Ingersoll Rand claims that there are several distinct advantages to filling your tires with Nitrogen:
* Better air pressure retention -- Nitrogen doesn't seep out through the tire walls like Oxygen can, so tires remain fully inflated longer.
* Enhanced fuel economy -- Nitrogen dissipates heat faster than air, and heat causes rolling resistance. "Maintaining tire pressure can boost fuel economy by as much as 6 percent."
* Longer tread life -- Filling your tires with pure Nitrogen makes tires run cooler, which will reduce tire failure. It also prevents oxidation, which can cause tread separation and belt failure. Since Nitrogen doesn't carry moisture, it won't cause rust on the inside of rims and valve stems.
* Slow chemical aging -- "Filling a tire with Nitrogen also significantly slows the chemical aging process of the tire's rubber components."

I read the article referenced above. It's interesting; I recommend it. Note that the writer reaches this conclusion:
Save your money, and keep your tires properly inflated with air. You'll get much better results investing in a small compressor for your garage and keeping your SUV tires properly inflated with air.
He goes on to suggest:
If your local tire shop has a Nitrogen Tire Inflation System, see if you can get them to include a free fill-up with Nitrogen when you buy your next new set of tires, and try it on for size. Do some real-world tests and join the debate.
A substantial engineering discussion is available at Eng -Tip Forums. You can also read Click and Clack's brief comments here.
Does Ingersoll Rand make Nitrogen and / or related equipment? Gee, I wonder why they would recommend it...
* Better air pressure retention -- Nitrogen doesn't seep out through the tire walls like Oxygen can, so tires remain fully inflated longer.
I thought air escapes through the tire-to-rim microscopic seal cracks and the valves...
* Enhanced fuel economy -- Nitrogen dissipates heat faster than air, and heat causes rolling resistance. "Maintaining tire pressure can boost fuel economy by as much as 6 percent."
Dissipates heat? The heat is dissipated OUTSIDE the tire, not inside of it. The heat on the inside stays on the inside with the exception of rims acting as heat conductors. I would bet that there is very little difference in heat conductivity between air (78% Nitrogen) and pure Nitrogen.
* Longer tread life -- Filling your tires with pure Nitrogen makes tires run cooler, which will reduce tire failure. It also prevents oxidation, which can cause tread separation and belt failure. Since Nitrogen doesn't carry moisture, it won't cause rust on the inside of rims and valve stems.
Again with the cooler tires... Moisture? Oxidation? Are you kidding me? Ever see the inside of a tire after 50,000 miles? It always looks brand new. There's no oxidation or moisture inside the tire. Tire degradation due to elements occurs only on the outside. Also, I have never seen rust on the inside of a rim.
* Slow chemical aging -- "Filling a tire with Nitrogen also significantly slows the chemical aging process of the tire's rubber components."
Again - the tire doesn't age on the inside, only on the outside.
Conclusion... Let's all fill out tires with Nitrogen, strap on those fuel-saver magnets, dump Marvel Mystery oil into our engines, and watch our cars last forever while improving MPG by 80%...
Result: winter or summer pressure is constant therefore the tire grips the road surface as intended and treadlife is prolonged.

Not so. Nitrogen is not immune to the laws of physics. But use it if you want to -- it won't hurt your B9's tires.
not to sound defensive of the B9... but I think all vehicles in your condition without warming up the car and wipers would respond the same. the rear defroster is not that strong but that has been mentioned before but it does work if you give it time before driving off.
Yet I have never seen or driven this car.
Yes, my husband picked up the car with good intentions of meeting me in another state and he wrecked it. Only 2 days after he signed the paperwork.
Here is the latest update:
It took forever to get the car towed from Georgia back to Florida. Finally after 2 or 3 weeks, the body shop here received it and estimated the damage to the outside at $7,000K. I don't know what the inside damage was. They said it will take a month for it to be fixed.
So I'm thinking perhaps mid-to the end of February, I will see and drive my new car!
Meanwhile, I extended my lease one more month on my current car as I need to turn it in and now my insurance company doesn't want to reimburse me for this month. It's not considered a "rental". So I guess I need to fight it or just turn in my car and get a rental so I can get reimbursed.
Take care!
Though I got a rental Taurus when my Miata went to the body shop, and that car was awful. Smelled like an ash tray. :mad:

