Different tyres on staggered F sport setup

[MD93]

As most of you guys know, the F sport has staggered wheels at 225/40R/18 on the fronts and 255/35R/18 on the rears, making it hard to find good tyres for the rears. Is there any issue in using different tyres- say Michelin Primacy 4s on the front and Pilot Sports on the rears/ does this affect with the AVS in any way?

No it wont as long as diam within approx 10%.afaik. 

I use Michelin PS4 all around in 225 and 255 same as standard. Very happy with them. Set front toe to '0'
