Can't speak for the 16" Kenda's but our Sun EZ3-USX came with a 20"
Kenda. When one got a flat, I was happy to replace it with a Marathon
because the Kenda was limited to 65PSI.

I recently bought 2 of the new kevlar versions of the Scorchers, and
that's the only version I expect to buy from now on. Kevlar costs a
bit more, but is usually more resistant to flats and able to handle
higher pressure.

In addition, I've now bought a thorn-resistant tube for the next time
I need a tube, as I really dislike tire failures on the road.

(Another alternative possibly worth considering might be the new
Marathon Plus tires, because they are supposedly even more resistant
to flats.)
