Call M/T ... The reason the radial PRO was design was for marginal tracks ... they took the feed back from the racers and designed a tire that just flat out works if you go to a track that is just not prepped at all yes you will have a problem.
I think I still have some shock tuning to do with mine, the few times it has spun on a marginal track it has hooked first then lost it shortly into the run.(I log driveshaft RPM so its easy to see)
