So, about the flats.

When i bought the car, the 2nd day I was 100km away from home and got a flat. All i did was fill it up at a gas station and drive home.

The next day the tire was completely flat and I put on the spare and drove to Toyota to get the normal one fixed which they replaced cause the car was still brand new basically and driven off the lot less than 48 hours ago.

So yeah...not sure what kind of flats people are getting that they can't make it home?

I guess if the whole tire pops.

I guess it depends on severity of puncture and speed of air escaping even taking out cases of complete blow/large ripping in tire. If it goes to flat in 5 minutes or much quicker, no temporary filling at gas station will help. If i had on average one flat per 2-3 years, i'll better have space saver wheel in trunk for ensurance and piece of mind, if i have no way to predict when/where/how severe i can have flat tyre again, if it will be where roadside assistance can arrive quick enough or not, if waiting for it will interrupt my plans too much or not, and so on. Donut wheel is not THAT heavy to not have that extra ensurance i can rely on, it also doesn't rob one of trunk volume unlike full size spare in AUDM cars, and for track racing it can be removed anyway together with foam pieces with instruments and alikes.

Summer time around town I remove my spare tire but I do carry mini air compressor and tire repair kit just in case. It weighs less than tire+rim. In the winter time it snows here so I carry my spare. My back seats are useless to me so removed those too

My 17 came with the tyre goo, which is rubbish.

I put in a full sized spare, stays in for street duties.

Only time it needs to come out is at the track.

So far I've used it twice now.

Not taking your spare for street duties because of weight loss seems delusional to me.

Opinions may vary

86MLR: you live in land down under. There is reason why AUDM was only market twins were sold with full size spare. Long roads with hundreds of miles till nearest inhabitable place/nearest place from where hypothetical roadside assistance may come. But it's not exactly most common case for twin owners world-wide.

For those of you who removed the spare tire, what are you using the support the trunk liner thing? When I remove mine I can't put anything very heavy in the trunk without crushing the support base back there. Do you just remove everything and put stuff on the bare metal in the trunk?

Happens all the time, and is really the more likely scenario. For example, I've had one flat on the 86. Ran over a gutter spike sticking up between a railroad tie and the pavement in the road crossing. I heard it pop, tire was flat before I could pull over because it had a hole big enough to stick a finger in, no way to temporarily fill that.

If I called roadside assistance it would be a minimum of 45 minutes. I changed the tire in less that 10.

In all my years of driving I've had maybe a dozen flats. In none of those was the flat "fixable" on site with just an air compressor or a can of fix-a-flat. Sure I've had slow leaks but I notice them before the tire goes flat and fix it so I don't get caught on the road.

I won't buy a car that doesn't come with a spare tire of some sort.

yes
