Tires. What is every one running?

RE71R

A lot of guys complain about these tires getting hot/greasy after a few laps and wearing out super quickly. They seem to be more suited for autox and time attack formats where grip is on tap right away and you only need to get peak performance out of them for a few laps max.

Did you feel like they get to that duct tape/velcro sound a bit quicker than other tires?

I have RS4s on my HPDE car and they hold up to the heat well and wear nicely at 29-30psi cold with -3.2* front camber. Car's a little under 3000lbs and brakes with PFC08s in 996 calipers.

Tires aren't great in the rain, but they seem to wear extremely well. With only a few event weekends last year and maybe a few this year depending on how clubs get their acts back together, they'll probably last me another couple years. That's unfortunate because I'd really like to move up to some NT01s.

So you dont seem to like the rs4 too much? What did you run before them?

Current - square 265/35r18 Michelin Pilot Sport Cup 2
Previous - square 265/35r18 Bridgestone RE71r

I was running RE71rs for the last year before switching to the Cup 2s a couple weeks ago. Impressions and pros / cons for each listed below

Pilot Sport Cup 2

Impressions / Feel - These really are a do it all tire, quiet on the street (minimal tire noise at speed) yet have great grip on track. For street use, I noticed almost no difference in comfort and noise between the Cup 2s and the Pilot Super Sports. On track, the sidewalls are on the softer side, so there is a bit of a "numbness" at the limit - almost like the tires are greasy even when they are not. I can feel the car lean on the sidewall a bit before gripping and taking the line.

Ultimately these tires are like the "GT4" of track tires - comfortable enough to drive on semi-daily, yet still stout enough to take a beating on track. Pros
Quiet on the street
High heat resistance on track
Great lateral grip

Cons
Softer sidewall -> numbness at the limit


RE71R
Impressions / Feel - These can be used all year round in California and still perform on track as well. These do not have the same street manners as the Michelins, but they are reasonable enough for an HPDE car. Excellent grip both in the dry and wet, and the stiff sidewalls feel great at the limit - lot's of communication from the tire and keeps the steering feel "responsive". When they are hot, you will get a duck tape or velcro unsticking noise when you drive over painted asphalt (eg curbs on track).

These are more like the "GT3/GT3 RS" of track tires, they still work on the street but you are giving up some ride quality / noise for better performance on track.

Pros
Excellent grip in the dry / wet
Responsiveness to inputs

Cons
Road noise as the tires age / heat cycle
wear (to be expected with this kind of tire, but I got 10K and 5 HPDES out of a set)

Michelin SS, but Firehawks are def awesome for the price! run them on my other whips.

What cold tire pressures do you recommend running on the Yoko’s for a HPDE? Just had a set mounted and reading the feedback about softer sidewalls, I’m thinking 36psi to start with and hopefully go down from there.

I haven't done a track event with them yet but will this fall. I plan to start out at 31 psi with the target being about 38 psi hot. That's just based on anecdotal inputs I've seen in various places. I usually found about 36 psi hot to work for the RE-71s so thought I'd try 2 psi higher for the Yoks since that's the difference I 've found to work for autocross. I should clarify that I don't run pressures that high for autox, typically 33f/31r hot for autox.

I just put a set of 265/35/18 square on my car a few days ago. For the money, they're very impressive. The comfort and low road noise mixed with excellent grip and braking makes for one of the most ideal, balanced street tires I've ever encountered. They're punching way above their weight class/price bracket, that's for sure. They run $500-600ish a set which is extremely affordable for a daily driver tire.

Thanks for your feedback

Has anyone tried General GMAX RS?

I have them on my ZCP. Good tire - pretty comfortable and excellent dry grip. I would have never even looked at them, but I had previous model of the tire on my car when I bought it, and when I took it to the dealer to re-finish the wheels, they messed up one tire. So they bought me a set of new tires - had to be the same brand. Since old ones were discontinued they got these GMAX RSs, and they are great. Especially for a free tire

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.

PS4S

[sev]

I also have the indy 500s and even tracked them. theyre a very good tire for the price

[TeddybearCup]

RE-71R because it doesn't see any long commutes other than to and from autoX and track events.

PS4S would be my recommendation as a street summer tire.

PS4 - Couldnt get the PS4S easily at the time i got them otherwise that is what i would have

PS4S I will use all year round (Australia so our winter doesnt require winter tyres... at least not on the West) - they will get used on the track for a few track days here or there as well

I will try PSC2 next and see if they go okay across summer/winter/track... My cars end event is Tarmac Rally which are street surfaces not track surfaces so essentially I am trying to zone in on a tyre that I can use between street and track effectively as Tarmac Rally requires street legal tyres anyway.
