as far as the spare wheel goes then i am only doing what an audi rs6 has as standard.they do not have a spare wheel just compressor and tyre sealent. if the worst comes then i have european breakdown cover.
takin the spare out is only part of what i am doing and its not just for fuel economy. it is performance related that should also give me better fuel consumption when i drive like a judge( not very often
).
the next thing is to remove all the air out of my tyres and refill with nitrogen
