Guest jazzbell Posted January 22, 2010 Report Share Posted January 22, 2010 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.

first corner crash Posted January 24, 2010 Report Share Posted January 24, 2010 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, Quote 4x national champion 6x national runner up. I come second most often but my girlfriends happy.

MOPARGREG Posted January 24, 2010 Report Share Posted January 24, 2010 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? Quote Thanks Greg Link to comment Share on other sites More sharing options...

So how much softer are Extremes over ultras? 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. regards shane a team thunderbird Edited January 24, 2010 by jazzbell Quote Link to comment Share on other sites More sharing options...
John Schoen Posted January 24, 2010 Report Share Posted January 24, 2010 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.

Apparently they are dynamite on enamel or gloss tracks though, 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..............? Quote Lim I enjoy racing. Winning or losing is secondary.

munter Posted January 24, 2010 Report Share Posted January 24, 2010 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. regards Quote John Warren Slotcars are my preferred reality Link to comment Share on other sites More sharing options...
manimmal Posted January 24, 2010 Report Share Posted January 24, 2010 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.

Guest jazzbell Posted January 25, 2010 Report Share Posted January 25, 2010 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. regards shane a team thunderbird Quote Link to comment Share on other sites More sharing options...
smallnails Posted January 25, 2010 Report Share Posted January 25, 2010 might have to give these a lash, i use ortmanns a fair bit after being a nsr tyre man for ages, i still use nsr tyres quite a bit as they also clean my track better than any other tyre i have seen!!!

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 DM Edited January 25, 2010 by dangermouse Quote Link to comment Share on other sites More sharing options...

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 . regards shane a team thunderbird Quote Link to comment Share on other sites More sharing options...
dangermouse Posted January 25, 2010 Report Share Posted January 25, 2010 Thanks Shane might order some supergrips as well as ultragrips next time - pretty happy with the grip on the MKIV and the ultra are great as well cheers DM Quote Link to comment Share on other sites More sharing options...
Dale Posted March 13, 2010 Report Share Posted March 13, 2010 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.

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. regards shane a team thunderbird Quote Link to comment Share on other sites More sharing options...

kennedyrd Posted March 13, 2010 Report Share Posted March 13, 2010 Hi there. Sorry I just noticed this thread. I have used NSR extrmes a few times, and they work well on our smooth tracks, but I have found them to go hard and glaze over when left unused and then when I put them back on they are slippery as hell. I suspect they must "go off" like metal chassis tires do when left. Perhaps keeping them in the fridge might help. As you say they have to be trued really slowly. Also only Superglue holds them onto the rims. They do wear fast which is why I have not used them on the proxy car. They are inconsistent and finicky to use is the best way to put it but when they stick they are almost as good as silicones, but still about .1 to .2 of a sec off a well run in set of silicone tires. The Mclaren Munter talks of that Kieran used to come second at the nats does mid 5.5's on Extremes and 5.4's on silicones. Rubber after silicone? On a gloss surface no problem. Our nationals has to be the best proof. NASCAR was the first class, and Mike did a lap record for the class using the rubber tires. During practice all sorts of tires had been on there. Next class was GpC with silicones. Qualifying and racing saw lap times as quick as ever. I think on ferrodor it would be a problem as the rubber or silicone would get ingrained into the surface.

Guest jazzbell Posted March 13, 2010 Report Share Posted March 13, 2010 Be very careful some super glues will cause the Ultras and extremes split! I use a non hardening super glue on my NSR's Phil how true this is. The other problem is when people use the wrong size tyre for the wrong rim size. 16'' tyre will pull over the 17'' rim,as soon as the glue goes on with in seconds the tyre splits at the joint. So when ever anyone buys NSR tyres,make sure the right tyre size for the right rim size. regards shane a team thunderbird Quote Link to comment Share on other sites More sharing options...
