I've just used standard road tires, and they've worked fine on my 4.5" Kreitlers. A small roller might be different. I have not seen the wear that is seen on a trainer for whatever reason. It might square the rear a little, but my rear tire was a little square to begin with, so it's hard to judge. I'm got plenty of roller hours, though, and it's not too big of a deal.

If I was going to get picky, I'd probably put some cheap Forte tires on, but honestly, it's a good place to kill tires that have one foot in the grave to begin with.
