Just doing a little browsing of my '07 Owners Manual ...

High-Speed Operation CAUTION:
Driving at high speeds, 100 mph (160 km/h) or higher, puts an additional strain on tires. Sustained high-speed driving causes excessive heat build up and can cause sudden tire failure. You could have a crash and you or others could be killed. Some high-speed rated tires require inflation pressure adjustment for high speed operation. When speed limits and road conditions are such that a vehicle can be driven at high speeds, make sure the tires are rated for high speed operation, in excellent condition, and set to the correct cold tire inflation pressure for the vehicle load.

If you will be driving your vehicle at speeds of 175 mph (282 km/h) or higher, where it is legal , blah, blah, blah ...

This is marketing genius (though stuck into an Owners Manual) ... not quite to the Viagra 4 hour warning, but not bad ....

I'm surprised someone reads the manual.

I increased my tire pressure from 30 psi cold to 32 psi cold when I did my laps around Talladega Superspeedway. I figured it would help to have the pressure a little higher. I guess my average speed was close to 100 mph, and up to 152 mph on the back straight. But it was only 5 laps at a time, with temps in the 80's.

Must have been a fun 12 miles!

I'm not sure you shouldn't adjust the air pressure lower??? With the heat and speed, tire pressure increases...could it get too high? I'm asking cause I don't know.

I stayed at 30 psi cold and did 4 sets of 5 laps at Talladega ... top speed 158. broke 150 many times. rock solid exiting turn 2 between 125 and 130. (2010 coupe)

Throw that book in the garbage. Only kidding.

Actually the warning has merit. Especially for the uninformed (which means the vast majority of drivers) about higher speed driving. Here is a link to a Tire Rack Tech Article on adjusting tire pressures for extreme high speed (which all Vettes are capable of achieving):

As you can see it can get complicated.

So there you are, getting around to reading your 2007 Owners Manual - it's only June 2013 - what's your rush ??!!

Bill, thanks for the link. Very interesting.

That's great stuff! For those times when you need to get up above 175.

Once again....great sense of humpor......I may yet have to drive up there and do the helium thing...lol.....

100avg....I don't know we got pretty slow in the front and turn 1 and 2.... I was seeing 5lb increase by tpms at the end of the laps.....your tires were sticky enough as I caught plenty of tiny stones from you.....it was nice meeting you.

But to be fair to GM, that line in the manual would be completely valid for a C6 that lives in Germany...and lots of them do.

You forgot to mention the tires should be pumped up to 37 psi if maintaining speeds of 175 mph
It's in my Warranty book!

My tires were at 32 psi when I got to Talladega but never thought to check them after my runs. I got over 150 mph numerous times with no issues.

I personaly counted well over 150 Vettes at the track and I did not see anyone bleeding or adding air to their tires. I also didn't hear of anyone having any tire problems or flats, and most everyone hit triple digits...with alot of guys hitting a buck fifty+.

Most manuals these days have a lot of text that seems to be aimed at reducing liability claims. That example sounds like more of same.
