How do pilots know their way?

Today, pilots navigate using GPS-based systems in their aircraft. They fly between imaginary vertical points known as waypoints that are stored in the aircraft GPS database. With modern navigation avionics utilizing GPS and moving digital maps, piloting an aircraft has never been easier.

Can dry rot cause steering wheel to wobble?

A front tire with dry rot will cause your steering wheel to wobble at low speeds, while dry rot on the rear tires will cause the whole car to wobble. This only occurs when the tread begins to separate from the tire itself—a situation that’s best avoided.

How long are stored tires good for?

Overall, the time limits for stored tires are much the same as for tires that are being used. The National Highway Traffic Safety Administration (NHTSA) and official manufacturers suggest a tire is only 100\% safe to use until it turns 5-6 years old.
