So what you are actually asking is. Which would be the best tyre choice to use of a smooth concrete surface to get the most grip? Correct me if am wrong in saying that. Well from what i know, dirt hawg tyres work good on tarmac. and also the kit tryes, i think they are block-head, but i am not so sure on slippery concrete. Maybe mipin tyres would work better as they are what most people use in-door on slippery sports hall surfaces. But other than that i am not really sure.
Hope this helps a bit.
