spare tire
my 2005 sl500 has a spare tire that would need to be pumped up, which is fine if the 20 year old tire holds air, isn't dry, and the pump also works.
is there any source for a newer spare tire? Anyone make new ones?
Thanks

If you mean wheel and tyre, that's a practical impossibility due to the diameter of the wheel recess. It won't fit. There is no option of replacing the factory spare tyre on the rim, AFAIK.
Best option is to test yours first and see if it still holds air and works. Or be stranded at an awkward moment, like, um, someone...

GLK350 2011 RWD
Sorry that happened to you. Mine GLK is from 2011, and the first time I used my spare tire was a month ago, so actually it is 15 years old and when I took it out it was brand new, ne issues, no seal, nothing odd. I successfully replaced the tire with the factory spare bolts that were in my trunk, and rode about 50 miles before patching and replacing the tire. I actually was often overspending above the allowed spare tire speed 50 mph, and it went fine, so I guess the rubber fatigue is not at all the case and my tire is rather new.
fair point, but i still recommend to have tire plug kit just in case. Last time when I punctured my tire with a screw, I spent 3 days (it was weekend so all the tire shops were closed) and $50 for patching it. Later after watching the videos I realized I could easily plug it myself in 20min, as my puncture was very minor, and could avoid all the hassles of finding the tire shop. Tire plug kit is a must!
I recommend something more sturdy than the standard emergency wrench. I bought this at TireRack, they also have torque wrench. Both are very solid and proven to be very reliable.

Someone said Porsche uses the same product, but don't take my word for it. If you want to be prepared, think about where to put that bigger tire you just replaced with the space saver...

The Porsche flat rear tire drill goes like this: move a front tire to the rear, pump up the spare (if the car has one) and put the spare on the front and the flat rear tire in the passenger seat. I tried that with my daughter's C300 Sport - guess what? The front tire would not/not clear the rear strut - and this was with stock tires and wheels! Lesson learned: plug kit is a great idea!
