GLC300 Spare Tire Options
 

We own a 2017 GLC300. My wife periodically makes long trips cross country to visit family. Distance between viable cities which might have a run-flat tire should she have a flat are well outside the 50 mile limit on the run-flat Perelli tires that come with the vehicle. After our first flat tire at 13,800 miles, we were told that all of the tires on the vehicle needed to be replaced. My wife is a conservative driver so we were very surprised. We talked to our Mercedes dealer and they said that 15 - 17K miles is typical for what you should expect to get out of the Perelli Run-flat tires. I was amazed and am not willing to replace tires every 15K. I set out to purchase regular non-runflat tires, a spare tire and spare tire changing kit. I was shocked to learn that in the USA you cannot purchase a spare tire or spare tire changing kit for the GLC300 (you can purchase these items in Europe). After days of research, I discovered that the spare tire and spare tire changing kit for the 2013 / 2014 GLK 350 fit the 2017 GLC 300. I ended up purchasing high end non-runflat Yokohama tires from Discount tire and I purchased the spare tire and changing kit off of eBay. Everything worked quite well and here are the details:

Nice post. Thanks for the photos. if this were available in the US would buy it in a heartbeat.
how wide is the entire unit? i don't think my underfloor storage is as deep as is shown in the photo; i believe i have read that the area does vary by market

hopefully I can track this option down in Australia.
Thanks again for posting this very useful info. Well done.

I wonder if this compact spare (2014 2015 Mercedes-Benz GLK350 17x6 Spare Wheel Rim Vredestein Tire OEM ( 362079764662) would work for 2016 GLC 300 4matic which has 18" rim?
