Tires. What is every one running?

[BBRTuning]

Running MPSS, buddy was also running MPSS but recently switched to RE-71R and found they have a ton more grip. Interesting to hear so many people running PS4S

Yeah, not surprising though. The PSS and PS4S are really NOT high performance tires, at least in the world of sports cars. They're a great tire if all you do is drive on the street and occasionally hit a few turns in the canyons, and you'll probably love them if you're coming from something atrocious like a PS2 or a Hankook V12 Evo. The PSS/PS4S are pretty shit if you mainly drive canyons, and forget about tracking on them unless you're just out to have some fun in beginner or low intermediate. They really don't handle heat well and don't even hold a candle to a proper performance street/track 200TW class tire for feedback, grip, and consistency with heat. The sidewalls are also quite compromised and favour ride quality over responsiveness and feedback. The stiffer your suspension/bushings/chassis is, the more you need a proper supportive tire sidewall or else you'll just feel the tire rolling around as soon as you load them up.

With that said I understand why they're popular, they are a great road tire but if you're planning on getting more serious with your car and your driving then it's time to move on.

Firestone Indy 500's here. Great daily tire especially for the price. At 265/35/18 square I would go PS4S as price is not dramatically more. Around $1000 or so for the PS4S. I compromised and went 255/35/18 square as the Firestones were significantly cheaper in that size. With a rebate it was like $530 installed. Given my car is my daily driver, I personally couldn't justify paying almost double for the PS4S in my preferred size.

Yeah agree, ps4s is great street tire and can do ok on track for lower level groups. Sidewalls don't give confidence as they feel super mushy. I switched to Federal RS-Pro. I honestly can not say they are much louder on highways due to my diff whine and exhaust volume, but the sidewalls are super stiff (to the extent that I need to reduce camber all around coming off ps4s) and they handle the heat pretty well, at least enough to have proper fun. Not for chasing pb or lap times, and probably not as good as rs4 or re71z but cheap.

RS Pros for the win. I got my set for $560

This is also pretty interesting, how much faster is a Cup2 vs a PS4S: https://www.youtube.com/watch?v=aMv64liOqIE

I'll throw in my support for Hankooks RS4s. I've now run them all summer with a few track days and see very little wear. Grip is great, maybe others have more but I am not trying to set track records so its more than enough for me. What was a pleasant surprise is the street comfort and noise - these tires are very comfortable for daily driving. Rain traction is also very good, in contrast to what others have said in this thread, both on track and on street. I was originally planning on getting a second set of wheels to run PS4S on the street but these tires are so good it makes second set of wheels unnecessary. Very happy with them.

Just installed a set too and my tire installer had a hell of a time mounting 275/35's on 18x9.5 Arc 8's due to the sidewall stiffness.

The PS4S replaced the MPSS, so it's to be expected.

I had a similar experience mounting them lol very stiff sidewalls but they’re still less noisy than other Federal tires. The grip and feel is great. I’d probably buy them again

Yeah they are no joke stiff. I had them off the rims at the same time as ps4s, I could easily compress the ps4s sidewall with my fingers, not on rspro.

I'd love to do a back to back comparison vs rs4. Folks I have spoken with that have tried both say rs4 does everything better, even after adjusting for price.

PS4S for street. Ignore other options as you will regret going with something cheaper, they are a compromise that isn't worth the savings.

However, if you've always run cheaper tires and want to continue running cheaper tires, you won't be missing anything.

Assume most people asking about tires are also not equipped with $2500+ per corner suspension 😂

No experience with PS4S but I’ve ran PSS before and you’re right. They handled daily street driving just fine. Just cause you spent more on something it doesn’t automatically make it better than something that’s cheaper

I'll say it again. PS4S is great for a street driven M3 in the OP's scenario. They handle everything he is going to throw at them in Hawaii. I'm unaware of another tire that will compliment the E46 M3 without making a sacrifice outside of cost, in his climate.
