So I knew one of my tires needed air. Normally I'd just add air at work but I've been off work, holidays plus flu. Because still wiped out from flu, asked him to put air in the tire. Here's where the smart part comes in. He opened the car door, stuck his head in and asked me what pressure. On the other hand he probably would have kept driving on a low tire if I hadn't said something. :/

Speaking of tires, his car has nitrogen filled tires. I'm contemplating just adding air to them and then no more hassle of tracking down nitrogen to top them off. My work doesn't have nitrogen. We really should get some. We get plenty of cars with nitrogen filled tires. What are your thoughts, oh wise opponuts?

It's a 1999 Lexus RX300.
