Bob Newhart did indeed portray Proton, around ten years ago. ---

> [@Purebred](#): > > Bob Newhart is Mr Wizard? “Mr. Wizard” was the television persona of Don Herbert, a pioneering science educator who hosted popular children’s science shows from the 1950s to the 1990s. In this photo from the 1950s, Mr. Wizard is demonstrating that even Balloons are “repelled” by the idea that Balloons could possibly get larger by the osmosis of Oxygen through the semipermeable membrane of the balloon rubber… ![wiz](https://global.discourse-cdn.com/cartalk/original/3X/e/6/e6556eb4fe5c38cd7a7c9ef8860052b8397f4cff.jpeg) ---

CU used only two tires, One for Air and One for Nitrogen… Only one tire for each… Kicking the tire to ensure proper inflation is about as scientific… Did they even check to see if the tires came from the same lot? They should have had ten or more for air and the same number for nitrogen… This is one test that I would not be confident in the results… ---

> [@LoudThunder](#): > > CU used only two tires, One for Air and One for Nitrogen… The article said they used 31 models of tires, and inflated one of each model with nitrogen and one of each model with air. So I take that to mean 62 tires total, all different models of tires. Either way, the end results were insignificant. Over a year the air tires lost 3.5 psi and the nitrogen tires lost 2.2 psi, a difference of 1.3 psi. I could grab 10 different gauges and come up with a larger difference in readings. A 1.3 psi difference in tire pressure is not meaningful. As far as I’m concerned, the argument for using nitrogen in tires doesn’t hold air. 😀 ---

If tires pressure loss is only 3.5 psi/year, then few vehicles should have a low tire pressure warning light on. Vehicles are serviced every 6 months and half of them have a warning light on. ---

Maybe because they referenced the Philippines? Maybe we need a thread on the most dangerous roads in the world. I imagine they would all be in Asia and South America. ---

You might have noticed that I posted that I “did not think it was harmful…” It is not a matter that it is innocuous _(Warning… Big Word - Meaning things that are safe, inoffensive, or unthreatening);_ but I fell “victim” to the download so I ran it through Norton and McAfee Anti-Virus to be safe… But the next time someone posts a link that downloads, it might not be safe… And for the record, files that end in “PDF”, "DOC, and “EXE” are some of the most notorious files to open from unknown sources… [Previous page](https://community.cartalk.com/t/california-s-proposed-new-tire-regulations/205562.md?page=5)
