There's been a lot of talk about NSR tires lately, especially the newer EVO compound.
When I bought slot cars tires in the past, I removed them from the original packaging and placed them into nickel-sized coin tubes on which I marked the brand and size. Unfortunately, I did not differentiate between NSR's older compound and the newer EVO compound tires.
Retrieving some NSR 5230 tires from a tube I noticed quite a difference in the appearance of the tires. One pair in the photo on the left looked very glossy, the other pair on the right had more of a matte finish. I'm assuming the matte pair are the earlier compound of tires (they were deeper in the tube) and the glossy tires are the newer EVO compound. Is this a good method of differentiating the tires? And if so, where on Earth can the older compound tires be found?
