ProLine Inversions would be a good tread, and in fact I bet they will offer a ton of grip on tarmac... just no tread life at all since they are only available in ProLine's softest compounds
Probably then the question is also: Where do you want to be with grip and tread life? You can get tons of grip with softer compounds and in fact in that case many tires with pins work great, albeit especially the latter only last for a very short period of time. And should it be purely tarmac, or a bit of an allrounder? (In which case Schumacher blocks might be worth looking at).
