I wouldn't replace two tyres that had done only 8000 miles as if you replace all four tyres they are unlikely to wear evenly
The recommendation for safety to counter oversteer on a rear wheel drive car is to put the two new tyres on the rear and the two 8K tyres on the front. Other way around for a FWD car because the rears hardly wear compared to the fronts.
