Tire Rack Consumer Review of the Michelin Pilot Sport 4S

Original tire size for my car is 235/40-18. Currently run Michelin Primacy MXM4 on 18 factory rims during the winter. Bought a set of summer wheels in 19 and ran 235/35-19 Michelin Pilot Super Sports for 40,000 miles (worn out) until changing them out for Michelin Pilot Sport 4S in same summer 19 size.

In short, the new Sport 4S tires in 19 ride as smoothly and quietly as my MXM4 in 18. The Super Sports were also noticeably harsher over expansion joints and other road impacts. A great upgrade.
