It’s a good day to check your car tire pressures. Mine were in need of air, all around. I see some vehicles driving on tires that are obviously under-inflated, large vehicles, Tahoe’s et al, vehicles that because of being top heavy really can get wobbly with low pressures. The new tires often mask low tire pressure by their shape. I have a tire gauge, they are cheap and better than using most air pump gauges. If you think close enough is good enough you are wrong and be advised a under-inflated tire wears out faster. The Mobil on Epping Rd has a fairly accurate gauge on it’s air pump. The Mobil on Portsmouth at Walgreens does not have a working gauge. If you  purchase gas the attendant can turn on the air pump remotely, you piker. No, really you should ask and save a dollar.
