Are you a complete idiot? Do you have no comprehension on how tyres work? Sorry to sound harsh, but that's just the most stupid piece of advice I've heard on here in a long time.
If mixing tyres front and rear is bad, then just how suicidal do you have to be to have three different makes of tyre on one car?
With all due respect, I have worked for a major lease company for the past 5 years as a Fleet Controller, and I authorise in excess of £30,000 worth of tyres every day on various lease cars, varying from Aston Martin DB9's, Ferrari's to Fiat Pandas.
Please explain how mixing tyres on a 206 CC is going to make a difference with regards to handling or safety? It is a Peugeot 206 for the name of God, not a powerful RWD or AWD car.
I have access to every tyre technical bulletin from every car manufacturer, and I can assure you that Peugeot have no isues with mixing tyres on a 206. I'll even forward you the number for my contact at Peugeot technical if you wish to give them a call.
The reason why my previous post was not in much detail, is because I posted it from my mobile phone in work.
You are the idiot my friend.
Perhaps you would care to post up the lease company name as I am sure most members on here would want to know that when making their choice.
BTW, GLWS of your ZED.
