Tires need the grooves to be able to get a grip when weather is not the best. They provide a place for water, ice and snow to go and allow the rubber tread to make contact with the road.
Racing cars often use tires with no grooves at all, but the weather has to be dry and the pavement clean. On a passenger car, even a little water can cause hydroplaning, where the tire is on water rather than the pavement.
If you drive with low tire you can have a blowout, which can lead to an accident. This is dangerous to both you and other people on the road.
The tires you have on your car are your contact with the road. They are possibly the most important part of having a safe drive. Keep your tires in good shape and do not abuse them by hitting kerbs or other solid objects. If tires are getting worn, or unusual wear patterns get professional advice.
Can be that they're simply worn out. Particularly if it's a rear drive car, then accelerating hard will put a lot of wear on the rear tires.
Too much camber and the tires aren't aligned right so the tires get worn easily
You tires are worn out because either the car needs an alignment, you are running them with either too low or too high air pressure, suspension parts are worn, steering parts are worn, or the tires were defective.

Your car probably has abnormally worn in tires, caused by misalignment. Worn rotors can cause this as well.
The front tires move when you accelerate a front-wheel drive car, while the rear tires move when you accelerate a rear-wheel drive car. All-wheel drive cars have power going to all four tires when accelerating.
In terms of car tires, there is no definitive answer, it depends how you drive.
Good question! The car wheels are out of alignment,or warped. or the tires are out of balance. The shocks or struts are worn out. There are other parts in the wheel mounting worn and can't maintain straight forward movements.
If the treads lack definition and/or if the car "pulls" to the left or right.
Tires out of balance, worn t-rods, Bad u- joints, Belt broke in tire. Have a mechanic take it for a drive and get their opinion.
