Rotating tyres every 10,000km will keep your tyres wearing properly. Front tyres always wear a little faster than rears because you are constantly turning them which causes more stress/wear. Rotating these tyres to the rear, and moving the rears to the front will keep all fours of your tyres wearing evenly.
Tyre balancing is done in house with our state of the art wheel balancer. Rims and tyres need to be evenly balanced due to the fact that they are a completely equal circle spinning in one constant direction. If the weight is off on any given part of the rotating rim and tire it can cause a wobble/vibration while driving. Most commonly this happens at certain speeds where the wheel starts to shake from having unbalanced weight in motion. Sometimes this will occur at one speed say 90km/h, and then fade once you reach 100km/h. It causes a discomfort for the vehicle occupants, but can also cause wear on steering/suspension components since it is stressing the parts that the actual wheel bolts on to. Wheel balance can be thrown off by many variants including: Tyre Wear, Rust/Corrosion, Pot Holes, Weights Coming Off. Having a set of four tyres balanced while they are off the vehicle for a rotation is never a bad idea.
