I'm curious to hear what differences are known between the Michelin Pilot Sport 4S tire variants. Tire Rack stocks 3 variants (so far?). In the comparison tool, the differences I see are the following: Clarifier: "N/A" vs. "N0(Porsche)" vs. "TO Tesla, Acoustic Tech" Price: increasing from left to right in the chart below UTQG: 300 vs. 300 vs. 500 (all "AA A") Tire Weight: 23 vs. 23. vs 24. lbs. Tread Width: 8.5" vs. 8.6" vs. 8.8" Country of Origin: FR vs. FR vs. US I'm not sure what to expect regarding performance difference and tread life among the 3 flavors. @[email protected] - Any info to offer here?
