Checking Spare tire Air
My 08 Yaris spare tire air valve is mounted upside down in order to check air have to remove tire from its well. Brilliant Toyota design. Came across "Chek A Spare" its a hose that attaches to the spare tire valve & other end can be sticking out any spot in the rear so now to check spare air all i have to do is open the hatch. Works great for my 08 RAV as don't have to remove the hard cover anymore. Great for pick ups where the tire is mounted underneath no more groveling on the ground to check truck spare air.
www.getaguage.com Other sites carry it also. Goggle it in. Was $6.00 ordered 2. Shipping is a pain but what can you do. May be some local stores carry it but none in my immediate area did. |

it is far more likely a spare will go flat with one of those widgets attached,
than just keep the spare in place left alone. they are nice extensions though. http://www.getagauge.com/ |

Thats why you check the air once a week to see if any leakage or nails. So far haven't had any problems with the Chek A Spare in 2 cars.

At least every 20 years, whether it needs it or not.

Just under 20# would have turned on the TPS if there was one. & guess what my spare did have a small brad in it i noticed it when i put it back after using it for a flat replacement, was a small leak i fixed it with my handy nail kit. You got a problem with the Chek A Spare hose very simple don't buy it. Its been great for this old guy. Now i check my spare air once a week when i do the other tires before that i didn't, just waited till the TPS light came on.

It's easier to buy a small portable air compressor and kit it in your trunk. That way if your spare tire is not aired up when you need it, you can fill it up on the spot. Plus it's good to have one anyways. |

I think checking the air int he spare is a little obsesive. Maybe once every other month or so. You loose about a pound on adverage. I think the spare tire is supose to be set at 60psi. Mine was at 30ish last time i checked set from the factory. So even if you dont add air in a year. You would still be at about 50 which is still okay to drive on.
Or better yet find a place to fill it with nitrogen. Its denser and leaks out even slower. Maybe would take 2-3 years to loose 10 pounds.

Do you lube your scissor jack every week as well? Hate to have a sticky jack AND low air in the spare..

Great idea! These compressors also have a light and flashing light built into the unit for emergencies.

Carrying a compressor is a good idea.
It's false that nitrogen is denser than air. It's a little less dense. Gases' densities are directly proportional to their molecular weights. Air (dry) is approximately 78% nitrogen, around 21% oxygen, with various trace gases making up the rest. Oxygen's molecular weight is about 32, nitrogen's 28, so air with its oxygen content is a little denser than nitrogen. I doubt you could measure a significant difference in the leakage rate. Nitrogen's a current "snake oil" fad for the most part. |
