Run flats are 350$ each low profile

Especially the people that drive on the low (nearly no) profile tires. They may look "cool" but not for me

It's a give and take, run low pressures and risk getting flats and bad MPG, air up to max, great MPG which really adds up in 40k miles, choose what's important to you

Be careful running tires at max air pressure , on the GB doing 75mph on a 105 degree day a blowout is bad , just saying

I would suggest an *accurate* mechanical gauge.
I don't trust 90%+ by the register.

I have an app on my phone that I can pretty much see all the stats for my car. Psi, oil levels, etc. it definitely comes in handy.

I tell you i'm scared to death with all the stuff they put in cars now. I just prefer the old fashion dash of 20+ years ago. Aftermarket stereo is an exception.

Yup. Good mile and bald center with max pressure.
Flip side, great traction in sand with low.
Depends what the situation is.

It's one of the major advantages of nitrogen, and why aircraft and race cars use nitrogen in their tires. Due to the lack of moisture, the pressure is much more stable with temperature shifts.

rexdutchman · 10-24-2018, 08:30 AM

Yeah but that Nitrogen in car truck tire is a rip off 78% of air IS Nitrogen , Plane and NASCAR very different
PS a good shop will have dryers on the air supply.

How is it a rip off? A lot of places offer it as a free service if you buy their tires. Refills take time, but you can always top off with regular air if you have to.

I see most tire shops switching to nitrogen in the next few years.

I own a professional gauge and all of the ones sold at the register are junk, don't waste your money on those

Max manufacturer suggested pressure will not make the middle go bald, tires don't turn into egg shape, it will give you a slightly rougher ride quality, low pressure can cause the sides to rub though

It has been shown in numerous tests that the nitrogen supply in shops is not pure enough to be of much if any benefit. Race teams and aircraft use lab grade systems so you are comparing apples to oranges.

I am a Technician w Toyota. Our TPMS systems have a minimum threshold ( when light comes on) of 26-28 psi. The light will flash when key is turned on if there is a fault in system. Full size spare will have sensor. Mini-spare does not.

Bottom line... if light is on on check your freaking tires!!! Note- factory tire pressure specs can be found on drivers door jamb or door edge of every car. Required by DOT.

Can you link to one of these tests? I've seen a noticeable benefit to having nitrogen. The first year I had nitrogen, I checked the tires every month, plus a few extra times, and the pressure only changed about 4 psi all year. That's incredible compared to what I was used to. I used to lose more pressure than that from a cold front coming through!

Tsmokies · 10-29-2018, 04:20 PM

4 psi a year is awesome crock. I try to check mine monthly and it's usually ok. 35 to 33 psi makes for a smooth ride and optimizes the tire life. Heck oil changes these days can be 7,000 miles plus depending on your oil change indicator. That's a lot of months for me to have my tires checked by the dealer.

I' would like to see those test results also kosey

BMW put out a Service Info bulletin SI B 30 04 06 basically saying it wasn't necessary. Continental Tire has same opinion http://www.continentaltire.com/news/...-right-my-tire. "Top Gear" did there own test and found little if any difference.

If you feel likes it works for you, use it. No harm

rexdutchman · 10-31-2018, 09:33 AM

^^ yes , and NASCAR uses because they have tanks of the air guns , and tires ( high pressure to run air gun and fill quick) Airplanes because doesn't expand at low outside pressures. I said before rip off for most , most places charge for the "service"

It's certainly not necessary. Air works just fine, especially if you check the tire pressure every few weeks (and more often during weather changes!). But the benefits of nitrogen, as shown in your link, are very real.

The fact that more dealerships and tire places are offering it for free is even more reason for you to use nitrogen. You'd be an idiot to turn it down if it was free with the purchase of four tires!
