These MPS 4 replaced MPSS on my BMW 6 series, to me these are more of grand touring tyres. They are less noisy, steering is not as responsive, handling is similar but not as good even though the PSS were introduced many years ago. I know the MPSS were replaced by the MPS 4s, but still some praised the MPS 4 when compared to MPSS when they were first introduced.
Talking about the sidewall design, it is dead flat with minimum flange rim protection, this combination makes the tyre look funny and ugly especially since they are on 9" OEM wheels (275 wheel range is 9-11"), the tire is wide at tread and caves in to the rim, also less wider than other same size tyres. I measured the section width on my wheels and they were 260 mm ( they should be minimum of 275 on 9.5" wheels), MPSS measured 280 mm. Going to the front set of 245/40ZR19 on 8.5" wheels these look like bicycle wheels.
In short, these don't look and don't drive like sport tires.
Definitely not buying again.
