Base Coupe tire pressure

Down here we can enjoy the weather until about the 1st week of November. After that its miserable until March. 4 months of actual winter. Sometimes we get almost no snow and other times we get 2 feet. It's hard to say. I should have the Jeep up and running by then tho.

Here in NYS we're good til early-mid November -- whenever the first time they salt the roads is. March can go either way. I wait until after the last time they salt, then we get rains to wash it away, sometimes goes well into April like this year. Either way I'm fine with it. The only people it bothers is people who live in the south.

I can't believe we are still arguing over what the correct tire pressure should be on the C6.
Bottom line ... It's 30 PSI (cold) no matter what brand tires you have.
For you folks that feel you need 40 PSI in your tires ... go ahead ... it's your tires ... do what makes you feel happy.
Just don't come crying here on the CF saying your car has a hard ride, or the center section of your tire tread seems to be wearing out faster than the outer areas of the tread.

BTW ... For you folks that think 40 psi is a better idea .... My advice to you is to fill them to 50 psi ... If 40 psi is better that 30 psi, 50 psi would be even better yet !

From Michelin.
Pulling up your vehicle, we show your tire sizes are P245/40ZR18 for the front and P285/35Zr19 for the rear. If these are your current tire sizes, recommended tire pressure would be the 30psi for both front and rear tires. The pressure shown on the tires is the max pressure, not recommended tire pressure. Which means the tires should never be inflated over that shown max pressure. We hope that your issue has been resolved or addressed to your satisfaction. If we can assist you further, please respond to this email or call us at 866-866-6605 (toll-free) between 8:00 a.m. and 8:00 p.m. EST Monday through Saturday. Sunday 8:30am - 4:30pm chat only. We appreciate your business and thank you for choosing Michelin. Sincerely,

I usually put about 78.09% nitrogen, 20.95 oxygen, .93 argon, .039 carbon dioxide, Plus some misc other gases. It has worked fine for years.
Costco will put nitrogen in you tires for free.

A bit of science as explained by a mechanical engineer. I'm glad that I found this video because it confirmed my viewpoint on the subject. It's also quite funny because I went to a Barrett-Jackson auction a few years ago and at every turn was someone flogging their miraculous N2 products for tire inflation. I had more than a few lively exchanges with them.

Driving to Costco for free nitrogen is ridiculous. I fill mine to 30 psi cold with plain old air from my compressor. Yesterday morning I was getting ready for a 400 mile round trip so I checked the tire pressure. After setting for about three weeks the rears still had 30 psi and the fronts had 29.5 each.

Agree with all the others that have said 30pai. The other day my sensors were indicating my rear left was low, so I stopped by our local Big-O to have all the tires checked. I asked the young kid to ensure they all had 30psi; almost as soon as I pulled out, got a high tire pressure warning on my DIC. Drove straight home and checked the pressure -- the kid had filled them all to just over 40psi, so I lowered them all back down to 30.

It's important to remember that just b/c a shop/store carries/sells tires, that doesn't mean that the staff use accurate pressure gauges. I use high-quality analog and digital gauges that are about 1 lb psi differential to check tires of all my rigs after a "tire store" checks pressure. Two weeks ago, I found all four of my Audi's tires were 8 lbs over -- after taking the rig in for a regular "balance check."

Autocrossing and road racing, always started at 32-34 and tires would heat up to 40ish which worked fine on track. Fresh mounted tires need to be 30 PSI. Oh, and might check lug torque, too.
100 lb ft is correct. I've seen 130+lb/ft. I've only seen one dealer (NTW way back)owner was a racer.
