D55 vs. WRS-2

[racecrazy2]

Is the only difference between these two is that the wrs is grooved up more??

Is the D55 more a slick track tire and the wrs a tacky track condition tire??

any info would be much appreciated.

the wrs 2 is on a rib casing also (sidewalls more flexible )

[Egoracing]

Different sidewall, different tread cut but the rubber is the same, they are both 55 series compound. The WRS fires sooner and corners better than even a cut D55.

Still a throw away tire!! IMO!!

SO a wrs cut like a wrs-2 should be a faster tire? So should it be siped up also or will it blister?
