Are 22mm tires too thin for commuting? I recently switched from a mountain bike to a road bike with 22mm tires for commuting. 

I noticed right away that I could not do the things like hop over curbs with this new bike. I also got flats. Lots of flats. I would get 1 flat per week, and I got good at patching tires. After a few weeks of this i got Tuffy tire liners and haven't gotten a flat since. I patched up all holes in my tires from inside before putting them in (and they were a pain to put in).

I still have the following fears:


If I am going fast and I hit a small (less then 3" bump), I might get a pinch flat.
I cannot ride off a curb onto the payment without wrecking my bike.
I cannot hop curbs.
I must check my tires after every ride for glass lodged in them and take it out with tweezers.
If there is a sizeable hole (from glass) in my tire, I must use a patch kit to patch it up.
I must always ride at 120psi per tire (I weigh ~200lbs).
My stopping power compared to the mountain bike is really really bad (especially in the rain).
I must pay extreme attention to the road and go around bumps.


Should I be worried about these concerns? Are 22mm tires too thin for commuting?

Followup:

Well, after about 2 months of daily commuting on the road bike I have this to say in the defense of my earlier self:

My biggest issues turned out to be:


My bike lock which I used to attach to my bike created a lot of vibration which in turn made it impossible for me to hear any noise my bike was making. One time I rode on a flat for a few minutes because I couldn't hear/tell it was there because of the vibration/noise. This incident made me think that flats on a road bike were undetectable.
I rode clipless which scared me in traffic. 


I've since started to carry my bike lock in my backpack so now I can hear my bike. I've also replaced my awesome clipless pedals with regular ones which made me feel much more comfortable in high traffic. Not fearing death actually made me faster with regular pedals in the city.

Commuting on the road bike is a blast. I love passing everyone, and now that I figured out how to properly use both brakes, I can actually stop almost as quickly as I could on my fat tired mountain bike.
Most of your fears are unfounded or way overblown.


  If I am going fast and I hit a small (less then 3" bump) I might get a pinch flat.


Pinch flats do not occur on tires that are properly inflated.


  I cannot not ride off a curb on to the payment and not wreck my bike.


I do this on both my commuter and my racing bike. Just do it gently and not violently.


  I cannot hop curbs.


I do this at slow speeds with no problem.


  I must check my tires after every ride for glass lodged in them and take it out with tweezers.


Easier is to just not ride through glass. I've never had to pick glass out of my tires after three years of commuting by bike.


  If there is a sizable hole (from glass) in my tire I must use a patch kit to patch it up.


Yeah. But again, you shouldn't be flatting this often. I made it 6,500mi on my last pair of tires.


  I must always ride at 120psi per tire (I weigh ~200lbs).


Ride at whatever the printed range is on the tire itself. Some road tires are fine at 85psi. Usually this involves topping up air once every week (for 120+psi tires) or two to three weeks (for 85psi tires).


  My stopping power compared to the mountain bike is really really bad (especially in the rain).


Your front brake should be more than capable of hurtling you over the handlebars if slammed shut at speed. Braking power will be significantly impacted in the rain, however.


  I must pay extreme attention to the road and go around bumps.


Way overblown. Don't go plowing into 5-inch potholes, sure.

If you're having this many problems, you're probably treating your road bike like a mountain bike (why are you having to hop curbs so often — it's a road bike, not a sidewalk bike) and you probably have worn out and/or bargain bin tires. Get some decent tires with puncture protection and chill out a bit.
