tyre pressure for 2nd gen

Use the tire manufactures tire inflation recommendations. They are moulded right into the side of the tire.

It can be checked with the tires warm but the tire makers usually put the check tires cold to allow for expansion when the tires do become warm. I think that for every 10º f. you should expect 1 psi rise in pressure.

The number molded into the sidewall of the tire is the MAXIMUM pressure allowed for the tire itself and NOT the pressure recommended for the car its on. If you run the max pressure all the time you will get a hard ride and most likely wear out the middle of your tire/tread. The maximum pressure would only be used for a car with a full load like 4 passengers and luggage. Use the pressures recommended on the sticker in the drivers side door jam.You can adjust the pressure up or down to compensate for your driving habits. I would start with 30# and adjust from there.

I personally like a harder ride. The better I feel the road, the better I can adjust with the changing road conditions. At least I believe this to be true.

I check my tire pressure regularly and can't remember any time that I've ever had a tire wear in the middle. I'm not saying what you state above isn't true, just that I've never run acrossed it.

The factory(GM) recommended pressure, as printed on the door sticker, for my

4th gen SS/M6 equipped with P275/40ZR17 tires is 30psi. The pressure(maximum) molded into the sidewall of my P275/40ZR17 BFG G-Force T/A KDW Z rated tires is 44 lbs. Quite a difference there. I too like to feel the road, just not every pebble on it and I don't like the feeling I am riding on steel roller skate wheels. So since I never have my car loaded to the maximum gross weight limit, I only run the recommended 30 lbs. I don't claim to be an expert on tires. What I stated was common knowledge that anyone can read in there owners manual or on any guide to" tires and tire pressure". Also building tires for Goodyear Tire for the last 16 years, I have learned a thing or two. Why do I run BFG over GY's on my SS ? They are simply a better tire for the way I drive.

my 2 cents... [according to my manual] the faster you drive on the hwy. the more tire pressure you need. On a 'z' rated tire, the 44 psi is for speeds in excess of 100 mph.

Thats odd. I have a manual for a 2000 Camaro, I assume you are using a 2000 manual since your sig says you have a 2000 Camaro, and it doesn't say that at all.

Bullshit ! Where does it say that ? If you had read all of the manual you would also have also read the following..........

(Quote) If you'll be driving at speeds(e.g.,speeds of 100 mph (160 km/h) or higher), where it is legal, set the cold inflation pressure to the maxium inflation pressure shown on the sidewall, or to 38 psi (265 kPa), whichever is lower. See the example below. When you end this high-speed driving, return to the cold inflation pressure shown on the Tire Loading Information label.

Example:

You'll find maxium load and inflation pressure molded on the tire's sidewall, in small letters, near the rim flange. It will read something like this: Maxium load 690 kg (1521 lbs.) @ 300 kPa (44 psi) Max. Press.

For this example, you would set the inflation pressure for high-speed driving at 38 psi (265 kPa). (End Quote)

.............Now I can see setting your pressure @ 38 psi for a high speed run, Higher pressures give you less rolling resistance. However, its gonna corner like shit!

Read ALL your manual and stop giving out your uninformed information on here that can damage someones car and even get them killed. If you want to run the maxium inflation pressure on your car, go right ahead. I will out E.T. you and lose you in the twistys.

Why does jbrainey have to be such an asshole.??? Maybe he was born that way. I never said I was quoting the manual word for word... DUH.!!!
