It varies largely depending on your driving patterns, You should replace your tires when the tread depth gets to 2/32" if you only drive in a dry climate. If you drive in lots of wet weather and snow then replace them when they get to 3/32". Place a penny in the tire tread with Lincoln's head down. If you can see the top of his head you are at 2/32" and they for sure need replacing.
In my opinion tires should be rotated every 3k miles along with oil change and filter change. Tons of people agree and I have always done this on all my vehicles
Ask bridgestone !
You change tires when they are worn out, not at a set mileage.
You should really rotate your tires every oil change to guarantee full even wearing on the tires but at least every 5000 miles or so
Some say to change your auto tires every 5000 miles. Other people just check the tread on their tires and when the tread looks worn, they switch their tires.
There is a way for you to change the tires yourself, which can save you money. There are many videos on YouTube that show you video demonstrations on how to change a tire. Also many websites such as wikihow, offer instructions on how to change your tires.
depending on the tire and how you drive, on average i would say 35000 to 40000 miles
All the tires should be the same size. If the other tires are in place you should be able to get the size from the other tires. If not the size should be on a plate inside the drivers side door with many other specs.
First off you should not install tires that are not the correct size. But if you do, make sure the tires on each axle are both the same size. Both front tires same size, and both rear tires same size.
To change kilometers to centimeters you would have to multiply by 100,000. 6500 kilometers is equal to 650,000,000 centimeters.
If the tires are starting to look bald and warn then it is time to change them, your local garage will be able to tell you and give you an estimate on new tires
I imagine they change tires every stage, because there is no time to do it during race time
