    Wire tyres have a steel wire bead (the bit that sits in the rim). These are heavier and cheaper. The tyre can't be folded. Folding tyres usually have a kevlar, aramid or similar bead which is flexible, lighter and more expensive, and the tyres can be folded which is convenient for carrying a spare (probably only necessary if you're touring). Folding tyres may well be easier to fit (get on the rim), though the floppyness may add an extra challenge to fitting, albeit a small one. I prefer folders because I would like to save the extra few grammes.
