What should I look for in a set of rollers?

Just toying with the idea of rollers for now. Confessing ignorance here and so I started with the generic, open ended question above.

One specific concern is tire wear. My understanding is that larger diameter rollers are easier on tires. Is this correct? Do I need different tires for riding rollers as opposed to the road?

I've no specific brand or model in mind but have looked at products like the TACX Galaxia, Sporcrafters Overdrive Pro and Kreitler 4.5 just to gather information. I like the idea of added resistance with the Sportcrafter's resistance roller or an accessory like the Kreitler headwind fan.

Note that I'm not interested in trainers at this time. I like the idea of balance, concentration, engaging the core, etc., and am not interested in zwift. I also ride fixed gear and so would prefer rollers over a trainer at this time.
