Life of the vehicle. Know that the older the tire gets the less safe it is. So, if the tire is say 10 years old you would want to drive very slowly if you were forced to use it in an emergency, and get it off the car ASAP.
Its recommended for your donut spare to be ran 50 miles. Donut spares can be driven passed that limit but it can lead to unsafe driving conditions or there may be a possibility of suspension components breaking and/or not working properly.
Off road tires are good enough all season long, they are just like regular tires expect that they can handle more, rough roads, they are a available for any car truck or suv, the mileage is good on them
I check the tire air pressure in all the tires including the spare every oil change or before a long trip.
Yes, they are and last a long time.

As a Small town retail store owner, we have had good luck with the Triangle trailer tire. It might not last as long as a Goodyear Marathon but for the money its a good buy.
Not really. you can get good tires fairly cheap but check on how long they are rated to last.

Falken's are known to be fairly good tires for low prices. They have decent grip, and last a long time but are not the best possible brand. It depends on how much you wish to invest in tires, with Falken's you get your money's worth.
Slicks are great for city commutes.
It is safe to purchase used tires as long as you find used ones that have good treads. However, if you want to be the safest, it is best to buy 4 brand new tires.
If it's a temporary or "donut" spare, it's supposed to get you off the highway and to the nearest service station. And you're not supposed to exceed 50 mph limping there. Those small, cheap spare tires aren't designed to withstand the heat and loading of normal driving -- or even less-than-normal driving for extended periods.
