do a lot of you use ARMADILLO ALL CONDITION tires here? they are awesome tires & are supposed to be very flat resistant. i just installed a set of these on my road bike. they are 27 x 1 1/4. the tire pressures are as follows on the tire: 115 minimum, & 125 maximum. is it critical that i maintain such a high pressure? i mean, will the tires be damaged if i ride them underflated? the last thing i want to do is damage these expensive kevlar lined tires. when i inflate them at half that pressure they are still pretty firm & i wonder why they have to be inflated so high. since bike tires seem top lose air when not in use, i would imagine that it will be a task to keep up that high pressure all the time & they will be frequently used underflated...
