what is the tire PSI supposed to be?

[johnwc723]

okay i thought it was supposed to be 26 but it looks liek lots of people got it at like 36, inside the door i tought it said 26 but it was kind of wearing off...

[nswst8]

Its posted there for each specific tire. I like to run mine 32-34 PSI since a air expands when hot, its said that you will gain about 4 PSI after driving a short distance.
But adjust your PSI according to your tire wear, driving prefs, loads.
Hope this helps, LOL.

ahhh what an imbigous answer!!! ohh well yeah i think than 26 is probably too low then, you get a better ride at the higher psi tho anyways i think?

[nswst8]

If you are going to use big words, you'd better know how to spell them and their meaning! Another word for ambiguous is vague, and I don't believe I was being vague, evasive, uncertain or unclear in my description of how to evaluate correct or manufacturer's recommended psi. My daughter can locate the psi on the side of her bicycle tire, for crying out loud, and she is only 8. Though the manufacturer suggests 36 psi for my vehicle's tire, I clearly outlined the method by which I prefer to inflate mine, and the reasons why.
Hope this helps, LOL

i wouldn't recomend to run below 28 psi. i ran 30psi on my car. it says that if you do a lot of high way driving increase the pressure by 4 psi. 26+4=30.

[AZmike]

The pressure listed on a tire's sidewall is typically the maximum safe pressure, not the recommended pressure for all vehicles using that tire. Each vehicle lists the manufacture's recommended pressure on the doorsill. Runnnig higher than 26 psi will give you a little harsher ride and a small increase in fuel economy. I usually run 30-32 psi.

[k-roy]

Ok when you check the tire pressure you better do it while they are hot
if you max the pressure on cold and then heat them up it can lead to problems.

[johnwc723]

alright, and by the way there nswst8 the tire pressure is NOT the one on the tire (that is also a MAX PSI) as much as it as what is reccomened in the door panel for tire size and PSI (the reccomened in the door is worn off on my car hence the question) bicycle tires are alot different than automotive tires (intertubes and such) ask your 8 yo to tell you what the reccomended tire pressure is for your car

[NXRacer]

if you're running a smaller tire then stock, you shouldnt go by what your door says. You'll ruin em. Every tire has the PSI pressure on the sidewall you just gotta look. I always go by what the tire recommends, not what the door says.

[johnwc723]

ahh wtf thats not what my auto tech teacher said!! i guess yes, if your tires are exactly what is specified in the door then you use that psi, however you dont want to use the one printed on the tire thats usually "max psi" well at least on my tires! ahh its a crazy tire world out there

you should never go by what it says on the tire. why do you think Honda put 26psi number there.

[johnwc723]

thanks for the help everyone, who knew that tires could be that complicated!

[nswst8]

We always have an opinion and are always willing to share it with anyone who cares.

I run 26 in the front and 30 in the back. then again i do a lot of city driving with my car.

[johnwc723]

hmm why the difference in psi from front to back?

[HondaBoy]

most of the tires i have put on my car say that 44 psi is maximum. a good pressure is about 35. i notice my gas mileage is worse when tires are lower than 30 psi. it rides a bit better too, feels firmer and more comfortable when its about 35 psi. my yokohama's are good at 35 psi. also my 02 accords tires are good about 35 psi. i aired them up today. they were down at 28 psi and there was i nice difference aired up right.

[soljaboy2000]

i keep mines at 30 cuz my tires aren't that top notch

[Busted_Blue]

hmm why the difference in psi from front to back?

I guess i use parts of the sidewall for grip (ghettttoo!!!), course it probably decreases treadwear as well gas economy....ah well, perhaps i'm just mentally thinking it feels better in grip.

[A20A1]

I've set mine to 26-28 since we've been having a lot of wet weather lately cause the stock tires on my corrola just love to slip. Mostly I like 30... btw max psi on the tire is 40.

I got better tires on the accord... so they get 32-34 psi wet or dry.

[johnwc723]

i guess ill set mine at 32, mine are SHITTY AS HELL and have a max of 36 i think heh!

[keruhas184]

So, I put 17s on the car today. The tires are rated for 44psi max, and were inflated about 40psi. The ride was very harsh.... Now I'm running 35psi, and its much better.

Can I go down to 30 psi on 205/40-17 tires? Few people told me that because the low-pros don't have too much rubber to start with, they can't bounce like our stockies, and they need to be inflated to at least 38psi. Is this correct? I would really like to know because at 35psi the ride is only bearable...

[IWLSF]

I run 32 in the front, 34 in the rear. The sticker on the door is for the tires that came from the factory. Not all tires are made the same, so unless you're rolling the tires that came from the factory 17 years ago, dont follow those specs. Higher the pressure will be a harsher ride, whereas lower is softer. But lower gets less gas mileage as well.

[keruhas184]

Yeah, I know about the door sticker. My question is: can I run low profile 17" tires at 30psi without damaging the tire or the rim?

[Vinny]

I run 40-42 psi with 17's . Just my 2 cents

[keruhas184]

Ok, 32 psi (cold) seems like a good compromise. That's what I'll be running unless someone can prove that I'll damage my rims if I don't have higher psi.
