Mixing Pilot Sport Cup 2 and Pilot Supersport

On the road, what would be the downsides/risks of running PSC2 at the front and PSS at the rear, both in OE sizes on a M135i. They don't make a rear PSC2 in the OE size.

The ones I can think of :
- it would neutralise the car or maybe make it rear happy.(benefit?)
- water displacement would be different as the front tread is shallower and void/rubber ratio lesser than the rear. Unpredictable wet handling ?

The benefit would be a more resilient front tyre as the front MSS is quite fragile on the shoulders. Particularly on track. I am fully aware it's not a track car btw...

Tricky one, so much depends on the car and your driving style.

I've run AD08R's on the front and AD08's on the rear on track, the only difference between the two is that the compound is considerably grippier on the R's. I didn't enjoy it much. Having less grip on the back made the car too snappy under hard braking and cornering and even though it's a FWD car it was actually much better when I swapped the R's onto the back.

For road driving I preferred the gripper tyres on the front though.

Never a good idea to mix tyres really, especially when one is considerably stickier than the other as in this case. I'd just run a 'square' setup anyway.

Yes square would work as the 245mm fit at the front but not on the stock rim. Might consider 235 square AD08R or buy 17 wheels if they can clear the calipers...
