Train Tyres

Yes, as anyone who lives near "Southern" region in SE England will testify. The old slam-door trains (electric multiple units) were notorious for sliding under braking on wet leaves that stuck to the tracks. The replacement stock, despite being 40-plus years newer in design still seem to suffer the same problem. And speaking (typing) as someone who's recently moved into a house above a rail tunnel, I can personally attest that the problem wasn't there in the summer and is very much in evidence now during autumn.
PS. UK to USA:
Tyre = tire. A tyre can be any removeable material that is attached to a rim.
Autumn = Fall.
PPS.
A wheel is the name for the whole circular entity that is between axle and ground (rail, etc).

The "Swedish scrubber" solution was particularly poorly thought out - as the wire brushes wore down the mechanism came too close to the third-rail.

Why are the leaves a problem? Well, back in Victorian days it was undergrowth that was the problem, as it too readily caught fire from sparks emitted by steam locomotives during dry summers. So mature trees were encouraged, which were typically deciduous, but not a problem to a heavy locomotive that was fitted with a sand-box under the control of the driver.

Yes they can, and do.
Trains do have tyres. They're made of steel and are shrink-fitted onto the wheels. If you closely examine a train wheel you can see the join (be careful if you do this).
If a train's brakes lock up, which they occasionally do, the wheel will skid on the rail and a 'flat' will be worn on the wheel rim. Sometimes this is apparent when riding in an old passenger carriage by the sound of a subdued rhythmic bopping sound.
Locomotive tyres are regularly 're-profiled' to remove flats and reshape their conical profile.

Locomotive and wagons have tyres, they are made of steel and fit onto the wheel itself, and are locked in place with a Gibson ring, which can be seen if you look at the wheels from the inside.
When the tyre is worn down to the wear limits, they can be reprofiled ( cut on a lathe ) or if worn down to the maximum wearlimit, they are removed and a new tyre fitted to the wheel.
The axle is press fitted into the wheels , and then each wheel is fitted with a tyre.

Actually, they can and do. The "tyre" on a train is a friction fit steel rim that the center of the wheel is pressed in to. Normally the rim is heated and the center section is chilled to a low temperature for assembly. As the temperatures equalize, the interference fit holds them tightly together. The rim section is actually called a "tyre" or "tire."
When a train wheel locks up, it will slide along the track and the friction can cause a flat spot. This causes the rythmic "thump-thump" sound you sometimes here coming from a train wheel. It is referred to in railroad parlance is a "flat tyre."

Trains on the Paris (France..for the Americans !) Metro have rubber tyres ! So therefore they can get flats !

Trains don't have tyres so technicaly no. However if a train brakes suddenly so that it skids then the part of the metal wheel that is in contact with the track may be worn flat by the friction and so may need replacing.

No, a trains wheels are made of complete metal lol. the speed a train travels at the rubber of the tyre would be burnt out quickly

No because trains don't have tyres they run on metal rims on the tracks

no trains have no air and is nothing more than a steel chrom-alloy
rim that rides along the track if a train could get a flat tire you'd have to overload it by about 2-3 tons to buckle the wheels but cant be done while train is in motion
so yes you can give a train a flat "tire" but in reality no never ever would happen
