Help with spare tire fitment ( 5 Bolt) Options

[burton73]

I have the early 911 16" space saver spare. There's paranoia out there that the rubber is old and unsafe. I inflated mine and it worked fine, but curious if you can replace the rubber.

I never thought of that. My 86 Carrera has a space saver but I do not know what the size is. I would not worry if the rubber is bad as if you use it would not be for that long. If old rubber on spares from the 80s or 90s go bad there are a lot of people in trouble, as I do not know of anyone that changes out there space saver. You are only to use your spare for a very short time and at slow speed. When I had a blow out on my Carrera on a tire that looked new but was 15 years old, I changed out the tires but still call for a flat bed truck. That is what AAA is for. We may get into a big conversation on what is too old for tires.

Strange, i never had an issue fitting a 16x6 with a real tire on it. I made sure to do a smaller aspect ratio and width. I can check to see what size I used.

edit:
It is 195/50/16, total diameter is 23.5"

A spacesaver set I have for the 356, still with spacesaver tires is:
165/15, total diameter 19.75" deflated.

I agree, AAA is what is used for if I ever got a flat these days anyway.
Going with a front cooler on my /6 conversion will make a front spare not happen anyway.

I think it was 185/?/16

I found this from an old post from a guy that used to post a lot. That is what Eric is doing with #41 my 6

My spare 16x6" wheel that fits w/o issue (front or back) is 195/50/16, total diameter is 23.5"

A 951 spacesaver set I have for the 356, still with spacesaver tires mounted are:
165/15, total diameter 19.75" deflated.

It looks like the space savers are for 15” wheels I can not find any for 16” The trick when mounting then is you have to fill them up with air until l they expand and then let the air out. They stay in the extended position and after the tire people mount them you hit the center of the tread with a bat hard and the tire springs back down. There must be some steel inside to make it spring out. Sounds weird but I got the tip from someone on this board a long time ago. There must be 17s but 15 is what is on older cars.

I opted for a Boxster spare, and although I don't recall the actual size, it's narrow enough so that it fits with no issues. It'll probably never be used, but if so, only for whatever brief period needed, so appearance isn't an issue. Plus it's considerably less weight (and cost) than the typical 911 SpaceSaver spare.

[JmuRiz]

Bingo, a boxster/996 spare is a great option. I think there are some 993/964/968 spares in 16" too. Best to get one of the above since they are alumn wheels.

My 951 15" are alumn too and VERY light!

Coloradocurt: What's the overall diameter of that wheel/tire combo. It may be small enough to mount flat on the floor and put a cooler and wheel-well exit shroud in-front and around it!

OK here is the pictures of my 16 inch spare. 16 x 5 1/2 alloy rim with a 165/70 16 tire. 965.362.130.00 part number on rim. Fully inflated it is the same as the stock spare tire only with 16 rim.

I can sell my 15in Fuchs for the spare for $300. and also sell the perfect factory inflator for $400. Get the Boxster spare for $200. And pocket the $500. And have less mess in the trunk.

Thanks,

My Michelin 185/70 - 15 XWX on a 5.5 x 15 five bolt wheel fits perfect in the front trunk.
