From everything I have read there all good. Most buy run flat for that extract security. I don't think there is one better then the other. If its something you like buy it.
Your hard part will be finding aftermarket shop that will mount it. Then you have to decide what air to run. There is a some that run 32 psi all the way to 40 psi. I run 40 and have even tread wear from one side to the other.
Yes you can still scrape the boards but not scraping doesn't make you less of a rider.
