Plane tires

Hi,
do you know why plane tires are smooth flat ?

It beacuse of friction or something like that

That is what I thought but why won’t they use standard tires like those for cars

If a jet plane had good friction tires like those on a automobile it would be a rough ride for one. Smooth tires make for a smooth ride. Also, a plane doesn’t really need gridded tires because it’s not trying to tackle rough terrain. For the most part, all airport surfaces are flat. In addition, when an aircraft is rolling down the runway, the tires heat up which causes friction.

one point to consider is that aircraft don’t need the wheels to provide traction to move. The engines provide the thrust to move, there fore the wheels don’t need to grip the runway in the same way that a car needs to grip the road.

Also a car with smooth tires is perfectly fine and won’t be very dangerous but if you try to turn you will lose control, it’s the same with any aircraft they only will go in straight lines at high speeds so it’s perfectly adequate

again depends on the surface. On a race track, cars will have a smooth tyres in order to reduce friction, whilst general purpose road tyres or off-road tyres will have a different function again

Yeh I think the post above is right

That’s basically what I’m saying, if you want to drift then yes you might have some pirelli P Zero tyres

Here’s the thing. If you have flat tires, you have the most grip, but can’t displace water. So, they make them as smooth as they can to maximize grip and take into account weather. Here’s and F1 tire, very flat, maximum grip, but hydroplanes on water. image

Plane tires have some channels to handle the water. Also, having ridges on planes that land at 170 knots creates too much heat. That’s why tires are the way they are.

We hydroplane once, it was scary and fun

So basically if planes used car tires on landing they would just burn up?

They’ll explode, the compounds used in aircraft tires are different than consumer tires. They’re not built to withstand the strain of something weighing that much hitting the ground at 300 km/h. Most car tires are not built for that kind of speed.

They’ll heat up and shred themselves to pieces. Not the best way to land

very interesting, I didn’t know anything about that
