GLK250BT: NO Spare Tire; Only Run-Flats!
- MB supplies the Vredstein collapsible spare as standard equipment on other vehicles including the GLK350.
- Unlike some 4WDs, apparently MB AWD can cope with mismatched tires.
- The Vredstein inflates to about same diameter as the standard tires.
For a full size spare, I think it would be possible to make a hitch mounted carrier. I have thought about adding a mounting plate to vertical tube of our bike rack, so spare wheel would be between tube and tailgate. But behind driver's seat works for us when we are fully packed.

To get home safely & having the time to sort options instead of being at the mercy of limited options on the Moab.
Safe return of a Family member is a large positive.
Tire Rack (info partner ) is a good source for tires & further info of specification that are important to the buyer.Price is a factor with run flat tires ,(since there is an added expense for MO,PAX, run-flat tires.)
As mentioned ,every month there seems to be further selection of tire choices.
In the future,a plan probably will be looked into before travel plans.
Many good ideas about solutions is a positive.

I imagine many US GLK250s will in time have AW tires (as they already do if they install snow tires) A pump, some sealant and a compact spare may also be needed.
The Best of Mercedes & AMG




The only issue is I thought I had run flats. Had already made deal with the dealer to replace when the car got over here having heard all the complaints about ride quality and all. Put 3000 miles on it in Europe and I considered it acceptable and stayed with what I thought was run flats. Discovered it wasn't during a discussion here, and I screamed. MBUSA gave me a Vredestein space saver because of the error so I have the best of both worlds now. Unfortunately the space saver was defective when I had a tire problem in the middle of nowhere. Thread on that here as well. But all worked out fine and I'm happy!
I have had the GLK250BT for a year , & my trusted tire dealer continues to look out for me for a run flat tire of various makes that is reasonable price wise since 4 will be replaced.Basically I have no complaints about my Dunlop's but as the replacement is looming ,I will need to bit the bullet with their replacement. " Right now, live with it, rotate my tires & avoid the potholes everywhere from the NORTHEAST Weather....
RANTING

Mercedes Benz decision to outfit the GLK250BT with a tire with a shorter life..
is Mercedes Benz Logic ..." if you own a Mercedes ,the owner has big pockets of cash"
As yet, to my knowledge ,an all seasons 235/50R19 is a size in limited production in a run flat .
My tire supplier is also my repair facility , they inspect & rotate my tires .
My experience with the MB Dealer has not been a positive one & I use factory trained mechanics other than the dealer.
If a recall occurs ,then the MB Dealer will be used...
I fill my own MB with the correct DEF from smaller bottles , the dealer charges the big bucks from the large drum measured out & charged $18 quarts.
If I had a shop , I could buy a large container of PEAK DEF (5 gallons) & save money but I don't have a shop set-up...
Now we might have so many available because they are so useless here and they are frequently replaced by folks who think it should be possible to drive an AWD SUV (well yeah, cute ute) in the snow. Silly us.
So instead of $316 each at Tire Rack for new, here you can get tires with a claimed 50+% of life for around $60-70. After factoring in wear, that is still about a 60% savings.
Or you might just give up on run flats and carry a couple of spare cans of your favorite "fix a flat". I also added the MB pump for $70 from the dealer. I'll probably buy the cans of MB sealant too should I decide to take a trip.


NAPA has smaller containers, believe they are 2 liter. You don't need a shop to store one, or its leftovers, for later use. It runs $14.
However we take trips where we are often 300 miles from the nearest tire dealer not counting that we'd have to wait several days for the tire to get shipped. I'm sure our Canadian friends can significantly trump my number.
Dealers should carry a small inventory of replacement tires for run flat equipped vehicles. But since they cost money dealers would rather just order them. My dealer did provide me with a loaner C class. I guess that was cheaper than a tire inventory.


