You might add Yokohama A052s

They do not make a 295/30 or a 305 or a 315, or if they do Tire Rack does not list them.

They do list a 295/35R19, but at 27" tall and an 11.1" tread width, I don't know how well that fits in an S550 or an S650 wheel well.

I also do not know how it changes the handling on track (slower, faster?).

I don't think he included any 35 aspect ratio tires, but I can add the 295/35R19 if folks want to add them to the list. They are $477.

Also:

"Track: The A052 works best cold, delivering its quickest times on the first two laps. However, heat builds rapidly with heavy loading, and grip falls off substantially. The tire then becomes rather challenging to drive at the limit. Laps three and four both included missteps as a result. Lap five is indicative of the heat-soaked level of grip."

NANKANG SPORTNEX CR-S​

Has anybody here run these? What do you think of them? How did they perform? How long did they last? They are one of the cheaper tires bossdog listed.

Randy Pobst on the Yokohama ADVAN Neova AD09, which come in 295/30R19 and 325/30R19, which he claims lasts for a 4000 mile One Lap of America on a 4600 pound Dodge Charger Hellcat Widebody Redeye, 16 track events . . . that is a lot of mileage

Yes. I like them. I have improved my PB at our local track with them, though previously on Falken RT615k+ so maybe not surprising. I can't comment on longevity as I have only had them on for a couple of sessions, but they seem to be holding up fairly well.

I am a pretty big fan of these trafeos. Takes a lot of abuse that’s for sure. I thought i was gonna cord out this weekend but the grip seemed to hold and still got a few sessions in them and that’s in 85-105+ heat god knows that the track was.

Main event race we were jointed by none other than Tony Stewart and Boris Said running million dollar porches. Some TA2 chevys held in but pretty cool to have them at the track. And i wonder how they made their tires last a whole 40 minute race? lol

I get it the time trial guy's/gals have a much different tire need than race groups.

I might buy the trafeos again but interested in something similar or stickier that can last 2-3 +weekends 16 sessions on these plus some road miles and might have 4 + sessions left ? Might just run them to the cords to find out

Going to pull them and take a close look at them and my brakes which were awesome

oh yeah Tony won and even though Boris had some issues he came in 3rd

I run them they fit mostly fine a bit of a front scrubbing on the plastic fender wall at full lock at around 1" lower than stock. I like how they handle wet and road use and the taller ratio actually helps with gearing at my local tracks namely Serres where previously I needed to put 4th at some braking zones now I don't have to that much. This is with 3.55 rear end and 7500 rpm red line. Overall the best tire I used in terms of speed it's may be behind the Nankang AR-1/CRS but they are 305/30 and the 295 A052 run wider than a 305 AR-1 but the ratio of the AR-1 helps with a bit more speed out of corners though AR-1 is not good for street at all as it whines and in rain is really scary.

Honestly, after running a slew of tires over the years, sponsored by 4 Tire Companies ( directly or indirectly ) I am constantly amazed at the changing landscape on tires but there always seem to be a reasonably small group of rubber donuts that stand out. The issues almost always comes down to those who want the best for speed realizing that tires are the number one mod for the competitive edge and those that want a tire more for solid fun, but longer wear. If you are doing Autocrosses or Time Trials you have only a few quick tires you should be viewing, with most competitive groups currently pushing 200 TWR rubber.

Price and Performance is not always equal and frankly as our friend in New Zealand noted the Nankang CR-S ( though you only want the Version 2 ) is one game changer. I would personally choose over the Trofeo for price and perfornance for almost any reason.

One has more choices than ever but ironically habit needs to be the one area that many need to view changing as I know a bunch of buddies running the same tire as they did 10 years ago. Taking time to really observe at the track or autocross who is fast, taking time to read the main gurus of tire testing, and really looking at the specific sizing working with one's vehicle can help one go faster. Since it is a relatively expensive mod it is worth your due diligence.

Consider writing your choices down, with special notes and be willing to change your mind. It will need updating as the competitive tires can change and are changing relatively quickly. An example of this would be you should choose a Nankang CR-S V2 over just looking for a CR-S ( and be aware of the difference ) or getting a Bridgestone RE-71RSZ over the Bridgestone RE-71RS. I know new students who would purchase a tire based on a friend's recommendation when the same brand had come out with a better track/autocross tire at a similar price, simply because a bit more schoolwork was not done.

Lastly try to find those who have participated in these events for years and a simple rule to also look for is to also note if those folks are the fast pilots, ha!

If price was no consideration, and manufacturers were shipping you both tires for free, you would still choose the Nankang CR-S over the Pirelli Trofeo RS?

Wasn't the CR-S version 2 released almost three years ago now?

Are tire sellers still selling the older version?

At least on Tire Rack, when I look at 295 and 305/30R19, both list "V2 compound."

Has anyone tried the Gladiator x comp h/p?
315 30 19s are $850 a set. 295 35 19s are $1072/set. No 305s. From looking at very minimal reviews they look like they might fall in an endurance category.

..............and by the way Gunslinger, having run the RR ( Spec Race Tire ) it wears somewhat well, communicates poorly , and it butt ugly slow, part of the reason so many drivers in NASA begged for an upgrade. The R is an improvement yet for the normal track rat a set of quality 200 TWR tires is a better option. I am being blunt as I mentioned to some friends a few years back, since RRs were dirt cheap, that they may want a set just to burn up ( these are folks with 2 sets of wheels ). Knowing how much I hated them and how those of us with plenty of experience thought they a YoYo race tire ( pun intended ) I regretted this silly move. A crap tire is still crap even if it is cheaper. 2 buddies drove them once and sold them off to others - these tires don't talk to you they are mute!

I would choose the RE71RZ, the Nankang CR-S V2, Yoko A052, and the Vitour over the Pee-Relli. Not a fan of the tire brand and won't go into all the stories why, by they often over the past decades have shortages. So many other tires offer better punch for the money, and heck I would get a set of Goodyear F1 3Rs over the tire in a minute.

Haha Bill nuff said. xnay on the toyos….

Life is too short to run crappy tires

So since i need new track tires Bill what would you recommend for the factory 10.5/11” wheels. Second set only track tires? Price is not the issue

Prefer 305/315 for now till
i get a square track setup

Having the 10.5" front and 11" back limits choices somewhat.

Check out the tread width on the Trofeo RS you have now. You will find that they are narrower than almost every other 305/315 tire. My street tires are now Michelin PS4S, and they are substantially wider than the Trofeo RS tires were.

So much so that, for example, if you were to run the Nanakang Sportnex CR-S, you would probably want to run 295/305, not 305 on the front.

305 are 10.9" wide, compared to the original 315 Trofeo, which was only 10.5" wide

Trofeo RS about 3 seconds faster on some laps than Nankang Sportnex CR-S for this driver at the awesome Spa-Francorshamps track in Belgium, but less than one second on the fastest lap:

I got room for more tire with negative camber

19" wheel limits the choices. Might go to 18" if thats advantageous

If you do, then you have to make doubly sure that the barrel design will clear your massive brakes on the front. Not all 18" wheels will fit over them.

Please keep in mind you want the CRS- V2.........................big difference over the straight CR-S and if you find is " El Cheapo " it is the initial version. Tire Rack and other Dealers who focus on high performance rubber will note that the tire is Version 2!
