I have removed my spare wheel to save weight and have a tyreweld bottle in the boot. I think this is legal and helps the mpg a little.

I believe it is, but by using this to repair a puncture you could end up ruining a perfectly good tyre which could've been repaired.

True but the spare wheel and tools weigh 4.5 stone (27.9 kgs) so must affect performance a tiny bit.

I would keep the spare in the car as what will you do if you get a huge gash in one of the tyres

Yes had not really pondered that situation. I will put it back in for long journeys.

Tyreweld is perfectly legal, if you order a new Fabia/Octavia/Superb now without adding a spare wheel to the options list then you will get a can of that product in place of the spare. If you go down this route, also carry a tyre inflator because the can or tyreweld does not have enough air to fully inflate the tyre.

The 'blow out' scenario is a potentially scary one.

Do you have roadside assistance? - could they take to a tyre place on a flat bed should the worst happen.

As commented above (and in previous threads) some cars no longer come with a spare....

I run a can of tyre foam and just check the spare in for long trips.
