Here are some easy ways to tell if you need new tires. First try taking a penny and placing it in between the tire's tread, if you can see the head of Lincoln then it is time to get those tires replaced. Also you can try asking the inspection station when you get inspected for your tag.
Could be your tires need to be balanced or you need new tires.
I inspect the tire and measure the tread depth.
uneven wear on your tire tells me that you dont rotate your tires and you probably need a new set of tires
Where there are new tires, there are used tires. Automotive departments take old tires and restore them or keep the tires in a decent condition and sell them at a much more affordable price.
new tires. If the tires brake, you'll need it
You'd be best to start out at Sam's Club or Walmart automotive center to check the prices on the tires there. These two locations will have the best deals on new tires for you. You can also go to independent auto tune-up shops to look for used tires that will fit your car.

Yes
No the rims do not need to be replaced along with the new tires unless certain conditions require you to do so. The only time you need to replace the rims along with the tires are when you damage or lose them.
In my opinion the new tires go up front. The steering tires need the grip.
