•  Rear tyres are subjected to greater loads than the front tyres Consequently, they wear-out 

   rapidly

 

•  vehicle should have less worn tyres on its front and more worn tyres on the rear

 

•  It is required to change position of tyres after certain mileage of travel. This change is 

   called “tyre rotation”

 

•  To achieve more uniform wear for all tyres on a vehicle 

 

• The pattern of tyre rotation differs for the front wheel driven vehicles and rear wheel driven 

  vehicles

 

• A spare wheel generally a standard fitment on many vehicles but can be an optional 

  attachment on some vehicles

 

• The tyre rotation pattern differs for various makes of vehicles
