Well as the wheel rolls on!
Coming home today our ET just did not fill right Like a flat tire!.
so we were the tire shop & pulled in to have it checked out?
As it has gone before the Dealer (said) We put Nitrogen in all Huyndai's!
well the tire shop checked the tires & said the tire light came on becouse of low air in them- it was at 25 lbs &26 for the high one, that is why the light came on ! They should be 32lbs. I said we have Nitrogen in the tires & should that not happen??
Well the dealer got you he said there are no green caps & there is no way to be sure if they did put it in??
He filled up the tires & all is (ok)

 

Ron: Green caps=Nitrogen filled? News to me and do not know if it is good news. I have green caps.

 

What is the weather like where you live? As in the temperature? Tires will drop 1-psi in pressure for every 10-deg F (5-deg C) drop in temperature. So if it's in the 30's F (like it is here) and the last time you check the tires it was in the 80's F (summer time), that's a 50-deg F drop and would cause a 5-psi drop in pressure (32 - 5 = 27-psi). It's not a loss of air, it's a drop in pressure because pressure and temps are related.

That is correct. Green caps means the tires are filled with nitrogen.

FYI, you get little to no benefit with nitrogen on a street car. Don't waste your money on nitrogen. "Regular air" is 78% nitrogen already. If you can get nitrogen for free, then go ahead but don't pay for it. It's wasted money.

That is what I was thinking, thanks for the input!
I don't know what they charge up it ont cheep, & my caps are silver in color.
& the coldest it has been is 47% with a high of 70%.
with the tires at 25 psi, I'll pass that 78% on to my Dealer??
& not pay for it anyway.
Thanks again
Ron
