Actually, that's not what I said. I said, while performing weekly tire pressure checks on our fleet of large trucks (nitrogen filled) and small trucks (air compressor filled) I don't perceive a difference in their readings. I didn't say anything about temperature variations. Warm tires have increased pressure. Inreases in pressure are not a real issue for someone looking for economy. However, decreases are another thing all together. My point is, if you check your pressure regularly. Save your money and just use air...dry air.
