Hi guy's,

I know most racers out there who choose to run NSR tires run super or ultra grips.

But how many guys out there have tried the NSR extreme tires?

There a tire designed for race only.There made to suit 16'',17'' F1 and fly classic.for the plastic tracks out there,they a very gripy choice of tire.

Designed more for the plastic i beleive the extreme are..

Here in adelaide our tracks have alot of grip,[timber] in testing they were some of the quickest times i've put up with extreme tires on.Only problem they went off quick when they became hot.One tire comes in mind i could compare it to is the ninco prorace .

For a good clean surface timber timber track,i think they'd work rather well.

The other thing,when truing the extreme tire,a lower speed had to be used to stop them burning and balling up.

I would like to know if anyone out there has tryed them and here your feed back.

If nobody has,i'm willing to send some out for people try.Free of course. :)

Regards shane a

hi Shane. I would be a little surprised if nobody tried them in the New Zealand proxy can am event as they would seem ideally suited to the smoother surfaces there. When tyres get too soft for the surface they run on they marble or "go off". I remember a certain individual who tried a set of slot.it f15s on the rough ferradore perkins tack at thunderbirds who was left with what lokked like a melted block of cheese after about 10 laps. Apparently they are dynamite on enamel or gloss tracks though,

NSRs are probably my favourite tyre. I havnt tried the extreme tyre though. I only use the ultra & supers. My track surface is low sheen acrylic paint like what you would roller on your internal walls in your house. I have found that the ultras on higher rpm cars like slotit ballup even on my track. Particularly the right hand side tyre as my track is mainly left handers. They dont ball up really bad & can be trued up again. My track is not really abrasive at all but I thought that the balling up on the right rear was when the tyre runs accross the copper tape. Thats my theory, im probably wrong.

So how much softer are Extremes over ultras?
Thanks
Greg

The only way you will find out is if you try .So pm your address and i'll send a set over.

They are a higher profile,very good for the GT cars.

know harm in trying a set.Then you can judge for yourself the difference between extremes and ultras....

After your test, you can give us some feed back and thoughts. :rolleyes:

I have tried the 19 x 10 size on our clubtrack (Ninco). The grip was excellent, better than anything else. Durability was not so good, after about an hour they looked like a pair of well-used F1 slicks and fifteen minutes later they started to shred. Great tyres if you don't mind changing them each week. :rolleyes:

I have run them on our 100ft. Scaley Sport track and found them to be around 1 second faster per lap than the Ultras (car was a NSR Ford Mk. IV non-mag). Durability was very good but then, the Ford was pretty light with an all up weight of 76gms and the slippery Sport surface would hardly cause any tyre abrasion. Using them on my NZPR Can Am entry is an interesting thought but not having a smooth surface routed track to test on is sort of holding me back unless I want to take a gamble. The fact that my Can Am car is quite a bit heavier than the Ford is also another deterring factor. Russian Roulette, anyone..............? :rolleyes:

I enjoy racing. Winning or losing is secondary.

I havent used them myself,I am using ultragrips on my proxy car(oops shouldnt have said that) but a fellow racer (Kennedyrd) has tried them on a Slotit McLaren on my track.
Any time under 4 secs is a quick time and it wasnt long before the tires had found their groove and the car went under the aforementioned time. Not many rubber tired cars have been that fast before as silicones are the norm if you want speed.

are we talking treated nsr tyres?(treatment not legal where i race) i've not yet tried the extreme, but ultras without any treatment don't do it for me. NSR's are excellent in my applications for noise reduction, and work very well as standard parts on the 917's after 2-3 minutes warm up time. i have found mjk's, brm's, tr racing tyres and ortmann old,blue and comp all deliver better pace - on my set ups where i race. the only exception i have found is on my gt40 mkiv only old ortmanns deliver better pace, and it took a long time to dial out the chatter caused by the huge grip.


Shane, I'll get Ged to have a chat with Chris so we can get some down to test at melbourne model raceway.
My mum says I'm an excellent driver

Manimmal,

NSR Xetreme tires are like every other NSR tire,all un treated.I wish i did'nt even mention this sort of thing in another post,someone els just blew it out of proportion.

Changlaw,

After reading his post,i'm convinced they'll work well on a clean gloss surface .His test,1 second quicker than ultra grips.That difference of time speaks for it self. :)

munter,

If you guy's run silicons,i'd like to know how the NSR'S react ,because i know rubber tires dont like to run over tracks that pepole use silicons. ;)

NSR'S are a must for glue and true.

I have a gloss coated track. I mostly run silicones but I have NSR Ultragrip on my Fly 917k and 908/3 I also had some success with them on my Rev/Mon Lola T70. I have an NSR MKIV I think it has Ultra but they may be Supergrips (it is the gulf car) which holds the lap record n my track. Grip isn't a problem.

I don't race on my track just drive the cars for fun. I don't have any trouble with mixing the NSR and urethanes and silicones. Last night a did a few laps with my slot.it followed by 30 odd laps with my 908/3 no problem. I think the silicone problem is with tracks which are rubbered up.

I will need to glue the Ultras on but I am not sure which glue to use on plastic hubs. I haven't yet because I ordered 1 set and have been trying them out on different cars. I probably need about 3 more sets :)

cheers

Dangermouse,

If the NSR MKIV has the same tires on it when you brought it,they'll be super grips.All NSR cars are released with supers.

As for the right glue,i just use zap a gap/medium.I've got onto the stuff they use in europe now,It's called
UHU super glue .Once i give it a try i'll let you know how it works.

Another thing with NSR tires,its a must you fit the right size tire to the right size wheel.Reason being a 16'' tire will slip over a 17''wheel,tight fit,but soon as you glue the tire to the wheell,it rips the tire clean in half .

Thanks Shane

Hello shane, I have never tried the extremes, I read they are the gun tyre on ninco plastic in the Italian championship.
I started on supers, kind of felt I had to talk chris into handing over the ultras the first time. Does t-bird hold good stocks of the 19.5x12 extremes?

Having said that though, glue true and treatment seems to make more diff than anything. But I am chassing tenths now especialy on my non mag cars.

Shane, doesnt the super glue leave rubber on the rim when you remove tyres or do you stick the rim on a mini lathe for a clean up? Have you tried non hardening glues?

Aussie,

Just scrape it off with hobby blade,then a light clean up with fine paper.

Note never use to much glue.You only want the glue to run on the diameter of the rim.
To much glue can make the top of the tyre surface stick to the larger diameter of the rim .
The flutes i call them.
This will effect the performance of the tires and performance of the car.
