i'm sure none of them do. i agree that "thread" is wrong... just saying that the fact that tire rack uses one doesn't disprove the other. there are lots of things that have more than one acceptable term/name.

HAHA good one.

TREAD

Yes which is stamped on the sidewall.

Easy: tread.

It's tire TREADS. However, tires do have thread, its way under the tread in the form of wire 'thread' and also fabric thread. Wear the tire way past the treads and you will eventually see the threads but obviously this is very very unsafe.

My buddy had a major camber and allignment issue so he was showing major thread. VERY bad.

I should also add: The threads, inside the rubber of the tire under the treads, are part of the structure of the tire that gives it strength. Very similar to how rebar gives concrete strength and how carbon fiber under the acrylic layer gives it strength. Normal passenger tires, which we all have, only have threads along the outside of the tire. This is why when you get a nail on the outside/contact portion, along the tread, it can be repaired because the threads underneath is still holding the rubber structure strong. This is also why you cannot fix a nail/cut on the sidewall, because there is no threads in the sidewall of passenger tires.

This is not the case with big rig tires and trailer tires. They have thread inside the entire structure of the tire to give it additional strength, obviously because it needs it given the heavy loads they're handling. Big rig tire treads can actually be replaced while keeping the tire underneath. That's why you sometimes see large pieces of tread on the freeway . The tread portion, which is basically a giant belt of tread, sometimes wears away and comes off. Truckers often call these 'gators'.

Unrelated: Here's a pic of my S because today, Friday, is a S2000 day. Burn rubber everybody!!! No threads visible here!

With that comment, what "approves" and "disproves" the proper term? Take it a tire manufacture's website?
http://www.michelinman.com/automotiv.../warranty.page Tread. No thread anywhere.
http://www.goodyear.com/en-US/services/tire-warranty/ What is covered and for how long. Tread. No thread anywhere.
http://www.hankooktireusa.com/serv/w...&childnum=1%0A Tread. No thread anywhere.

Let me know when you find a website talking about tire thread. Even the "threading" underneath the rubber to reinforce the edge isn't referred to as "threads". The proper term for that would be steel belts.

My guess, this whole thing likely stems from people hearing "tread" for the first time but processing "thread" in their mind.

There is no proving or disproving anything. It is "tread".

"3 the thick molded part of a vehicle tire that grips the road.
• the part of a wheel that touches the ground or rail.
• the upper surface of a railroad track, in contact with the wheels.
• the part of the sole of a shoe that rests on the ground."

If you hear anyone say "thread", simply slap them across the face until they say it correctly. Slap them hard.

Now time to go read up on how tire treads perform in that one tire thread.
