REPLACING ONLY TWO TYRES?

Normally you should buy four tires at a time for an automobile but not everyone can afford to change all four tyres at once. So the next best thing is to change two tyres on either the front or rear axle. Most people think that the sensible thing is to change the front tyres before the rear tyres.

I recently found myself in that situation. The mechanic at the dealership told me to put the front tires to the rear and put the new tires on the front. It made sense when he said it but, as it turns out, it’s not the correct thing to do. 

When replacing only two tyres, the correct thing to do is put the new tires on the rear of the car with the older tires on the front of the car – it prevents fish-tailing during a rainstorm.

You don't have control over your back tyres, so you want your best tyres at the back when entering corners on a wet road. The greater tread depth in the back helps maintain control in wet and slippery conditions. The front tyres can be controlled/steered.
