Unless you weigh 140 or something your tire pressures sound very low. I pump mine up to the max allowed, although I may let the front be softer by 10 psi.

So for 23mm tires I was using 120 psi, and for my current 25mm tires, I inflate to 110 psi (which is the max on the sidewall)

Nobody WANTS to repair a tube on the road but the surest way to HAVE to is to not have what you need to fix your situation.
