Hello guys.....have a question about NSR tires ....anyone know what evo mean for the NSR tires ? it looks like the tires with these letters EVO are different from the others of the same size .... have they changed anything? the grip is the same? 

thanks.....

Evo tyres are different. 
Racers report differences in truing, grip and wear.
You'll just have to work with them and learn how to look after them.

Yep, they sure are, as NF said.

I asked the NZ distributor to ask NSR for me, as our local guys have been unhappy with them, and I had used a set on a new GT3 and was struggling for usual grip levels.
NSR reply

regarding your request, I can tell you there is no substantial chemical difference.

 
It's just a new product ?
 
I wish you a nice day.

But I suspect the words "no substantial chemical difference"  equate to Bill Clinton saying " I did not have sexual relations with that woman" 
Or the dentist "It won't hurt a bit"  - No, it will hurt a shed-load, like having your teeth polished with a chainsaw.

If anyone here has found a different method or procedure (think dark arts treatment - someone please pass me the methyl salicylate when they've finished their shoulders) which will bring them up to the grip level of the original tyres, I would like to know. Soon !
I have a few packs of Sideways Hi-grip soft wide left, which are similar at 18 shore, but they are just one size and profile. 
N22 are just a gnats whisker off the grip level, as are Hi grip medium.... and both only come in two width and diameter profiles.
And they are both deleted, so we have tyre-aggeddon approaching.

Been through tyre-a-geddon before and survived.

Slot.IT E1 was the tyre of choice for years at our club on ninco track. 
There was a famine on these tyres that lasted 6months or so Racers started experimenting.
At this time we hosted an NSRGT weekend where NSR-Red were the  mandatory fit.

Now e1 are only used where the classification requires Slot.IT tyres. 
NSR red seems to be evolving as the tyre of choice but others are showing promise.

Slot.IT are dropping f22 and n18. 
A New tyre G25 is being produced but I've not heard any feedback on it efficacy.

N18 is history. N22 are going  - but still being sold by Slot.it.

G25 is a quite different beast. Obviously the shore rating is quite a lot higher, so it is a harder tyre.
We race on wood, so are aiming for total roundness, as our running surfaces are hard and glossy, and utterly unforgiving of anything with a glimmer of variance.

It is also a bit of a pig to true, it will melt at the slightest invitation - at around 3 degrees Kelvin on the lathe :)  And lay black gooeyness all over a rotating drum given half an opportunity.

I set up some to use on a range of GT3 and GT1 cars, and potentially Group 5. 
I have them really true, - after a lot of effort, and a couple of drum cleans of my Tyres Technology lathe and Hudy using solvent and a toothbrush - and about 5 re-finishings till I was happy.
But they just aren't giving me the grip of Supergrip, Ultragrip, N22, N18, or Hi-Grip soft.
They actually remind me a little of Pro-speed to true, but are between Prospeed medium and Prospeed hard in feel and in truing process.
I have subsequently thrown about 8 different solvents at them over a few weeks, from basic cuts, through to vegetable turpenes - d'limonene+Aliphatic solvent blends (citrus hard surface cleaners to the housewife) And of course, the usual range of oils and penetrating oils like WD40 and CRCs

They are stable, I'll give you that. Nothing seems to drop that shore, nothing degrades or bubbles them.
I sometime felt like I was trueing or finishing Indigrips or Supertyres silicons..... 

They still work fine, just as if they had just come off the lathe for the final time and cooled, but they are still close to 25 shore, and still don't hookup quite as good as any of my preferred tyres.


Fortunately from a personal perspective, I have about 30 sets of various sizes "old" Ultragrips, some Hi-Grip soft in both widths, and lightened Reggio to the tune of about a New Zealand wide 18 month supply of N22 in both sizes as soon as I heard the news last year. - About 300 packets remaining after I told everyone to fill their boots....

Funny Alan, the only E1 I ever use, are on 14mm Slot.it rims, on small cars like Scalectric BMW minis.
They work okay at small scale where you have greater body height to track width ratio, but aren't ultra grippy for us on wood.

Some of us here are thinking of entering the next Auslot touring car proxy. There is a tread on this in 'Tips & Tuning'. Soft rubber tyres don't seem to last the series. Do you think G25s might be more appropriate boots?

Whose proxy? Is that one based in Australia?  ( where a lot of tracks might still be finished with abrasive paints as a solution to dust problems), or the NZ originated ATCC one run by Dave (aka Crockett) with a mix of entrants from both countries? 
As I can't see any proxy thread updates that tie up with your post.
If it is one based in Oz that I don't know about, that may be the case, you'd need to research with the host about host track finishes.

If it is the ATCC one run by Dave Carter for about 4 years so far, with a lot of tracks in NZ, tyre life should not be an issue. All tracks here are usually gloss or semi-gloss, and tyres last just about forever.
- I have an ex proxy car from when I ran the Group 5 proxy, still on the original Ultragrips after 7 years....... and still winning at club half it's outings.
But I think Dave ran one year with track hosts in both countries.... you'll have to check. I couldn't comment on G25 outside of our gloss track experience.

If it's Dave's proxy and you need any info. Holler, and I will ask him at club next week.

Shame...it was getting interesting and tyreageddon hasn't passed over two years later

[BAracer]

I managed to buy up a few packs of non-evo tyres before they ran out, and they will keep me going for a few years yet.

Denis on the zoom chat suggested SI G25s are gaining popularity amongst his colleagues. They don't aim for a polished finish and retain the grinding lines on them, and they are competitive...
