Something else we didn't know:
When you get new tires, some providers don't have a spindle big enough to spin the tires for weight balancing. Instead, they use balancing compound ( essentially a bag of very fine sand ). That's OK, but not if they don't replace your valves or/and valve stems with new ones that have filters. Through rotation, the sand can get into your valve stem springs & seals. Worse, when you use an air gauge, the very fine sand gets sucked up even further into the valve stem and cause your tires to lose air slowly.
I checked my air pressure and twenty four hours later had lost significant air pressure in 7 of 8 tires. Luckily, my road side assistance was close by and two hours later I was on the road with new valve stems.
The tech said he is frequently called to Prevosts & Newell's with this problem. He also recommended spraying your tire valves with very soapy water to check for slow leaks. He also said to get valve caps that have balancing compound on the caps so the next tire change they should really clean the rims so that you will get good bead seals.
