Maybe he does not want to rotate tyres at all and prefers to let his front tyres wear out. Then move the rear tyres to front and fit new ones to the rear. That is workable, but regular rotation every 5000 kms and then replacing all four tyres is a better plan. In the latter case his new tyres should ideally go to the front for reasons pointed out.

RKS,

I'm gonna keep it as it is and I got alignment, balancing done before i installed new tyres.

But Michelin site also say that two new tyres should go to back axle .

"Install two new tyres on the rear axle
If you need to purchase only two new tyres, insist that they are installed on your vehicle's rear axle. New tyres grip the road better and when the two new tyres are mounted on the rear, they will help reduce the potential for your vehicle to fishtail or hydroplane in wet conditions."

Not applicable for cars like the 800 for sure.Tell me something will be doin high speed antics more or braking more?
If your answer is the latter than keep new tyres in the front and trust me on this i have a 9 year old 800.

Many people do not rotate tyres and then the front tyres get worn out before the rear tyres, which usually get worn to about 50% by then. In this case, it is advised to move the rear tyres to front and then put the new tyres at the rear, as mentioned by Michelin and other tyre/car companies. In your case if you fit the new tyres to the front, there is not much possibilty for fishtailing as your rear tyres still have plenty of tread left. You can keep your new tyres at the front and then rotate your tyres at regular intervals.

Better tyres have to be on the rear axle.

That is true if the used tyres are already worn to ~50% remaining tread or less.

By your logic, let the new tyres go to the rear in the present case. After about 5000 kms, the front tyres would be still more worn as compared to the rear ones, so they cannot be rotated to the back as per your requirement (better tyres at the rear). So your logic will not allow tyre rotation at all in a FWD car.

Starting from brand new tyres in all four wheels, after about 5000-10000 kms you are advised to rotate tyres. But immediately after rotation, the "better tyres" would be at the front. There is no problem in this case, as the difference in tread wear is not so large as to cause aquaplaning or fishtailing.

On the other hand, if the owner does not intend to rotate tyres at all, I agree with your logic. After front tyres are fully worn out, the partially worn rear tyres should be moved to front and new tyres should go to rear.
