Hey Guys, just ordered a set of 4 Bridgestone Potenza S007a tires from tire rack and since they didn't have a direct comparison test between the two tires I figured I'd mash together their test data and share it here.
First price for 4 (this is based on my tire sizes, your results will vary):
MP4S $1630
S007a $1092
Next tire rack brief description:
MP4S
A couple of quick thoughts here. I get skeptical whenever a reviewer starts to sound like they are the product developers extremely proud mom. Come on tire rack you seriously can't think of a single thing you'd improve. I know that MPSS have long been considered the standard of Max Performance Summer street tires and that the MP4S were designed to exceed that, but seriously nothing. Also interesting note here is that Tire Rack has the MP4S listed as a max performance tire and the Bridgestone S007a listed as an extreme performance tire. I'm not 100% on this but I think in the tire rack category hierarchy Extreme is a step above max. For the record all the top Michelin Tire offerings are listed as MAX while all the top Bridgestone Tires are listed as extreme. My guess is that these are specified by manufacturer and only really play a role on what tires tire rack decides to use for their direct tire comparisons. That at least explains why I had to keep flip flopping between two browser windows to compare the test results of each.
Now for the data.
Stopping Distance 50-0 Dry:
MP4S 80.20 ft
S007a 78.60 ft
Stopping Distance 50-0 Wet:
MP4S 108.80 ft
S007a 118.30 ft
Average Cornering G-Force Dry:
MP4S 0.92
S007a 0.93
Average Cornering G-Force Wet:
MP4S 0.78
S007a 0.78
Slalom Time Dry:
MP4S 4.91
S007a 4.97
Slalom Time Wet:
MP4S 5.53
S007a 5.70
Lap Time Dry:
MP4S 29.78
S007a 29.98
Lap Time Wet:
MP4S 33.05
S007a 35.57
My thoughts,
For years Michelin Pilot Super Sports have been a unicorn in the tire world and thanks to them leading the way we are finally seeing suitable alternatives coming to market. The largest differentiating factors between the MP4S tire and S007a is wet stopping distance, and price. I daily my S550, but drive very cautiously in the rain so couldn't justify the extra cost (perhaps I just jinxed myself with that statement). There are currently manufacturer rebates available on both tires, but be aware that the Michelin rebate expires on the 4/18. I also lucked out by ordering tires on the wife's laptop and had a ebates app pop up getting me an additional 4.5% rebate. April seems to be a very good time to buy tires.
One last note, tread wear rating on the MP4S is 300 while the tread wear rating on the S007a is 240. I don't trust these numbers at all, but I will be sure to mention it in a review update if I start to notice the Potenza's wearing noticeably quicker then the Michelin Pilot Super Sports they are replacing.

MP4S
- What We Liked: Does everything asked of it at a very high level.
- What We'd Improve: Nothing.
- What We Liked: Offers a nice step up in dry traction without much sacrifice to comfort.
- What We'd Improve: Could use some additional steering feel and an increase in wet grip.
