Tire pressure

I just purchased an '02 Ford Ranger 4x4. It came with Goodyear tires, which I was happy to see. Reading the info on the side of the tire, it says max pressure of 44 lbs. The tire info on the fuel door says 30 lbs. front and rear. HUH? At 30lbs. the tires are underinflated. This is the same problem Ford had with the Exploders, I mean Explorers. I've always kept my tires inflated close to the max., for proper wear and handling. Why would Ford be setting themselves up for another lawsuit? I don't mind a firmer ride, it is a 4x4. So I'll keep the tire pressure at 40lbs. unless I hear differrent..... Any thoughts?

You certainly have a good point.

Probably you have purchased an optional tire package - larger tires, maybe heavier duty. The manufacturer usually makes their tire pressure specification based on the standard tires.

I think the 44 psi maximum is also the pressure at which the tire will support its maximum weight rating. So if you are hauling a load it is proper to increase the pressure some, up to 44 psi. But chances are on an unloaded pickup this is too high.

So, I think you are correct in expecting 30 psi is too low. 44 psi is probably too high under most conditions. So you might want to pick something in between that produces good wear characteristics. As you know, pressure too high wears the center, pressure too low wears the outsides.

Like you, I think somewhere in 36 - 40 psi is going to be about right.

They should give customers that buy optional tire packages some kind of additional notice regarding proper pressure. Something that supercedes the sticker in the fuel door.

Are these tires 16". If so, think about it. They're the same tires that come standard equipment on a 3/4 ton or even a 1-ton truck! (even if they're 15", they could be mounted on a 1/2 ton) A Ford Ranger is not that heavy a vehicle. And the payload capacity is no where near that of one of these full-size monsters.
44psi is the ABSOLUTE MAXIMUM Goodyear says is safe to put in these tires before they blow off the wheels on one of these full-size vehicles, FULLY LOADED. So yeah, 30psi seems low, but you probably have a lot of tire on those rims.

Just my humble opinion.

Ford Ranger

SBR I too drive a Ranger, I run my tyres at 38psi anything less and it feels like they're going to roll off the rims.I read somewhere in the manual that fully laden off road you can take them upto 60psi!
Mine is normally well laden and she spends 70% of her time off road and 30% motorway driving.It's a company motor and I can't remember the make of tyre,it's also bloody cold outside so I'll stay inside in the warm with my can of Fosters! Bear

tire pressure

Thanks for the feedback. The tires that came with the truck are P245/75/16. That's a P and not LT. So were talking passenger car tires. There is an optional off-road package that puts 31x10.50x15 on the truck but I did'nt order that. Running them at 40lbs. feels pretty firm, 38lbs. feels better, but I don't want to go any lower. Thanks again.....
