Well, there's a smart idea. Unless you get a blowout somewhere out in the sticks. Then I'd say you're royally screwed.

Yup. That would be an issue

From a practical point of view though, the foam can't fix a torn sidewall which i assume would be more likely in low profile tyres rather than a nail. Still, worth considering. I have carted a full size spare in the back of my Vectra for 15 years, never needed to replace it on the side of the road.
I wonder if the spare tyre is part of collision absorption system, it is between the crash bar and rear axle and seating.
I havent had a puncture in all the time iv been driving (6 years) and then had 4 in a month

Can always use run flat tyres, but I think they weigh more.

would it be worth looking into a space saver prehaps?? smaller wheel hopefully means less weight?
also how much does the AC system typically weigh?? Mines currently not running and im tossing up whether to fix the pully or take the whole thing out to reduce weight?
havnt used it in the year its been broken :lol:
also on the topic of fuel in the tank, I used to know someone with a 350Z who never filled up more than $20 at a time and was managing an extra 100kms over what the car typically averages due to the lack of weight. The issue with that though was his fuel was technically more expensive as he would pay for it on cheap days and expensive days too. so i guess it didnt really work finanically.
Ac compressor weighs about 8kg, if you pull all the other parts that will be a bit more, there is the heat exchanger and plumbing.
Z350 is a heavy car, a 20kg weight saving is not as noticeable as in a Barina. But a tank tank is about same as a small person... you would notice that.
I ment the full works. Compressor, piping, core etc. It means a different sized belt but bonus is the belt is only driving the altinator, even though the compressor pully is clutched I think it would still have some sort of mass to it, even if its a gram. Doesnt mean you would notice though.
