Want to know exactly the age of your tires for your Range Rover?
 

Find the DOT # on the tire. Then look at the last four digits. Example: DOT 4HT4503. This translates to 45th week of the year of 2003! Tires seem to last 5 to 6 years before they become unsafe according to different articles. Of course it they are damaged off road, are defective, show dry rot or have been driven when out of alignment they age much faster.
