The article mentioned that rotating our tires is important but it didn't state how often we should rotate our tires; every 6 months or once every year? At what point is the tires tread considered to low or what tip can we use regarding tread?
According to edmunds.com, tires should be rotated every 5,000-10,000 miles. However, your owners manual may suggest more frequent rotations, if your vehicle has some specific wear issue.
The standard in the U.S. for checking tire treads is to insert a penny, topside first, into several of the grooves on each tire. If the top of Lincoln's head doesn't go beneath the treadline, you have less than 2/32" of tread left, which is considered unsafe.
Check out this site. It has some interesting points of view on how to get a great deal.
If, as stated earlier, your vehicle has specific wear problems, then address that issue first. -Alignment, camber or shocks can affect tire wear. -Don't expect changing or rotating tires to help with that -it just hides the problem for a short while.
If your tires are bias belted or radial (that covers most modern tires) -reverse rotation of the tire can cause belt failure. -In other words, keep them rotating the SAME way. DO NOT switch such tires to other side or it can weaken the tire structure
