My intention is to ride these tires until they are no longer usable, but then I will need to find replacements.

I've noticed in the lower priced tires, are Vittoria Zaffiro and Continental Ultra Sport II, both available as 28-630 size. There might not be enough frame clearance for 32-630, and I'm not sure how big a tire I can put on the skinny rim.

Are there any opinions about which tire might be nicer? Answers could be based on experience with one or both tires, or general impressions of the quality of the two brands. This is an N+1 bike, that I use for commuting and just riding around around town, typically solo, never competitive.
