 Subject: Proper Tire Pressure
IP: Logged
Message:
Related somewhat to my discussion on the spare tire subject, I was also wondering about the proper air pressure I should maintain in my Goodyear Eagle LS 255/65R15 tires. The door panel suggest 35psi, but I have a feeling this particular pressure may be for another set of stock tires, because I notice my Dak skips alot if a hit a bump moving laterally, as if the tires are a bit to rigid.
What do you folks think? I thought 32psi might be better.

I believe the MAX PSI COLD is 35 for most tires, unless they are heavy duty which may be higher. Most shops generally inflate to 32 psi COLD, since the air will heat up and expand once you are driving.

First, never exceed the maximum cold pressure on the sidewall.
After that, check your owners manual. Mine came with a big addendum about tire inflation pressures for various sizes. Figures for 255/65R15 show 35psi for front and rear for both lightly loaded and fully loaded conditions. It also says to increase pressure by 4 psi for continuous operation over 75mph, but not to do that with anything more than a light load: 2 passengers and 200 pounds of cargo.
You can fine tune your inflation pressures for maximum tire wear, fuel mileage, ride, and grip. Each will be a trade-off and are best done by trial and error.
You can also get a head start by inflating the tires to whatever you think they ought to be, cold. Then park the truck on a straight, flat, smooth, quiet road. Draw a thick chalk line straight across the tread of each tire. Now drive a hundred yards or so and get out and look at the chalk lines across the tread. If they are worn away evenly the pressure is fine. Worn away more in the middle of the tread means the tires are too hard. Worn away more on the edges means they are too soft.
That will give you a good baseline. Adjust from there to suit yourself.
cheers,

David,
I would suggest that you replace the Goodfernothin's as soon as you can. They don't run well in hot weather. I had 2 explode on my Dak in the first 5000 miles. My bud had 1 and neigbor had 1 explode the same way- out the sidewall. I wouldn't drive them over 60 if it gets hot where you live. I replaced mine with 275x60x15 Goodrich T/A's. They are 1/10" shorter but wider.

I noticed the Goodrich tire you're speaking about on Tire Rack when I was searching for tires. They're significantly cheaper and I have heard good things about the tire.
I've ran Goodyears all my life on the cars I have loved most, though. I've never personally had a problem with them and I still think the tire was damaged by the previious owner.
SO when tire purchasing time comes, I'm not sure which one I will go with.

Not sure what you mean by laterally? Laterally I thought was moving sideways or in some cases reverse, as in a lateral football pass.
If your truck can move sideways, I want one of those. It would sure be easy to parellel park.

Well if you moving laterally on bumps you may want to look at getting new shocks. I had a similar problem with my dakota and got new shocks all around solved the problem and firmed the ride up nicely.
On the tire pressure issue I believe the Eagle LS say a max of 44 psi cold on sidewall? You could lower the psi on the rear tires a bit and see if that helps but 35 psi is what I usually run my rear tires at and I think it rides fine.
But if you skipping a lot on bumps at 35psi I would definitely look into your shocks.
