Firestone FR740 vs Michelin Pilot Sport All Season 4 — Compared

“I use these on my F80 M3 competition with the 666M wheels for the winter. I had Continental DWS 06 Plus on my E90 M3. The PSAS4 have stiffer side wall than the DWS06 Plus, so the ride will feel more sporty if that's what you're after. PSAS4 also have slightly more dry pavement grip and tad more steering feel than the DWS. The DWS is a tad bit quieter and softer sidewall. Superior to the PSAS4 in light snow. Dry pavement grip is still amazing. I have 2 sets of 666m wheels for my F80 comp. One set outfitted with Pilot sport all season 4 and the other set outfitted with Pilot sport 4s.”

“Michelin PSAS4 vs Conti DWS06+ Recently did a change-up, went from a set of Continental ExtremeContact DWS06 Plus (driven 17,000 miles / 27,360 kilometres) to a new set of Michelin Pilot Sport All-Season 4. I drive a VW GTI and live in Southern Oregon with a 75-mile (120-km) roundtrip commute everyday and here are my observations: the Michelins are a touch quieter and dare I say offer a more ‘refined’ ride the Contis felt stiffer (subjective) but has better cornering without a doubt. Ran both sets at 39 psi (269 kPa) for the 225/40-18 size. the Contis definitely brake better under cool rainy conditions (ambient temp was about 13°C) the Contis perform very, very well in snowy conditions but I’ve yet to test out the Michelins in the same environment. I drove the Continentals on more than 10,000 miles of snow just last winter. the Michelins quickly lose grip when I dump the clutch in first gear, compared to the Continentals. The ESC on my GTI turns on more often with the Michelins as well. the Michelins are ever so slightly more fuel efficient but only a 1-3 mpg difference at best, I found Overall, if you’re looking for a more performance-focused (and light snow-biased) UHPAS tire definitely go for the DWS06 Plus. As for me I’m delighted with the PSAS4 overall, but it’s also because I’m highly biased on Michelins as a brand. Read more”

“Michelin Pilot Sport All Season 4 efficiency FOLLOWUP: On a recent drive, similar speed (70-80) and same route, I managed to get 290Wh/mi. Only notable difference was that the outside temperature was now 25-30C (instead of <10C) In trying to debug WTF tesla is doing, I started looking at the CAN bus. It appears that the car tries to keep the battery in the 30-35C range, so pretty much all that extra power usage was the car trying to maintain battery temperature in cold weather rather than the tires. Original post--------------------------------------------: just FYI about Michelin Pilot Sport All Season 4 235/45zr18 98Y I knew to expect a small efficiency hit, but this is almost as bad as when I towed a 2000lb boxy trailer. M3LR, stock 18" wheels and aero covers, no roof rack, no bike rack, driving in ~10-15C ~70-80mph funny part is that with the $0.46/kWh supercharging for the California portion of the road trip, driving a Tesla comes out more expensive than a 22mpg gas car @$4/gal :rofl: Read more”
