Proper air pressure for Limited wheels???

[iLLWiLL]

I have an '07 SR5, and i just put on Limited (18" six-spoke) wheels with BFGoodrich Long Trail T/A (265/60R18) tires.

what is the proper psi for the Limited wheels with 265/60R18 tires? I checked and apparently the tires came set to 35-36 psi


thanks in advance

Follow the sticker on the driver's door jam. Your SR5 tires and Limited tires should use the same PSI.

Yes, Thai is correct in that the recommended pressure is the same for all wheels, which I think is 32 psi.

I think they ride better at 34-35 psi, though.

Thai - I would be careful with that door jam sticker... That got Ford into a lot of trouble a few years back. If you read the sidewall of the tire, it should state the recommended maximum pressure for that tire. You should never exceed that pressure, but you should also never be at highway speeds with a tire less than 30 psi.

32 PSI (all 5 tires)

34 psi for the best ride:cheers:

 

[iLLWiLL]

hmmm...yea, 32 psi is what i thought. I think i'll go on the safe side and go by the book, 32 psi.

thanks fellas

Did you swap out the spare rim too? I would keep the 16's in case you want to go off roading. Just a thought.

no i kept the spare rim underneath

i was planning to see if i could sell the 16's/tires to a local shop. But perhaps i should keep them for off-roading (that is, if i ever plan to do it), thanks. Off-roading on 18's isn't good?

Off-roading on 18's isn't good?

I'm sure you'll do fine with 18's. I was just suggesting the notion that with a higher tire sidewall with the 16's you're probably less prone to scratching those really nice 18's while your off pavement as they are gunmetal coated too aren't they? It's like keeping your 16's for some good snow or off-road tires for those wheeling trips. You'll have an easier time too finding some good dirt/wheeling tires for the 16's too if you plan to use your truck in that way in the future. And if you scratch up the 16's, no worries.

Great idea I probably would not get much money (especially from a shop) for some stock 16's and tires anyhow

You've got to be careful with the sidewall, too. That's a rating that's an absolute maximum, without considering the weight or size of the vehicle the tire is mounted on. You can't just read the sidewall and forget the sticker, or you'll probably be running too high. There's a happy medium in there somewhere.

Personally, i would not even tough the sidewall ratings. Stick to Owner's Manual and door jam sticker.

 

[Uneek]

I run 36psi in mine for pavement use.

 

[Jacobzky]

34-35psi always.

 

[Koz]

40 psi from day one. I wish these (OEM Bridgestones) would wear out, but they still look very good (almost 30K).

I run my Dunflops at 36 psi. Still have over 1/4" tread left after 31k miles.

that's exactly what cost Ford so much money and grief. They had on the doorsill to set the tires to 26 psi for the best ride. When the tires dropped to 24 with the weather/pressure changes, they became totally unsafe at highway speeds.

I think the best answer is somewhere in the middle. I would never run any tire at it's maximum rated pressure, but I tend to trust the tire manufactures more than the auto maker since the auto maker (Toyota in this case) uses multiple types/sizes/brands of tires for the same vehicle.

What cost Ford was bad rear susp design for that vehicle.

Actually, for Toyota vehicles that i have seen/owned, there are different pressures for different tire sizes.

true...and for these tires, the max is 35 psi.

I'm at 31-32 psi right now (difficult to get it exact). The problem was the gas station i checked it at yesterday read 36 psi. But when i checked it with my own instrument, it was about 29 psi. Go figure...


by the way, does it matter whether or not you check the psi when the tires are hot or cold (just recently driven, or parked for a while)?