Has anyone tried to install a Winter Style Wiper Blade under the b9 wiper cover? Just figure I would learn from someone who has done this already.
Also anyone change the rear wiper blade. I would hopefully be able to change the whole blade instead of having to change the rubber insert.
thanks
If you look at the base of the arm, at the end of it there is a hook. So to remove the blade, you actually have to push it in towards the base. Usually there is a locking clip that you have to push it so that it'll slide out, though.
Sounds weird, I know. Found a pic that shows it:

The J hook is a pretty common setup on Asian vehicles.
To remove the fronts, there is a slide lock that moves when you squeeze the release tabs on the sides. Once it slides to the unlocked position, you rotate the blade just like the rear.

So if you put aftermarket full replacement blades on I can't see how it will fit. I see the rear blade is like other cars I have had. you need to have a replacement blade with a larger opening as the arm doesn't lift fully off the glass like Kuoh mentions. so with out the larger opening you can not get the aftermarket full replacement blades on.
I think I will just end up buying replacement Rubber and just replace the wiper inserts.
the 16 inch (I had to cut to 14" for the rear) and reuse the metal inserts from the factory blade. that was a pain to install as you need to work it between the two unmovable stoppers on each end of the blade itself...
took about 20 mins to do all 3 blades. thanks from kuoh about how to remove the rear blade. I thought the same thing this is going to break ... but yepp just flip it around and push until it pops off. I see there is NO way you can install an aftermarket 14" blade in the rear and make it work with the arm. I had an old 14" winter blade I used on my Pacifica before and it would not fit with any of the adapters that came with it. :mad:
As for the installing the rear refill, the easiest way I found was to insert it from the middle towards one side. Once that side hits the stop, pull the tip out a few inches until there is enough clearance to insert the other end from the middle, then work it all back in. That way, you won't be trying to pull an entire insert over the stop from one end to the other. It is still a PITA design however.
I ordered OEM replacements from subaruparts.com for about $20 total, so no cutting down was necessary. Probably would've been cheaper to go the generic route like you, but I didn't want any unexpected hassles. Also, the included instructions helped to figure out how to get everything apart.

In the case of tires, the volume is the same so the above equation becomes P1/T1=P2/T2. So if you have an increase in temperature, (T2 goes up), presure (p2) will goes up. And if you have an decrease in temperature, (T2 goes down), presure (p2) will goes down.
Also , I was told this by someone else - give me a break.

I recently broke in my Tribeca in several inches of fresh snow, and I thought she did great! I could barely even get the tires to spin - I had to try to do it. I'm proud of how she performed.
Thanks
If anyone takes it to the dealer and gets a resolution please let us know the outcome so we can "steer" our dealers in the right direction.
i definitely hate the goodyear all seasons that came on the tribeca, no traction in snow! hopefully the 07s have better tires.
with your towing package you have the tranny cooler, correct? Maybe that is what I need but I sure would like Subaru to tell me that.(and supply it)
just curious if anyone of you guys had accidentally driven your tribeca with the emergency brake on and what effects does or will have on the vehicle.
my wife had informed me that she had driven it about 10km at 40-50km/h before she noticed the red light on.
thanks,

It doesn't care if it's warmed up or cold.
It started at about 9000 miles.
It only does it when I start out slowly to keep gas consumption down.
If I give it more gas out of the hole, like merging onto a highway, I don't get the shudder.

Does the brake hold the car if it's in neutral? You're probably OK. At least it will not affect the rear disc brakes at all.

For other reasons I will probably be opting for a 2004 Lexus 470, otherwise this years Beca would be my choice - can't stand the design of the '08.
