I have also had difficulty checking tire pressures, often cutting myself on the openings to get to the valve stem. I found an easy solution in a hex drive handle with a magnetic socket that fits the valve caps. Easy to spin the caps off, they stay in the wrench end and are easy to put back on. A job that used to take several minutes is now about 30 seconds.
Another excellent solution to the difficulty in removing the valve caps is to use air-through caps which do not need to be removed to check or adjust the pressure. The ones I have are Alligator brand, made in Germany, and are very well constructed and work nicely. They have a sort of pushrod mechanism that actuates the tire valve only when a chuck is on the cap, so there's no additional danger of air leakage.
