Tires. What is every one running?

[EthanolTurbo]

I'd be interested to hear feedback if anyone has tried both Federal rs pro vs Hankook rs4. Surprised not seeing more rs4 given that they are supposed to last a very long time and do well in hpde sessions.

Anyway, I run 265 ps4s square street and track. The tire is amazing, kinda. It is super comfortable on street given the soft-ish sidewalls, but on track, the meaty and sticky outer shoulder grips surprisingly well (it also wears pretty fast, and I know I need to look for a different tire for track). The downside on track is that comfort thing I mentioned, the sidewall feels squishy and I feel like the car bounces a bit in rougher corners due to weaker sidewall.

595 RS Pro/RSRR is bang for the buck best track tires you can buy, and the best tire on street for grip+straightline purposes for the money. They can hold 600+ wtq in a straight line and for cornering they're extremely sticky and responsive. They're basically a cheaper RE71r. I found the RE71r to have even better responsiveness and communication, but in terms of daily driving you can't go wrong with any of them: they're both loud as fuck, somewhat rough yet offer excellent grip and braking. I will test RS4's on another set of wheels when I get them. 👍

Yeah for real. That's why I don't run them anymore... I was paying $1k/set on my E39 M5 and going through 2+ sets a year.

Also, no point in getting RE71r for track when the Federal 595 RSRR and RS Pro exist. They have similar levels of grip and are 50-60% of the price and last longer.

Agreed, RE71R is an auto-x tire, there are way better options for 20 minute track stints. Hancook RS4, Federals, Star Specs, Rival-no-S, and Azenis are all tires that don't get nearly as greasy in track sessions. Now if your doing time attack or want to be the HPDE winner, then RE71R is your track day tire.

RE71 is still king, but in tyre cycles, it's an old tire. I think it came out when the Z2 was the hot tire, and Dunlop is on 4 iterations down the road from that tire. The RE71R is that good. I hope they don't just discontinue, but introduce a new tire that's even better!

Yea, it's a great tire for motorsports activities, especially autocross. It's also a great track tire but does get greasy after a few laps but grip is outstanding. My only complaints centered around street manners where I found it to be pretty harsh over things like expansion joints or similar and they are very loud. But that's the trade off for grip it generates which I was willing to accept. They also tolerate limited camber better than the Yoks.

I DD them because I get them heavily discounted. They last about 9k miles... Insane grip though and good wet weather performance.

They do seem to run a little large but I don't have a direct comparison. I ran 275/35/18 RE-71Rs and am running 265/35/18 A052s since they don't come in 275s. The Yokohamas are not quite as wide as the Bridgestones but pretty close. A 275 Yoko might be a tight fitment but would try it if they ever make one. The A052s don't have a rim protector - or at least not as pronounced as the RE-71s - so a little different visually but fit the 9.5 in. wide rims perfectly. FWIW I've heard that the RE-71 may be discontinued soon but haven't confirmed.

can you comment on sizing since another user said they run much larger than other tires?

After several years running RE-71Rs I switched to the Yokohama A052 this season for autocross and track.

After several years running RE-71Rs I switched to the Yokohama A052 this season for autocross and track. I also run them on the street between events but the car is not a DD. Compared to the RE-71R lateral grip is similar but wouldn't say better necessarily, longitudinal grip is definitely better and they are much more street friendly in terms of impact harshness and noise. Due to the softer sidewall they aren't as responsive as the RE-71R so not quite as good in transitions but excellent steady state grip. I also run about 2 psi higher pressure than with the Bridgestones and wear has been fine. I haven't done any track events yet but I've been told they don't get greasy like the RE-71s after a few laps. They also need a lot of camber or will wear the outside edges much faster, I've heard reports of only getting about thirty autocross runs on heavy, front camber limited cars like the M3. I wouldn't recommend either for a DD with the Michelin and Conti being better choices for street driving.

Currently running PSS, Have not heard of PS4S but after this thread might need to get those once Im finished.

P4S is the replacement of the PSS.

PSS has been out for 10ish years, time to incorporate new technology. You can still buy the PSS carcus But the sidewall will say continental extremecontact.

RE-71R is a "200 TW" DOT R-compound. Stiff sidewalls too, great for autox and the first couple sessions on the track but it'd be hard to DD it IMO.

my car's 90% track and 10% street. i only drive it on the street when i'm either taking it to a shop or driving to the track.

RE71R - barely lasted 8 track days for me. amazing grip for just a few laps, then you have to cool them off.
NS2R - claims to be a 200tw tire, but grip was rather disappointing.
A052 - Never had the chance to mount them, they were SUPER oversized than what's claimed.

Now I'm comparing AR1 to NT01.

ALso consider Federal FZ-201M, they supposedly wear like NT01's and are cheaper. You can get them in E46 M3 friendly 265/35/18 or 285/30/18 from Philstireservice.com
