I have wanted to replace my Pirelli 18/19" with Michelin Pilot Sport 4 S. Looking at the on-line tire suppliers could not find replacements for the 205 fronts. I did not want to go up a size and figured I would have to go to another brand. For the heck of it , went to Costco on-line and found a listing for the 205/40ZR18 Michelin and original size for the rears. Strange that others do not list?Michelin Pilot Super Sport
I installed new tires yesterday. I got 21,000 miles out of the original P-Zeros. The rears were danger thin, but...
I wanted a longer lasting tire without sacrificing much grip. In the 18/19 set there just isn't any choices. So I went up one size. After reviewing the good selection of tires and juggling my compromises, I chose the Michelin Pilot Super Sport.
215/40ZR18 (205/40ZR18 OEM) front
245/35ZR19 (235/35ZR19 OEM) rear
I based my decision on many things.
- Weight: lightest in this size.
- Tread width: widest in this size.
- Tread wear rating: 300 so it will last longer than 20k without giving up much traction. Besides, as a daily driver I don't drive on that ragged edge. When I do push the canyons, I'm still not on the ragged edge.
- Price: well, uhm, actually expensive compared to the others.
- Reviews online and some people I know: it's getting good reviews.
I did my home work and found that the OEM Pirelli P-Zero are small for their size class with a tiny tread width. These Michelin's are large for their size class and I'm going up a size. I was unsure if they would fit, maybe they'll rub the springs. Will I need spacers?
At the tire shop we mounted one front and one rear and did a test fit. All seemed well. It looked and felt like plenty of room. So we mounted the other two and finished the job. With about 50 miles now, all seems good.
I measured the ride height before and after. The larger tires raised the car 3/8 inch. Probably not enough to matter. If I had coil overs, I could lower it back to stock ride height.
I was concerned about speedometer error as well. I used my smart phone GPS to check the speed before and after. With the P-Zeros, it was 2 mph under. Meaning if the speedo showed 60 mph, I was actually doing 58. With the new larger tires, I was 1 mph under. 60 showing is now 59 actual.
I need to let the tires break-in before I can offer more of a review. Part of break-in is waiting for the bead-lube to dry. I don't want to spin the tire on the wheel. I will also need to check the pressure soon as it will drop during break-in. So far I like them.
