    Yep.
    Fwiw.... I wouldn't mix tyre type on. Any vehicle whether its the car, bike or wife's jeep.
    Just my 2 pence worth.

    100% only if you drive in a straight line.

    The rim protection on my 4S tyres seems to be perfectly fine & the same as the Cup 2's...

    Why MPSS on the fronts and not rears?

    For what it is worth I also run 4S on rear and SS on front, manly due to rears wearing out ahead of SS.

    It works well, although for continuity I will likely go 4S on fronts when the SS have worn.

    What I did find with the SS is grip was good to start with, but after 4 years of heat cycles the grip dropped off significantly (I do low mileage so tyres last a long time). The 4S instantly felt better, but likely due to age and freshness.

    Better cold weather/wet grip, otherwise I would challenge anyone to find actual night and day difference on the road.

    The generic PS4S have squishy sidewalls and having driven a car with a set fitted unfortunately they ruin the feel too much for me to consider them. They do have better traction, although if that was the sole priority it would have made more sense to buy a quattro!

    On my M4 I found the MP4s to grip better on the rears and by leaving the MPSS on the fronts they seem to handle the front end weight better due to more rigid sidewalls.

    I think quite a few have found similar.

    I'll be doing the same setup on my M2C when the current MPSS need replacing.

    Exactly my point all along.

    It worries me the amount of people can't "feel" the problem with PS4Ss.

    I have confidence if Michelin make a star rated version they'll be ok. I'm certain they'll have to harden the tyre wall again though which means the straight line grip advantage PS4Ss have will be negated.

    MPS4 need a few extra PSI in them, they are a better tyre for sure, just need a bit of air.

    Not true. Depending on sizes. The 285/30/20’s have an identical stiffness of sidewall at 99Y. This has been covered before on a similar thread.

    for your star rated version maybe.

    I tried all sorts of tyre pressures.

    Same here. The 4S side wall is too soft (especially for the weight of my roof:D)

    So if both tyres have same rigid sidewall what is the benefit of MPSS on fronts?

    You can’t run 285 30 20 on the front.

    Most people found the 19” to be a problem, certainly the larger 20” seems to be up to the job. I have 285 30 20 rears and am very happy with them.

    MP4S rears and MPSS fronts is the optimum mix? Better turn in on MPSS?

    You all must be more tuned to the road / feel than me...... I'm pretty sure that the average petrol head wouldn't be able to tell the difference between 4s and ss on normal roads, never mind the difference in a few psi tyre pressure.
