C43 Estate tyres (not crabbing related)

[ocd]

Your advice would be appreciated.
68 facelift model running eun flat P Zero 225/40 R19 up front. They are in need of replacement, but the rears are OK for another 6 months at least. 13k miles done to date. Do I need to replace all of the tyres together or is it permissible to replace the fronts only at the moment?
They crab a lot in the cold but I'm not bothered too much TBH as my old C63 used to do it as well. Thanks

Good practice to replace in pairs on same axle , but I don’t think you need to worry about the rears until they are in need of replacement.

yes definitely good practice to at the very least have the same tyres per axle. I recently bought an old e63 and it had michelin PS4 on the front and conti Sport contact 3 on the back and it is fine though when it gets cold , the Michelins have far more grip and rolling resistance than the contis so it feels slightly odd to drive but still safe enough .

what did you decide to do in the end?
