Do you have a code or link to these 'new' tyres?

I got these codes off NSR's website, it's a useful list:

Looking for those NSR special black tyre codes?...
5260BLACK (4) 19.5x11 for 17.3 wheels
5261BLACK (4) 20x10 for 16.9-17.5 wheels
5262BLACK (4) 19.8x10 for 15.9-16.5 wheels
5264BLACK (4) 19x10 for 15.9-16.2 wheels
5265BLACK (4) 19.5x13 for F1 wheels
5265M (20)
5265L (50)
5265XL (100)

I've used the 5262BLACK (4) 19.8x10 for 15.9-16.5 wheels on a couple of cars, the last of which was Slot Rally last week.  I predicted they'd be great for such purpose and wasn't disappointed.

Tonight I've prepped a pair of 5265BLACK (4) 19.5x13 for F1 wheels for my NSR F1

Truing these is a long winded exercise, NSR Ultragrips are a piece of cake in comparison, my Hudy truer couldn't cope but my RSM3 managed with 180 grit wet & dry with water brushed on the tyres.

They feel hard wearing like Supergrips but grippy like Ultragrips.  They also need careful handling when fitting on a wheel as they permanently stretch unlike the other rubber types from NSR that spring back.

I'll give the NSR F1 a run tomorrow to see if lap times compare to well treated NSR Ultras.

...one thing that is in their favour, although treating seems to help they don't really need any.

Anyone try the grey tire on wood?  I’ve only used them magnet racing on a Carrera track with good results and wear characteristics.

Hi mate, 
I'm running the NSR grey tyres on both my Scalextric Trans-Am and NSR Blancpain GT on wood tracks. They certainly grip and  I think they run better on the slower Scalextric Trans-Am, while on the NSR Blancpain GT car the tyres appear to grip a lot more and offer up a lot more tyre chatter on cornering and hard breaking, they still provide superb grip.

Try fibre tape on the bottom to dampen the chassis/pod movement. I use the same tape I clean the tyres with, cheap black cloth backed tape.
