Has anyone had experience of using both Ortmann and NSR tyres on Carrera track, without traction magnets?

I would be interested in hearing about your experience and comments. Any feedback would be very much appreciated.

With many thanks,

Russell

I've used both on Sport track, and would imagine the differences are similar for Carrera.

The biggest difference will come with tire prep. If you just run them out of the package, they'll both have excellent grip.

NSR tires, however, benefit greatly from two things. First, treatment with NSR tire oil. Once that has been fully absorbed (a few hours, so best applied AFTER a race night), and just before a race, you clean them with lighter fluid. I have no idea what chemical process occurs, and it only seems to work on NSR tires with their oil, but the result is amazing the first time you see it. The shinyness from the cleaning stays. It looks wet, still. The tires have more grip than any other tire I've used. Touching them feel like they might be sticky, but they're not. It's crazy.
As they get dirty, they lose grip, but that depends on how dirty the track is. Cleaning them again will bring back the grip, but less and less each time until you re-oil them.

If you prepare the NSR tires as above, there is no other tire I've seen that comes close to the level of grip they have on any track short of putting actual glue on the tires/track (a-la 1/24 commercial cars). If you don't, then they probably end up about equal. I would probably give the Ortmanns the upper hand because urethane in general deal with dirty tracks and tire wear better.

I've found quite a bit of variation in Ortmanns, some work well, some don't. IMO you're better off getting NSR tyres as the compound is a lot more consistent.
We race on Carrera track at my local club BTW.

I prefer rubber style tires, like NSR, Slot.it or BRM, even without tyreprep I just find they give a more pleasant grip.
The Ortmann tyres I find will give you good grip too, but they make most cars feel a little stiff and unforgiving. The way they run out of grip is a little more abrupt than NSR tyres for example, "rubber" tires in my opinion will give you more feedback as you are approaching the upper limits of what available grip there is. That makes the driving more intuitive and enjoyable in my humble opinion
. I also don't like the way any urethane based tyre will affect the grip for other types of tyres. I have a 30m Carrera track currently, but for me the same comments goes for rough Ferrodore tracks commonly used here in OZ.
Get some of each and see what you prefer, as it will depend on several factors as usual in this world. Having said that, if you use no tyre prep oils at all (not allowed on our regular races, and why introduce another step of preparation) I find the best tyre out there at the moment is the Slot.it F22 shore, they offer fantastic grip on a "cleanish" Carrera track.
Happy slotting!

There are several different formulations of Ortmann tires and those perform differently. Some people prefer the older formula tires and those are getting hard to find. One thing to remember is that Ortmann tires are not cast in machined molds, that is why they tend to be cheaper, however they are less likely to be round.

Hi Russell, My club track is carrera and we have lots of experience with ortmann and other makes of tyre.

A few years back, ortmann tyres were the 1st choice as they gave great grip and consistent performance and needed no treatment what so ever.

However, since ortmann changed their compounds/ ingredients, they have been good, but never as good as the originals.

NSR are very good on our track, but you have to constantly prepare them with an oil based tonic of your choice to maintain top performance.

Now, from experience... and contrary to popular myth, once you start mixing ortmanns with treated rubber tyres on the same track, the ortmanns are finished. You may as well throw them away as the oil residue that is deposited on the track kills what ever grip the ortmanns may have had.

p.s. we don't race with magnets.

Hi Russell ,

mixing ortman and any other tyre on a smooth track like carrera doesnt work to well especialy if the rubber tyres have been treated .ortmans work best as a control tyre ie if every one uses them or if the guy who has raced on the same lane just before you has used them .best thing is to use the same rubber as every one else if possible ,however I suspect you are looking at proxy racing so its going to be a gamble any way .good thing about using a control tyre would be that every one has the same compound so theoreticaly its an even chance for every one and its down to the grip your chassis generates .

if u use orts and the grip goes off u probably have oil or other treatments picked up,to regain there grip remove the tyres or wheels if there glued on , and wash in hot water with plenty of fairy liquid to get the oil out of them and there good as new,have done this on lots of cars,cheers

I know this is a reletively old topic but I've only just found it


My home track is carerra at the moment and I've run both Ortmann and NSR and the best and most consistant grip I have found comes with the NSR Zero grips on the rear, I never thought it would work but I've just this minute tried it on two, 2wd cars and the grip seems just about perfect, not too much that they want to tip on every corner and enough not to lose time sliding

Sadly, nobody is making any distinction between NSR 'supergrip' or 'ultragrip' tyres, or the specific cars, or magnet/no magnet/wieght variables, so no posts have much meaning beyond talking about brand names in very broad and generalised ways.

The best thing to do is buy a set of each for one of your cars and try them out. It really is the only way you will learn the accurate answer to your original post. And don't worry about the chemical additives, just use the tyres.

I can make a distinction on carrera track, zero grips are surprsingly the best, super grips are good but can have too much grip even on standard corners, unltra grips are also good but a bit slidy, by far the easiest to drive with but loose quite a lot of time with the sliding.

I have nothing against running any tire with no special prep. However, NSR actually recommend oiling and cleaning their tires with lighter fluid prior to racing. They were designed for that regimen, and that's when they have the MOST grip. Some people don't like that much grip, and it can be a bad thing on some tracks. Treated as prescribed, an NSR car can easily wheelie out of the slot if given full power suddenly, when the tires are still freshly prepped.
I'm not saying everyone HAS to use their recommended prep, but it's important to note that this is not an invention of silly speed demon racers, but actually NSR's own design and recommended practice for their tires.
If the desire is to get the most grip possible, give it a try.
In any case, as Screwneck said, the best answer is experience. Try a few on your own track with your own cars and controller, and see what you like best.

all good

Here in Portugal, mostly run Carrera and Ninco track, but more in Carrera.
We have a regional championship this year was played with the Reynard 2KQ Sloting Plus Carrera track, here we run at 12.5 volts.
And with the RT Tires Soft Scaleauto 20x12 mm, hit records for all tracks, the car is stuck .....
tires must be glued to the rim, not centrifuged.

Tires Ref:

before starting the race, spent the first with this product ..

Product Ref

http://www.criccrac.com/fichaprod.php?id=1...ximamente=false

but only put the product once at the beginning ...... because of regulations.

these are now substitutes for old Slot.it P1, which were the best tires in our tracks, after treatment with oils

I don't know this for sure, but a reputable ScaleAuto distributor here in the states uses their tire cleaner when running their tires all the time. He told me that, more or less, it's Naphtha (lighter fluid) in that nifty applicator bottle. Great job cleaning tires and improves grip nicely.
