    I have electric pump. Only goes to 125. I run close to that. Clip loses air when really high. I hold it with my hand. You will begin to see change in performance and the strength required by yourself to push chair the lower you run the pressure. Higher pressure will give you better performance but "bumpier" ride. Lower pressure will give smother ride but lower the pressure the greater the loss of performance. It is your decision.
    Perfect summary! I spoke to Spinergy (wheel people) customer service about pressure on MPEs, and they recommended 95-115PSI depending on compromise of smooth ride and efficient propulsion.

      I figure the closer they are to the max the faster the molecules are going to find their way to leak out, so I don't bother to get over 120 even with a power pump. It is time to add air when my brakes start to slip.
      I have had periodic paralysis all my life. I lost my ability to walk in 2011 beginning with a spinal block, which was used for a hip fracture caused by periodic paralysis.

        Going at 140 - 145 for the last 5 years. Most of my day is on concrete and office floors so I really like them to be firm. I try to top them off every week. Pushing on them does not give me a good sense of what has been lost or if they have gone way below 145.

          Really I love the high pressure. Those tires are fantastic then. Here is an example. The in grocery store, the very high pressure, I can give 1 push at beginning of aisle and sale all the way to the end. With the lower pressure, the same aisle requires multiple pushes to go the length of the aisle. Need remember though, grocery store surface is smooth and flat.

            Tires are going to shop. Decided no fart around. I have the tools, but really never changed tires. Was surprised how still the MPEs are. Plus really no sidewall for and flex.

            In my youth, I was an avid bicyclist, and learned a lot. Now I change my own tires with a valve wrench, tire irons (edit: three bare-metal tire irons), and a floor pump with gauge. I run 559 MagicWheels.

            I even changed a flat on my AeroZ while away from home awhile back. I always carry tools, extra tubes, and a CO2 inflater.

            Pneumatic tires are easy to change with the right tools and know-how (edit: and sufficient hand function). The most common nube error is a pinched tube. If you've never changed a bike tire before, pay a bike shop to do it, and ask to watch and learn. Then the first time you try it yourself, have extra tubes. You're quite likely to pinch a few.

            One technique I always use includes removing valve stems from new tubes before mounting them. After mounting tire and tube fully on wheel, inflate each tube almost full; when you remove the hose, the tire deflates, and wrinkles (future leaks) are gone. Reinsert valve stems, and inflate to desired pressure. Always use quality rim tape over spoke heads. If you're running high pressure tires (like Schwalbe MPEs), use quality tubes, too.

              I leave my air compressor running when I flip valve to take off. That sort of reduces pressure loss. Compressor I have, when it gets around 110 psi I am not sure if it struggles or what, but the rate at which the pressure increases significantly slows. I did check for leaks. There are none of that.

                I went back to 140psi; 115 is too sluggish for me.

                  Shop set mine at 140. I think that is great. Just now wish my pump went that high. New tires are like glue. And new tires really draw wonderful creative artwork all over hardwood floor.
