Once a driver is in the habit of checking tire air pressure regularly, his next goal should be to determine the optimum pressure required for his operation. “Considering the old saying that time is money, the time saved by not inspecting the tires, about 20 to 30 minutes, with a gauge but rather with a thump will be more than lost in the monetary terms of irregular wear, reduced wear life and even losing the tire if the air loss is caused by a puncture,” Estupinan says. Getting in the habit of putting a gauge on a value stem can be a tough adjustment for busy truckers. If it differs from that on the master gauge, use the calibrated gauge’s adjustment screw to adjust its pressure reading to match the master gauge. For help locating a dealer with a master gauge, contact the Retread Tire Organization toll-free at 88 for a packet of information on how and where to buy calibrated gauges and how and where to check their accuracy. Most tire stores have master gauges and will let truck drivers check their calibrated gauges against it for free, which beats buying a master gauge for as much as $100. A calibrated gauge will cost about twice as much as a lower-quality $10 gauge. ![]() “That’s not to mention factors like irregular wear, higher thermal and mechanical fatigue of the casing, lower retreadability and even premature failure,” Estupinan says. Running at 40 percent underinflation will reduce tire life by 50 percent.Running a tire constantly underinflated by 20 percent will reduce tread life by 30 percent.While that might seem low, it adds up when considering tire positions and miles run per year. For every 10 percent of underinflation, a 1 percent reduction in fuel economy will occur.A difference of only 10 percent in air pressure between duals can cause enough variation in diameter to produce irregular wear in both tires.“And the typical sound of a tire at a particular pressure will be different if the tire is hotter.” Running tires under-inflated by only 10 percent can reduce fuel economy by 1 percent.įurthermore, Estupinan says, it doesn’t take much variation from optimal pressure to produce serious problems. and be legal.“If you think you have a ‘well-calibrated’ ear, thumping the tires could possibly give you an idea of the difference in pressure between one tire and the other, but it will never tell you the actual air pressure,” he says. Work as well as any billy club or baton I"ve seen. Or, for whatever situation you might find yourself in and want it for. which work perfectly, if and when needed and someone wants to make a forced entry into the car. It's been argued and cases made, that a baseball bat was being carried as a weapon, not because they were headed to a baseball practice.īut, they never say a thing about those small (2 ft) "souvenir bats". Here, it's illegal to carry / have a club in your car. ![]() If things got started, it was the first thing I grabbed. grab the one end and could use it like a hammer, or slide you hand thru the other side. ![]() Well, a few places we played (only because we got paid well) where there were always fights to near riots. It also popped right out, for when you were packing it up. It was portable organ that had a piece that came down underneath in which you used your knee to move it. I played saxophone, organ, bass and guitar in bands. ![]()
