Current hotness in track/street tyres

[Kaiser]

have run Toyo R1R and Federal 595RS-R and can recommend both whole heartedly

+1 for the R1R's, coped well with track days on my road car. Now that i've got a dedicated Bugeye track hack, i'm going to try out Khumo V70A's hard compound Semi's

[Coffin]

I have FZ201 Mediums going on as we speak .... will give some feedback hopefully later today/tonite if the rain holds out

[neil_se]

The FZ201s would be awesome, what did they cost each?

We're running ADVAN Neova AD08s on the MX5, they're bloody excellent. Also as part of running them you're eligable for the Neova Cup which just ended for 2011, so it's a whole new ball game for 2012. There's also a cash back deal.

The ADVAN Neova is capable of astonishing lap times. Results such as a 1:44.37 at Eastern Creek Raceway, a 1:07.4 at Wakefield Park and 59.945 lap time at Tsukuba Circuit, Japan have all been achieved on this street legal road tyre

I've gone for Nitto NT01s, treadwear of 100 so about as grippy as you'll get without going full R-comps.

NT01's are a full semi and may not be road legal. NT05's are and similar to KU36's and similar crossover tyres.

I always heard when you are going to track a car you're supposed to bump up the pressure rather than lower it to stop them peeling off the rims.

Is this just the case for street tyres due to weaker sidewalls over a semi or full R spec tyre?

[old_geez]

I run my slicks at around 23 psi cold and 26 hot. Same with the semis.
Street tyres you put up to 36 cold

[200MPH]

Nt01 are same rubber as r888 and RA-1, so definitely a genuine r compound tyre. I don't see the point in a half/half tyre like ku36 or a08. Just go full r comp and be don't with it. You won't wear them out worth a damn as an occasional weekend driver, they only get worn when on the track in my experience. Then again, I don't drive hard on the roads. Quick car means you can't really. I've run several sets of RA-1 and r888 over the years. Now onto v70a for a drive end tyre, seems good also.

Yes

I'm not a fan of r-spec tyres on the road.

A sharp stone can puncture them.

If you get them hot and then drive over some gravel they will media-blast your underbody/guards/sills/etc for you (this is why race-cars look so shitty up close).

NVH is annoying.

Standing water can render them undrivable.

Until they warm up they can be a bit skaty.

They tend to flatspot sitting in the garage - creates extra NVH.

The grip is so high that you have to drive stupidly fast to slide the car around.

Enjoy driving your prius/camry

You complain about NVH on a performance vehicle do to its tyres?

The thing is when using semi slicks on the road is that they are never going to get hot enough to work properly and if they did get hot enough the dry grip available is way beyond what you can use on the road anyway. For anyone who has not driven on a circuit using semis, to get an idea of the speeds involved just look at some public road targa incar video with a speedo.

But it seems to have become a bit of a status thing to use semis on the road when something crossover like a KU36 or NT05 would be legal and better in every way.

Hence another reason why the Neovas are so good

I used A048s every day on my old 120Y and R888 on my 1600. I found that they offered way more grip than street tyres under normal driving conditions (cant comment on wet roads never tried it). I got a year out of the R888 driving weekends/track days, and even then it was only the left hand front tyre that was fucked (I assume from roundabouts) That said i wouldn't pay full price and do that, used to get the A048s for $20ea from Aussie Racing cars and the R888s were half price off ebay.

Esp on a FWD car, I find that the fronts sorta come up to temp but the rears stay cold, so unless you're *really* up it. the handling's really weird.

BTW Boxer what's the go with Neova Cup for 2012?
