2002 Avelon. bought used at Boch new to you. They mounted 4 new tires. I've had the same problem before with used cars where I have slow leaks... Tire specialist near my work wants to remount the tires after cleaning the rims. he showed me the machine he has that scrubs/grinds the bead area of the rim clean. he also seals the rim and then fills them with nitrogen. He will do all 4 tires for $160.
Does this sound like a good idea? Is the price right? I never heard of using nitrogen????
He was quite upset that the dealer mounted such poor quality tires on an Avalon but the are new and I'm not going to buy new ones I just dont want to deal with putting air in every week....
$160 sounds high to me. I would go back to Boch and ask them to fix the slow leaks, using a generous coating of bead sealer on the inside of the wheels. I used to call on them, and they had a good service department at that time.
Nitrogen is becoming more common to fill tires. It supposedly leaks out more slowly.
As Joe says be careful "grinding" rims - we've had 3 Avalons and all had had aluminum alloy wheels..
Costco does mount/balance/rotate/fill with Nitrogen for $16.00 tire if you are a member and didn't buy them there. I've never had a tire leak at the bead that was properly installed and any decent tech will clean it properly before installing Ron
Ernie is quite the character - he also happens to be the Subaru distributor in New England. He used to joke that he wouldn't retire until he was a billionaire, and our guess was that he was about 3 quarters of the way there. His local house was an unassuming raised ranch, although he had the requisite mansion on the vinyard were he spent weekends.
Not only that, but you could open the valve cores slightly and use a remote igniter for a JATO assist over that pesky overpass or rush hour traffic. That might become trendy and popular with the discriminating young pimp-my-ride crowd.
In an ironic universe, possibly. H should leak faster than any other gas, thanks its atoms being the smallest. I'd expect this to hold even for its heaviest isotope, Tritium.
Anecdote: in the 1960s (maybe 70s), there was a deep-sea-living experiment that involved a habitat anchored to the sea bed. It had everything needed for a reasonably comfortable modern life, including a normal TV set. Occupants could only come and go by diving, using high pressure breathing gear supplying a mix with hydrogen in it, a mix also employed in the habitat. The TV set CRT display eventually became useless, as hydrogen atoms leaked through the CRT glass under pressure and spoiled the vacuum.
Say again? AFAIK they've never used a Hydrogen and Oxygen blend for diving, if for no other reason than the extreme fire and explosion hazard...
Helium and Oxygen diving breathing mixes however have long been used with relative safety. And Helium would easily sneak into a CRT, too, since it's a really slippery molecule.
