Default Tire pressures for z06 wheels on c5?

I think the previous owner said they were Z06 rims, & I can't find out what pressures to put in them,
but here are the tire sizes;
Front; 245/40 ZR 18 97Y
Rear; 285/35 ZR 19 103Y

Hankook Ventus V12 evo2

Those are C6 base wheels that appear to have been coated black. C6 Z06 wheels would be split spoke and wider in the rear.

My guess would be to see what is recommended for PSI on a C6. Probably in the 28-30 PSI range.

Well.. my door sticker tells me 30# cold, always worked for me. Pretty sure your car will say the same.

There is a sticker on the door body pillar that shows what the factory rcommended tire pressure should be. It's 30 psi cold. Having C5 Z06 wheels or C6 wheels won't make any difference. "Cold" means the tires haven't been driven for a few hours. A couple of pounds of pressure one way or the other won't make a real difference in general street use so start with 30 and then adjust to suit the conditions.

The door sticker is just a generic sticker...it means relatively jack squat...in your cold temps i would put in 28-29 to get it to the sweet spot of 30-31...in the summer maybe 26-27 to get it to the sweet spot of 30-31...it all depends on your ambient temperature and what kind of roads and city or highway driving you do...so you can figure it out this springtime where you live and put in a certain pressure then drive for a while then see what it registers hot and make adjustments...
If you put in 30 in the summertime the pressure could go up to 36-38 hot and that is not good in many ways.

There has been so much heated discussion in the past 10+ years about correct tire pressure...everyone thinks they are correct...especially the people who swear by the generic fake news door sticker....anyway i'm sure this thread is going to stirr the pot once again...

Be careful who you listen too...all the above info is my take from you know who ...and maybe we will even see a guest appearance from him giving you the lowdown......come on in Boy....i sure hope he chimes in...

Chalk test them. Itís a very popular way to set pressures in the off-road when running larger tires.

Basically you make a thick line of chalk across the width of the tire tread and then drive a few rotations. If the chalk has been scrubbed off evenly, pressures are dead on. If the center goes first, lower pressure, if the edges go first, increase.

Not Corvette related but tire pressure related.
Why does my Eagle Talon TsiAWD door sticker say 32 psi for the front tires yet 28 psi for the rears? It's all-wheel-drive and the tires are all the same.

Whatís your weight distribution? Are they nose-heavy? It can also be to get certain handling characteristics out of the car.

Simple answer. front tires bare more weight because more weight is in the front on the Talon. the numbers, 32 psi and 28 psi is a formula of the load bearing and the tires load baring load spec. you can find that max load number on the sidewall of the tire. load divided by two. for max load, but the weight of the car is the load. the max load is the amount of load the tire can carry. divided by 2 for the talon,, divided by 4 for the Corvette.

the reason the corvette has similar front a rear psi because the load ratio front to rear is 50/50 meaning the 4 tires bear the weight of the car evenly.

I know a few things because I studied

Ok...
So now let's get back on track about what tire pressure is correct for our C5s...like "sweet spot"... etc...explaination of why to use it instead of the generic door sticker so many people are relying on and believe in...we need facts...ok BOY...even though you have explained it a million times and I have been using your info successfully for 10++ years...can you please post it again for the newbies...the best tip I have used all these years...i said, I said... thank you BOY...

Because the explanation always brings argument and train wrecks, its hard to offer facts to people who got their education from their grandfather who work at a gas station back in the 50's. Be happy In the fact that you know the difference Kenny, not everyone is so gifted with friends that know stuff.

I don't get this. If you have better info to offer, why keep it from the masses?
I've found that 30PSI cold works great, any higher and it gets darty. So yes, if set at 30 cold, and it gets crazy hot, that ain't gonna work.
I see cold as low miles from starting out. A long trip (which I rarely do) might just get it too high.
I just set mine on the way to work every couple weeks.

Yep....can't blame ya Bill...you always get a horse stable full of crap when you posted the tire pressure explanation for the last 10+ years and I just may post it for new members to see if i can find it...but here's my feelings to those who have in the past given you unnecessary crap about the real deal explanation...here's what i wish i could tell them without a fight....but i'm too chicken..

The tyres do not know what vehicles they are fitted to.
your hand book will give recommendations for the various sizes wheel and tyres fitting to your model.
I have seen a lot C5 with much wider tyres that those listed above
