Nope..

The RT-615 is based on the ST-115 rubber compound. They are an agressive "looking" street tire with a high temp compound, but they are a street tire only.

Hope this helps.

we really need to have an ASN definition of the term R-compound it looks more and more like the line is becoming blurrier.. anyways Joe is correct of course.

In the SCCA there is a tread wear limit. I think it's 180, but it might be 200? Neither the less I'm sure this is the new non-R Axenis. I think It's time we made a similar rule.

KLZEMX6, in SCCA they have a very popular street tire class called STS, and Falken has made a name for themselves by providing the Azenis as a hot tire that just barely meets their definition of a street tire. I'd heard there was a new one, but I hadn't seen it before.
