When the tread (the pattern in the tyre) is wearing thin.
In Britain the law says the tread must have a depth of at least 2mm. Other countries may have different legislation.
Winter tires should be changed out when the tread has been worn down to around 1.5mm to 1.6mm in thickness, after they have been worn down more they are considered worn out. To measure the tread of ones tires one should use a tire gauge which can be bought at websites such as amazon.
Rims and tires should be changed yearly to keep them in best performance and avoid safety issues. Your local garage will probably do this for you cheaply.
You must get your tires changed every six years.
Someone is joking with you , there is no such thing as blinker fluid and the air in your tires doesn't have to be changed , just the correct tire inflation pressure should be maintained
If you changed them yourself it is recommended that you get an alignment done or do the alignment yourself. If a shop or mechanic did the work they should have done the alignment themselves.
Yes they could .
There is a jack on the bottom of the cars that raise them up when the tires are changed.
The tow in should be set to 1/4" measured with the tires installed. Castor is factory set. Camber should be 0 but can be changed with the shock on a Yamaha. Club Car and EZ-GO cannot be changed.

To avoid accidents when the airplane is landing.
Tires are changed during an auto race because the tires get worn down by the track. It is safer to have good tires than to have tires that are worn down that could blow apart and cause accidents.
