I need 2 new fronts on my TD4, it has Bridgestone Dueller HT684s on it at the minute which have listed diameter of 26.8. So I contacted my local tyre dealer and they can only get HT689s which have a diameter of 27.1.

So if i swap the worn rears to the front and put the new tyres on the rear will it be ok?

Thanks in advance of your wisdom

Hi Rob tollerence of no more than 5mm allowed front to rear !

better than the audi tt quattro .... 2mm
I suggest trying to find the 684's or just bite the bullet and get a full set of something.

Bridgestone Dueller are over priced for what you get tbh.
