Yokohama Advan Sport AS vs Michelin Pilot Sport 4 S — Compared

“The Pilot Sport 4's are great tires for dual duty use. You'll want to keep hot pressures below 37-38 PSI. Anything above that they get very greasy, very fast. In the cars I've driven with them (a few BMW M cars, a 911 I think if I remember), you'll usually set your best laps in the first 4-5 laps of a session depending on temps. Once they over heat heat, as with any street tire, you have to park them for an hour to get the temps down again (downside to steel radials). I'd also recommend Hankook RS4s if you want a more durable track tire. That's what I run. Very long lasting, but not as great in the wet as the PS4s would be. Road noise would also be an issue for street use.”

“Best alternative to Michelin Pilot Sport 4S Time for some new tires and it seems like the pilot sport 4s is backordered everywhere in 235/45-17 or similar sizes. Been using the pilot super sport for a few summers and love them so just wanted to get basically the same thing. What other tire in that size is the next closest thing? Some of the competitors aren't made in that size or a close enough one. As far as the tirerack test results for a max performance summer tire the Continental extreme contact sport is available in that size but the other 2 in the test aren't. I'm not set on buying from them just using it to check availability.”

“I tried conti’s and took them off the car after 2 days and went back to ps4s. Obviously on a closed course they feel very floaty around 130 and I’ve had the Michelin’s up to 165-170 and they stay planted. Depends if you drive those speeds, but like Watkins glen you’ll legally notice the difference. It was shocking at first.”
