Warranty repair question - can I get the original part back ?

Re: Warranty repair question - can I get the original part back ?

they do not have it to save weight just like no power seat on the passenger side

OK
Now I get it.

Mark it's a Z06 just keep putting air into them until the tires stop rolling off the rims at 1 g cornering Yahooooooooo !!! You will have a sh.... load of fun in it Mark great purchase. Stewy

Don't the Z06's have automatic hatch closing mechanisms like my coupe?

They do now. Power pull down was added for 2009. Added about 3 pounds to the car.

You can also get a power passenger seat in a 2010 Z06. In an optional package.

44# is the max pressure to get the weight rating. check on the inside edge of you drivers door jam for the correct recommended pressure

Correct !!! If you have 44 in them, you are way over inflated. Put them all at 30 to 32 according to the monitor. Then see if your system corrects itself. It will. You may have to turn the car off and on then take it for a quick drive to make sure you have it right. If you have a place that offers a nitrogen fill, do it !!

GM's position on the use of Nitrogen Gas in tires from the service manual:

General Motors does not oppose the use of purified nitrogen as an inflation gas for tires. We expect the theoretical benefits to be reduced in practical use due to the lack of an existing infrastructure to continuously facilitate inflating tires with nearly pure nitrogen. Even occasional inflation with compressed atmospheric air will negate many of the theoretical benefits.

Given those theoretical benefits, practical limitations, and the robust design of GM original equipment TPC tires, the realized benefits to our customer of inflating their tires with purified nitrogen are expected to be minimal.

I wonder how much longer the 'nitrogen' scam/fad will last and the machines end up in the junk pile behind the shop.

One of the local shops here is still trying to charge 5 bucks a tire

I have to say I am a believer. Try it once and you'll see a pretty consistant reading on your pressure.

I've been using the old-fashioned 78% nitrogen mix on all my toys for more than four decades and get the same results as the 95% nitrogen crowd and it doesn't cost me 5 bucks a tire.

Re: Warranty repair question - can I get the original part back ?

I always used the old fashioned stuff too until General Motors started putting low tire pressure warning on everything. Now everytime it gets cold the monitors go off. Drives me crazy. Like they say, out of sight, out of mind.
Never had to worry about that on any of my old cars !!

Re: Warranty repair question - can I get the original part back ?

The difference in expansion rates between nitrogen and air is extremely small. Tires are not typically filled with pure nitrogen as the air inside them during mounting was not evacuated before filling, so most likely there is still only 80-90% nitrogen. This incremental % of nitrogen will not measurably affect pressure rise as compared to old fashioned straight air.

Further- static tire pressures measured when cold are to a certain degree 'reverse engineered' by the OEM to ensure that the final operating pressures when at normal operating temperatures are achieved.

If it were true that nitrogen expands at a rate substantially less than air, a time may not achieve the desired running pressures on the highway, ie always running too low.

Re: Warranty repair question - can I get the original part back ?

I took the pressure down to 32 PSI and all seems to be fine. I have always followed the label on tires so I didn't even think about looking at the door label.

Thanks for the tip.

Mark, I worked in a chevrolet dealship for about 10 yrs, as one poster said they hold the parts a given period of time, the factory rep. for gm would sometimes float around a certain zone to the gm dealerships and would audit warrenty claims, this was a inspection of the replaced parts. once done the parts were scrapped, so my advice is for you to talk to the parts counter guy and ask him to maybe save the old parts, maybe even bring him a cup of coffee.
