Hello, I have an '87 4000. Purchased the car a year ago and am still learning about it. Question: What should the tires be inflated to? I have Bridestone 205's on the car. They say no more than 40 psi. But I know that those ratings have to be read with just so much salt. Presently I have about 38 in front and 41 in back. Any thoughts?? By the way, I love the car!!! Thanx
