressor with the Benz logo on it! (Actually, I have a compressor as I posted in another recent thread, but it doesn't have the tri star on it.) I like the size and storability of the Benz compressor so I may push to get one, not that it really matters to me.


I think I know what happened on mine. I had ordered mine some months ahead of the build date. At that time I had to order a sunroof, which I had no use for, but it wasn't possible to get other options I wanted without the sunroof. A week before the build my sales guy called me to tell me they would would build without a sunroof and give me the credit. I jumped on it. I think the Canadian specs always allowed that option and I'll bet mine was going to be Canadian and it got mixed up in the process of the several changes immediately before and after mine was built. I'm guessing that's why I got half of the special equipment (no compressor.) They offered to put runflats on there as well. They have been super nice and show Mercedes Benz class!
Thanks MBUSA and Mercedes Benz of Rocklin!!!

We just got our 2014 and it does not come with the cable. Dealer says it connects somewhere down under front of engine, but there is a cover there, so I couldn't see anything.
I did ask in a separate thread, but no answers

If there's anything more on this side, THAT would be the block heater!
On the other side it's impossible to attach. . . . . .

A mirror and a flashlight should lead the way!!

I also checked for the block heater. There is none. Only thing missing of what I was supposed to have, is the runflats. Mercedes insisted I had both runflats AND compressor and sealant. I've asked for an emergency spare and hope I can get that instead of the runflats!
Logic of buying them is still a bit fuzzy
If we have a flat with our MO tires, I suppose first thing we will try and pump it enough to get on our way to somewhere we could have it checked. Or if in a bad spot, we would call roadside assistance. Only time I could see us using compact spare, would be if flat would not hold air and roadside assistance preferred to put spare on rather than tow us. There could also be times when somehow roadside assistance is not available within reasonable time frame.
A full size spare with replica rim would have been cheaper and more useful. But finding a place for it in/on the GLK was a challenge. The compact spare should tuck in behind the passenger seat when we are on road trips and maybe give us a little peace of mind ??
of tire sealant. Everything I've read says not to use the stuff on wheels with tire
pressure monitors. If you use the sealant and the tire pressure monitor dies will MB
replace it, for free?


I wouldn't use it if I had a flat in my driveway or very near a repair facility. But if I had a flat on US Highway 50, 'the loneliest road in the America', there are only 3 settlements over about 500 miles of desert, I'd use any means at my disposal to get me out of there, particularly in the summertime where temperatures will exceed 100!
In reading the tire section of the manual, the only tire allowed for the GLK250, is the MOExtended all weaher, which is the semi runflat tire that US delivered cars get. All others including the 235/70-19 99H M+S that Canadians get, have a note 17 alongside, which says "USA: Not for GLK 250 Bluetec"
So why would All Weather tires be OK for Canada with no spare while US gets MOExtended?
By the way, many owners use 17" rims with snow tires. In fact they are recommended for the GLK350. According to manual, those too are not suitable for the GLK250BT!

How about the other issue. How to install winter tires on a GLK250 if you live in USA? The owner's manual doesn't provide an option for that!
It rules out what most are doing here. 17" rims with 235/60-17 winter tires. Manual say not to do this, but only in USA! Maybe due to lack of spare or runflat capability?


I have a 2014 GLK250BT (dec2013 build delivered jan014 by a Boston MB dealer)
The Lack of spare tire was stuff to take - (like my two previous BMWs that had Run-flats its nerve-wrecking when you drive in country-side with little no cell coverage's)
due to my work requirements - thus the smaller Diesel engine!
I quickly tracked down a MB dealer willing to sell me a Vredestein (from GLK350) and it sits in luggage area in a plastic bag with a 12V compressor from Walmart + Guus. Orders on line = NO SALES TAX (pls msg me and I can send the vendor info if needed)
In my humble experience - MBUSA & Canada either don't know their customer's requirement(s) and are WAY TO ARRAGONT to listen to their concerns!! My last two cars that had RUN_FLATS both had flats that could not be REPAIRED BY THE DEALER - and good for me as I had '4 yr tyre insurance' ,,,, and am sure that cost them heaps. 4 tyres with side-wall damage due to driving in GRAVEL Roads after puncture -rendered those tyres USELESS with RIMS !!!
FYI - the same GLKS in rest of the world are given a Vredestein spare tire!
