Hello, 

Thank you for writing in. These are great quesitons.

To start, suspension components can start to wear down after 30,000 miles. While they are typically designed to last over twice that, you can start to check on them at around that mileage. Suspension problems can cause a variety of symptoms, from vibrations, to shaking, to extra bounce, to creaking and excess noises. If you have noticed a change, it may be worth having someone look at it. 

When it comes to tires, there are three main things to look at.

First you want to check the tread depth. As long as you are well over 2/32nds of an inch, the tires are legal to drive on and should be okay. As they start to approach that point, you need to have them replaced. To give you some idea of what 2/32nds of an inch looks like, you can look at a US penny. From the top of the penny to the top of President Lincoln's head is 2/32nds of an inch. 

Secondly, you want to make sure that the tread is wearing evenly. If the tread wears more on the outside, inside, or in certain spots, there is an issue with your suspension. 

Lastly, you want to make sure that your tires are properly inflated at all times. Tires naturally lose air pressure monthly, and you likely will need to add air every two months. If the tires are loosing more than this, then you may have a leak or damage that warrants replacing the tires.
