After many tires blowing, I seem to have found a fool-proof way of landing without blowing your tires.
I've only tried this in a 737-800 so far.
Anyway.
Use ILS to bring you to the runway. AFTER the autopilot is controlling your descent towards the runway, make sure your speed is 135kt . As you get
close to the runway, reduce your speed to 125kt.
When you fly over the THRESHOLD (was around 500/400ft for me) of the runway, pause the sim. Set your altitude to 0000, your vertical speed to -200 and
your heading to dead ahead.
Switch from approach mode to Altitude/heading mode and unpause. Your plane should gently touch down on the runway, with all tires intact.
As soon as your main gear touches the runway, disable autopilot and get the nose down. Use reverse thrust and brakes 'till you're slow enough. Win!
I forgot the autospoilers and autobrakes when I tried this, don't know if it will affect the landing.
I landed at -70ft/m when using this, in bad weather.
Tell me how it goes if anyone tries this.
Hmmm... This is good for someone using the keyboard to control the aircraft. Not to mention that this kind of approach has very little in common with
flying. Not all runways/aircraft are fitted with modern avionics/radio systems for full auto-land. What you suggest is literally a 'somewhat
controlled terrain collision' piloting

'Using the reverse thrust and brakes till you're slow enough' is again a violation of safety rules - once at 80kts you MUST disengage reversers
otherwise you risk foreign object to be sucked into the engines, damaging them and maybe causing fire and putting your passengers into harm's way... I
presume you're flying with FsPassengers engaged so you most probably will get penalty points for reversers active below 80 kts...
As for the speeds, even B737-800 can land at different speeds depending on the landing weight. Reducing/increasing the speed during the approach phase
will result into unstable approach and as such should lead to go around situation. This is because when changing the speed, the engines have to deal
with it. Jet engines are slower to respond to speed changes so it may happen that your engine will run at over 60% N1 thrust where it is recommended
to 'final-approach' at 40 - 60 % of N1, which is the maximum to make a pilot sure engines do cut off in time for the flare and touch down.
I know, I know, again, there's someone here saying that flying other way than 'as-close-as-it-gets-to-real' is the thing you should be considering
(instead of finding strange ways to avoid tyre blows) but hey isn't it why we all love to do it?

Good luck!
