Are you referring to the Race Lite or the Race Lite Hardcase? I have the latter.
After putting three and a half thousand miles on a set without one single flat, even after numerous times rolling over fields of glass, I must say that I like them very much.
They're not svelte racing tires (despite the name), but a Trek Hybrid is not a svelte racing bike. They're not sluggish feeling at 85-95 PSI which is where I like them, they have very good traction in the wet, and they're quite durable.
Two to four miles is pretty short commute, and race tires aren't going to make a relatively heavy bike climb like a mountain goat. If your fitness level is up to snuff, the only thing else that is going to help you is buying a lighter road bike. I'm not saying that you should buy a different bike, I'm saying you shouldn't worry about the tires until you wear them out.
