PSS on the track-can it handle heat?

The NTo5's are a very poor street tire as they are quite slippery till they get a fair bit of heat in them.

I'm going to do my best impression of Captain Slow on the track! Especially at Mosport!

Seriously though i'm an idiot, I meant PSI not degrees.

On that note, i've found it harder and harder to get heat into my NT05 as they've gotten older. Hopefully flipping them might help, but the performance on them tails off pretty quick.

The less tread you have on a street tire the harder it is too get heat into them to get grip.I found that when they are hot the NT05's still have grip till just before they cord.T0yo Ra1's are also just like that.Toyo 888's go off after about 10 heat cycles and getting heat in them helps very little once they go off.

What about a wheel hanger? I really don't see the need for studs if you have one of these:

ECS Wheel Hanger Installation Guide Tool

When removing a wheel, you completely remove the top bolt and insert the wheel hanger in its place. It will hold the wheel, while you remove the rest of the bolts.

Then, just leave it in to hold the replacement wheel, while you insert & tighten the rest of the bolts. Once the other bolts are in, then you can remove it, and insert that one.

In my opinion, it really depends where and how often you switch up your wheels. If you're switching wheels at the track, the less fussing the better as far as i'm concerned - even with a hanger pin, you've still got to line up all the holes, make sure they're clean, take the hanger out etc. Also, if you switch out frequently, I would say studs are better because there is no chance for dirt/dust etc to get on the threads in the hub, which is always a concern when using bolts and switching wheels at the track.

So how were the PSS on the track? Do tell all

[CanAutM3]

Update on a older thread:

Had my first track day of the season this week-end. It's the spring warm-up, so we were at the short and very bumpy Sanair track near Montreal. The weather forecast was for pretty cold temperatures of -3˚C to 6˚C (26˚F to 43˚F), plus I was lazy, so I decided to run on my street PSS.

I was very impressed .

I was outrunning cars on R-comps and the tires held very well overall. Not much wear after five 25min sessions .

They would probably not have held as well in hotter conditions, but pretty good nonetheless .

[swartzentruber]

I have a track friend that has been running PSS tires on his E36 M3, and has been very pleased with their wear. I think he's had them for at least 3-4 weekends, and they still have some wear left. He was also pretty happy with their performance at this weekends event, in terms of keeping up with some drivers in Rcomps, although with cold and occasionally damp track, it was a weekend that favored streets over Rcomps.

I also ran my streets (Goodyear Eagle F1 Asymmetric), and was quite pleasantly surprised by them. It was the first time I'd run on the track in them. It actually got me wondering (as did some conversation with my instructor) if drivers give up on streets too quick. Yeah, the Rcomps give slightly better performance, and may hold up to track abuse better, but high perf streets might work fine for the more advanced driver that knows how to use and not abuse their tires (and wants to have just one tire).

I'll be at VIR this weekend. I'll report back with feedback on PSS. Current forecast is 88' and Sunny.

I am running NT05 staggered setup on Apex wheels. Can I flip the tires on the wheels to extend the life? I have about 4 track days on them.

I think it's possible, though this is quite off topic for this thread. I flipped a set of NT-01s for a bit more use. I think the inside part of the tire is what provides the minimal amount of wet traction these tires have (which is very minimal), so if you flip, don't expect any wet traction at all. Also, I'd only flip if you've done a decent job of wearing them down fairly evenly.

Yes these are great tyres RT615k though are better great on track and road and acceptable in the rain !! Much better than corsas and cups at much lower price

Just remember your tyre wear has alot to do with your style and smoothness and how fast you drive!! Normal road tyres eg Mich SS or P Zero will last if you drive 7/10ths and still learning. If you are going 10/10 ths your tyre temp is higher then a semi slick compound will work better all the same as brake pads.

Agreed in general. But you are missing another variable: ambient temperature.

In cold weather I found the PSS to hold pretty well, where the R-comp crowd struggled for traction.

I've found the yoko's to last forever, and are a great dual purpose tire, have about 6k street miles on them and aren't too expensive, live the tire

i have had similar longevity with my ad08s. i have 9 days on them and they still have a lot left. im very diligent about rotation and flipping side to side also.

Alright guys-having spend the better part of this weekend aggressively tracking the PSS.

Verdict: At the track where temp reached 90'+, they did not become greasy. A few other folks who were running on PS2s had mad greasy tires having done the same run group as me. Visually after each session-the PSS had pretty wear all round.

Side Note: This experience was based on 4-30 min sessions in the novice group which means I may have not pushed the tires (in terms of braking and handling) to the degree as more advanced drivers. My instructor did note that I drove pretty aggressively for a novice (if that means anything..)

I drove about 4.5hrs home from the track the same day with no issues. We also encountered some patches of heavy rain on the way and these tires were a champ even at 70+mph in the rain.

Conclusion:

These tires are excellent all round tires providing exceptional capabilities during the summer be it track or road. Wish it had rained at the track for a bit to explore grip at high speed wet runs.
My money may have been better spent on track tires (RS3 or NT01/NT05) however most of these tires totally suck in the rain which means I wouldn't have been able to drive home. I don't have the luxury of a trailer to carry an extra set of tires. Cheers!

Disclaimer: These tires only had about 1000 miles on them before I took them to the track. Your experiences may differ depending on the usage/wear and miles on these tires.

Great, then these would be a good tire for you on the track until that day comes that you turn them to oil slicks.
Seriously, the PSS has good traction, wet or cold, its just that it isn't made to go as far up in temperature as some other street tires. They are a great all around tire.

I've seen several posts about transporting track wheels in the back seat. Get wheel bags and put a blanket on the seat. Stand the wheels upright and you can supposedly fit 4 across. Then, just strap them down and your trunk will still be available for tools, luggage, etc.

Also, thanks for posting your experiences. I'm in a similar boat: I was looking for one set of tires to do it all. I went with Star Specs, as I wanted something a bit more track-oriented than the PSS.

Next time I buy tires, I'll have a dedicated set of track wheels and probably go with R-S3's. At that time, I plan to get PSS as my street & rain tires.

[turbo8765]

Do any of you guys that have tracked this tire check tire temps? I'm curious how much heat the PSS will tolerate and at what temp they get "greasy".
