Tire rubber is mostly left behind as fine particles - rubber dust, if you will. This rubber dust doesn't just sit on the road; it is blown off by wind or washed of by rain, and it ends up in the environment.

No they wouldn't. You need deep groove tires for mud
Rubber trees are fibrous rooted so they do not go deep.
Standing Knee Deep in a River - Dying of Thirst - was created in 1993.
you make an incision deep enough to cut through the latex vessals.
Q-tips shouldnt hurt. dont go deep down in their ears though.
I would have to assume that your question is concerning the run-flats they use. The other tires are just a steel belted radial design, basically, with a prescribed compound, hardness of rubber, per track. There is a little more to it than that, but not much. The run flats are a tire, within a tire. The inside tire even has a pressure setting, which affects outer tire pressure. Most of the street versions of run-flats, rely on a super rigid sidewall. And there is very little rubber, in tires anymore. I don't know if this is a deep enough answer for you, but, if not email me, and I will explain further.
you can get a tire shop to measure the tread depth and they can let you no or if they are all cracked your tires should be rotated every 3000 miles (along with oil change). tires should be replaced if tread is less than 3/32nds of an inch deep. should not be used util tire is bald. if tires have been stored a long period of time check them for cracked rubber. Use your discretion , if unsure, ask a tire dealer. They will look at them for you and give you the best advice.
Winter tires have a deep and differing grip pattern on then which is designed to push snow and slush awy from beneath them. Summer tires are more designed for basic wet and warm conditions
Tire noise can be caused by the tread pattern used on your tires. Off road tires have a deep tread pattern to give better grip on soft surfaces. Change to a road tire. Road noise can also be caused by worn suspension components, especially the rubber bushes. Check that yours are not worn. They go soggy or split with age.
Deep tread added to snow tires.
Usually a 5/8 deep socket with rubber "keeper"
deep pot holes
