I was making an inflation chart last night and stumbled upon a problem.

Like most front wheel drive cars, the Aveo is front heavy. I did a little research and came up with 60/40 (front/rear) weight distribution for a front wheel drive car.

Well the problem is this. GM says to inflate the tires to 30 psi each. But the front tires support almost 300lbs/each more than the rear ones. Wouldn't the front tires require more pressure than the rear tires?

After reading some more, it would seem like the opinion of many is that most car manufacturers do not make good recommendation and that more psi is needed.

I also stumbled upon the rule of MAX -10% (In our case this would mean 44psi - 10% (4.4) = 39.6 psi). A guy had about four cars and tried it and it worked out to about 1 or 2 psi close to where he likes to run his tires. Last summer I ran my tires at 37 psi, no problem, put 6000 miles on them and I can't see anything suggesting overinflation wear.

What do you guys think?
