In the quest of increasing the space in my front trunk to integrate an oil cooler, I came across this piece of information that I thought was worth sharing.

Mercedes has been using Vredestein Space Master 165-15 collapsible spares on their smaller models like the C230 and the SLK.

After looking at the pictures and comparing them to my 911 space saver on steel wheel, I think they are the exact same tires.

The difference is that it is mounted on a 4.5" alloy wheel, not 5.5" like the Porsche.

So, one though to gain trunk space would be to mount the space saver tire on a ~$100 4.5" Fachs from cip1. Lighter and narrower wheel, win win. The goal would still to have it laying flat for impact absorption, yet probably allowing a lower trunk floor and giving room for the front mounted cooler to vent out.

Now the challenge is finding a place that will want to remove the collapsible Space Master tire and mount it on the Fachs... (IMG:style_emoticons/default/dry.gif)

Below is the MBZ space saver wheel/tire.

Currently have both in hand, 911 5.5" steel rim with space saver and 986/996 skinny spare. I am studying my options as to ways fit a cooler in there yet minimize the body cutting. (IMG:style_emoticons/default/idea.gif)

Good point Mark that inflated would definitely help more the absorption. (IMG:style_emoticons/default/dry.gif)

McMark's U shape ducting with flat collapsible spare in between is probably the most elegant option as recently seen in PMB Coatchwerks' orange car, but clearly involving and cutting...

Trying to see what is the simplest way as my fabrication capabilities and my house garage operation are somewhat limited (IMG:style_emoticons/default/biggrin.gif).

Thank you for sharing your thought... (IMG:style_emoticons/default/beerchug.gif)
