all out tire wear question?

Question

Give me as much explanation of a car tire wear as much as possible and it's grip, heat, how it's recycled, etc
can you explain to me about real life tire wear please. how do they wear down? why? aren't they rubber though so shouldn't they stick all the time? tell me everything? is there anything else? please tell me what you know. tahnks.

well looks like someone from gran turismo playstation forums answered it for me.

Tires in real life wear out all the time. Have you ever watched a real auto race? They practically change their tires every lap so that they can get their grip back.

The tire is constantly in contact with the road. Friction between the two make them very hot (especially with racing slicks at high speeds, this is not so much with your average car on the street, mind you). When you turn hard, you hear the tires squeal across the track.
While all of this is going on, its like the tire is being grinded down. Road surfaces mostly aren't perfectly smooth you know

Eventually, the tire wears down to the less grippy part of the tire. Obviously you won't have as much grip, and will start to be less effective. If you stay out too long with bad tires or race your tires too hard (in real life), you can even cut a tire. (this isn't so much in GT).

Also, different tires have different levels of endurance an

Also, different tires have different levels of endurance and grip. Hard tires, or R2's, have pretty good endurance, while having less grip. The tires are harder, so they are not as sticky to the surface. You will not have as much contact with the road, so you won't go as fast, but the tire will ultimately last longer, and making your lap times more constant. Soft tires, or R4's, have pretty good grip, while having less endurance, for the opposite reasons.

Then there are the extremes of Super Hard, R1's, or Super Soft, R5's. The former should be pretty much used for long endurance races. The latter should be primarily used for 1 lap time trials, as they wear out really fast.

Hope this has helped, and my explanation wasn't too inaccurate

Wow this is so long, I think it deserves a closing.

Answer 1

Pheumatic tires were invented by Doctor Dunlop In the 1,800's Rubber or synethic rubber compounds are softer then road surfaces so the interaction of tire to road earth is bound to cause wear of the tire. Chassis and suspension dynamics determine if the tire is going to have grip let's say during cornering body roll causes the inside tires to become unweighted spin out happens. And when I floor my 400 hp car with 400 #ft torque I can break traction and spin my tires easily. that really accelerates wear. Temp traction and wear numbers and letters on modern tires give you some idea how well the tire will handle and wear.
