Got a question, where do you get nitrogen? They have at gas stations?kanji said:may i suggest using nitrogen to fill your tire? Costco fills their tires with Nitrogen, and nitrogen is larger molecule than standard air. So you don't have to fill when you change altitude or when it gets cold or hot.
You normally lose about 1 pound per month and 1 pound per 10 degree drop (pressure will increase when temp rises by same amount). Are your tires cold when you check them AND fill them? If you fill them hot, i.e. after driving to the gas station, but check them cold, then it will appear you've lost more than you actually have.Zlash said:Seems i have to air up a tire about once a month that's lost about 7 psi. I check them all the other day and they were all below 30...is it normal to lose that much and I just never noticed before TPMS?
As i mentioned Costco fills their tires with nitrogen and make sure you specify to them @ what psi you want on the tires. If you don't have a Costco near you, any Aeronotics shop can help you out, most planes or large commercial planes uses Nitrogen to fill their tires with air.Tex's Ridge said:Got a question, where do you get nitrogen?