My story is in an old thread here. If interested see post #37 in this old thread:
https://mbworld.org/forums/glk-class...-2010-a-2.html
No fun driving 500 miles or so on an inflatable spare!!
The sensors will give me a read out of the particular tire effected status.
The tire dealer says the use of the canned tire seal on a run flat tire is not a good idea but he also said in the middle of nowhere , a driver does not wish to be stranded, the future may bring later surprises .
If at all possible ,it is good to salvage the tire , a small nail hole plugged can get the driver to repair shop that handles run flat tire repairs -that can remove the tire ,seal from the inside...make it safe.It is an acceptable way .
A side-wall puncture is a "no save" Running a run flat tire a extended distance is a "no save" hopefully a tire dealer is close to replace the tire.."Luck"
Any replacement of a run flat tire is expensive & the stranded motorist is prey
for the dishonest repair shop,tire dealer, or greedy Mercedes Dealer.
There is much advice out there & I have found situations of ethical fair deals on repairs.
In my research on the future purchase of a new set of tires for my MB GLK 250 , I have realized the wide variety of answers....this forum provides advice in experiences...stories
Solving problems on the road varies , if you have panic passenger experts & little time to think, at best decisions are "fuzzy logic".
I try to stay calm , get as far off the road,out of harms way ...look at the tire & solve the problem. ..if your lucky ,the problem can be solved. I have gotten flats in the past & I never wish for another flat...I have AAA but I still need a tire.
I try to avoid any tow, roll back , or what tow company sends out,personnel /tow vehicle...damage is another problem.


Stop leak makes it almost impossible to reliably repair the tire if it were repairable at all. All it will do is give you a few more miles of driving.

With the tire sensors , the driver in now in the danger zone.
I enjoy the stories from Canada where MB GLK 250BT have a space for the special Mercedes Benz tire sealant & the air compressor. My USA sourced GLK 250 BT has an empty space for both the sealant & the air compressor , my service manuals talk about these items in other than USA Vehicles.
Canadian still do not have room for a full spare & may carry a 17 inch compact spare.The tires are not run flat MOE and a better selection of the best tires for winter(severe weather) are needed. The story of changing tire sets between seasons in Colorado is necessary because Dunlop Grandtrek MOE do not have the necessary traction. All seasons tire is three seasons tire.
Still with all the stories read, stop leak still is "SAID by SOME" the only a quick fix for a tread located puncture.. ,a side wall puncture is a no fix...need a tow or a new tire if it can even to brought to the vehicle by road service.A credit card comes in handy or Cash on Delivery..there might be CLUB like REACT or an local with a kind heart that will help you out....maybe...MOTORING in my MERCEDES is a Adventure.

We are at 56K miles and on our 2nd set of Dunlop Grandtrek OEM run-flats for our GLK250. We have had nothing but good results, but in preparation for our third set of tires I'm wondering what other GLK250B owners have done. The two options I've read about are changing the diameter slightly (to 245 tires), which sets the speedometer off about 2%, or adding a slime product to non-run-flats, which endangers the TPMS I fear. I guess a third option is to buy 5 non-run-flats and keep one at home or (on long trips) in the rear cargo area, which would considerably diminish its capacity.
Does Dunlop still have a monopoly on the run-flats in our size? Are there any other options I've not considered?

I just put a set of Michellin Premier LTX on my 350 at the dealership for less than a grand and they have a 65k mile warranty. (I did have a 15% off coupon.)
Ask yourself how many flats you have had in the last decade and if you really need run flats. Could you get by with a 12v tire pump and a bottle of sealant that you may never need?

We bought a Vredestein compact spare (Used, likely off wrecked 350) On long trips with just two of us, it tucks in behind the driver's seat. Otherwise it is in cargo area or left in garage when we are in easy range of quick MB or CAA service. Never used and a bit of a pain to carry around.
When our tires need replacing, hoping to install all-weather (not all-season) tires that are classified as snow tires and needed in some provinces in Canada.
