T5 LED grow lights are some of the greatest innovations in fluorescent technology. They have a lot of benefits over older T8 and T12 types of fluorescent lights, but many people still want to make the switch to LED lights without having to completely replace their lighting systems.
Pump It Up. Proper tire pressure lets your bike roll quickly, ride smoothly, and fend off flats. Narrow tires need more air pressure than wide ones: Road tires typically require 80 to 130 psi (pounds per square inch); mountain tires, 30 to 50 psi; and hybrid tires, 50 to 70 psi. To find your ideal pressure, start in the middle of these ranges, then factor in your body weight.
PSI is measured by the notches on a tire air pressure gauge or with a number reading on digital gauges. To find out what PSI is right for your tires, consult your owner's manual or the sticker on the driver's side door.When buying new tires, or getting a rotation, it's a good idea to ask what the ideal pressure is.o get a PSI reading on your tire, place the air pressure gauge onto the tire's valve stem, the pencil-width air nozzle on the side of the tire. Try to place the gauge evenly onto the valve stem.
