Those miniature aluminum bats from Peterbilt for checking tires are the shnitz...

If Ram had two of them, he could go "bats akimbo".

That whole nitrogen thing is a scam, Jack. Think about it... the air we breathe is already 78% nitrogen, so how much are you really adding? Consumer reports did a study and found - over one year - the tire with air lost 1.1 psi of pressure more than the tire with nitrogen. Negligible over a 1 year period and if you check your tire pressure once a month... not worth the $5 per tire or whatever they charge for nitrogen.

Me? I never check it. I have TPMS... so the car tells me when the tire needs air. LOL! :-"

We knew about the PMS thing.........just not sure what it has to do with the tires on your car.However that does explain those hot pink seats.

TIRE PRESSURE MONITORING SYSTEM

I had my car filled up with Nitrogen a couple of years ago (I did not pay for it). I gotta say when the winter came i didn't have to adjust the preasure at all. Pretty cool. Now would I pay for it to save adding air NOPE... But it does work.

Now you live in California, and I now live in Florida so it really doesnt have the same benefit. But if your in a climate with big tempature swings it may be worth the $20 not to have to deal with it.

Yeah my TPMS went off so I gotta check on my tires after work. I hate warning lights cuz' I always thing it'll end up being something worse than it is. So I should check more often.

For $20 each re-inflation, it can be about whatever you want it to be!

I see you learned your broken English on the streets of Olongapo as well.LOL
