Bridgestone Potenza RE050A Run Flat vs Michelin Pilot Sport 4 S — Compared

“Quote: Originally Posted by gcurnew I got the Goodyear F1s on my car when delivered and found them surprisingly nice: good grip, quiet, compliant ride.

I know the Michelins are the "go to" tire and pretty much everyone raves about them...but I'm in the camp that thinks the F1s are an equivalent tire. Having had both, I would have just bought a set of F1 rears (my fronts were only partially worn) rather than a full set of Michelins. I've used Michelin exclusively for the past two decades. My car came with the F1s and was pleasantly surprised. Dare I say better than 4S? Excellent in the wet and dry and they don't seem to get greasy like the 4Ss can when pushed. Still don't know how they wear but unless performance drops off or noise suddenly goes up like with Pirellis, I might buy them again.”

“Quote: Originally Posted by D_H I hated the Michelin Pilot Sport 4 S tires. Was not happy with the wear. I wanted a drivable tire, and that's why I got them. They were pricy. Didn't last anywhere near the 30,000 mile range. Lasted just over 15,000 miles. Tire wear was not even, and the performance is a joke. But again, that's not why I got them. Tires always want to slip traction. I'm just going to stick with the stock tires from now on. I was wanting to know what everyone thought about these Atturo AZ850 front and rear tires though. I just put a very lightly used (from a friend) set of Atturo AZ850's in 1LE size on my 2020 2SS (I mounted them on MRR017 1LE Replica Wheels (285/30ZR20 Fronts and 305/30ZR20 Rears)), so far VERY happy with them especially considering the cost... They definitely hook better than my old 275 run flats...”

“I’ll say this. Going from the Pilot Super Sport to the Pilot Sport 4 S of the same size, I’m disappointed in the soft sidewall of the 4 S. This is an 8.5” wide wheel with 235/40/18 tires. The left-right fast slalom action got a bit mushy like the weight transfer was slowed down when I switched to the 4 S. I think a shorter sidewall 4 S would perform better in this way, or the same tire on a 9” wide wheel too. That said, the dry and wet grip is exceptional. To save money, I’d recommend the Continental ExtremeContact Sport.”
