The threads inside a tyre help to give the rubber more strength, particulary tensile strength.
Or do you mean treads?
You can use a penny for that. Put in between the threads then mark and measure the depth on the penny.
Bias ply (conventional?) tires are made with nylon threads layered at a "biased" angle. Radial tires use the same type ply configuration just using steel threads instead of nylon. The invention of radials was huge because more load could be handled by a lighter tire. The steel vs. its load is much lighter than the nylon because it takes more ply of nylon for the same load. **up to a point**. With our current tires a nylon bias ply is better for heavier loads on commercial equipment and trailers because at those weights they are just tougher and the extra ply weight is not noticed at lower speeds.
No, a thin layer of water builds up between the tires and the road, so the car looses contact, a tyre has threads built into it to push and drain water from beneath the tyre, thats why it is usually when tyres are worn bare that aquaplaning occurs.
No, NPT threads are not compatible with NPSM threads. A pipe with NPT threads tapers slightly, while an NPSM-threaded pipe does not taper.
You put them wherever they are needed. If the threads are bare then they need replacing by law. See a car professional. If possible, put the best tires at the back. When braking(hard), the weight at the rear of the car will be momentarily reduced, making it easier for those wheels to break free and skid. By having the tires with the best grip at the rear you reduce that risk a little.
There are two main kinds of threads implementations: User-space threads and Kernel-supported threads. Mikaela
Plumbing pipe threads are squared and conduit pipe threads are tapered.
The long threads are called the warp and the shorter cross threads are called the weft.
Internal threads are threads inside of a hole in something. Like a nut, for instance. External threads are threads on the outside of a cylindrical object. Like a bolt, for instance. hth, Steve
