2005 Cavalier Tire Pressure

[evildragon]

I've tried for countless hours to get this information, and it's an emergency..

What is the tire pressure for these cars? Someone had me fill it up to 40PSI which I did NOT want to do, but they insisted. This person drives a child in this car, and I'm worried about their safety.

I feel it's about 30PSI. Cause my Caprice is 35PSI, and I can't see this Cavalier having higher PSI than my B-Body car.

Should be stamped on the tire, and on the door jam or door pillar.

The tires only say 44psi max presss, and the door sticker has oddly wiped off it's ink.. So the column that would state the tire psi is all blurred.

You can do what you want 30psi.

I would do what the tire says - 44psi. Your gas mileage will be better, tires last longer and wear evenly (that's the safety factor), etc., ...

35 psi always worked for me and my two kids survived !

Low to mid 30s should not be an issue.

I second inflating them to the max pressure on the sidewall. PSI is pounds per square inch, and I bet a caprice has more square inches. My truck with 35" mudders on it "looks" ok with 20 PSI in the tires, but 35 PSI "looks" low with the 235/85/16s on there.

Runing a tire low is MUCH more dangerous than runing it over inflated (anyone notice all the melted RF beads at Martinsville yesterday?, not saying they were underinflated infact it was the braking that caused it, but underinflation causes heat... don't want that happening without the "safer barier"!).

I'm certainly not recomending that anyone try it, but I have had the tires on my car well above the max pressure with no problems.

it is safe to run up to the max pressure stamped on the sidewall, and it will improve milage. If the max is 44 then 35 would probably be fine but the milage and performance will suffer. on the other hand the lower pressure (35 PSI) will give a smoother and quieter ride. With the price of fuel I always run the max pressure. the manufactures probably have a large safety margin before the tires would become a risk for rupture. I don't advocate it but I have also personally ran higher than max when I had a slow leak and wanted to refill less often (I know not a good idea but what else you gonna do when you are a broke student and don't have money for tires).

Tire pressure should be set to the manufactures spec. Most likely its somewhere around 32 psi. The tire pressure on the tire is the MAX PSI for the MAX LOAD that the tire is rated for. Running them at that pressure will not hurt them but it will do two other things. It will give you a smaller footprint which results in less traction which leads to increased braking distance. It can also lead to the premature wear of the center tread.

I Agree!!! Anyone that says you should run what is on the tire doesn't know what they are talking about!!! Go to any tire manufactures web site for conformation on this and for more information about the pressure and load information on the tires sidewall.
