actually you should fill them with helium so your car will weigh less . . .


Then they would explode!!!

Makes sense now ... all those kids with Mickey balloons at Disney World are actually suicide bombers and the guy selling them: an arms dealer . . .

I knew something wasn't right about the whole thing . . .

 

Hydrogen is flammable, helium is inert.

 

I own 4 cars and a motorcycle.I am in the compressed gas industry with free access to nitrogen ,and run good old air. Nuff said,save your money!!

 

Or fill with nitrous oxide,make your tires happy happy!!

 

We have a machine at work (shop). It does 4 tires at once - which is the nice part, you set (pressure) it and forget it, walk away, it does two purge cycles and then a final fill. That's its biggest advantage to me, is it just makes setting TP easier and quicker.

As for the benefits - I will say that it seems that the full shot of nitrogen seems to last longer in the tires. I'll go almost a full year without any meaningful pressure loss. (I swap off winter/summer tires..).

As for paying for it, no way.. I like Costco's model, give it away.
