ive had my 2k3 maxima for about 3 months now and im trying to figure a good air pressure for the tires. ive always been told to ride on about 35-36 psi in the tires...wanted to know what your guys' preferences were..

 

its in your owners manual...and on the underside of your armrest...and on the tires
there is no reason to run anything different with normal driving. i only add more when i auto-x.

 

Also depends on the tires you run.

I ran the OEM crap at 33PSI, while I run the Conti Extreme Contacts at 36PSI because of the softer sidewall.

 

FYI,
a poll for something like this is pointless since there are so many variables. people are voting but not posting an explanation. the majority may say 35-36 but you wont know if that means stock tires or something else.

 

Stop being such a "bully"...

 

im not a bully...i "tell it like it is"

the bully thing started as an old joke but newbies took it as me being the self proclaimed "org bully"

 

Well, then stop telling it like it is...

Don't you know that people don't like to come onto a public forum and be told something negative.

What are you going to do next, call someone a ricer.

 

i tell the truth...if its taken negative then that person needs to take constructive criticism better.

stop whoring this thread!!!

 

ok ladies, simmer down now....


lol






Anyways, I keep my tires around 33-34 PSI during the winter, and 34-35 during the summer....

I dont go over 35, too many times a year...

(Ever since I had some work done at Tire Discounters and those idiots filled my tires up to 40 PSI during a snow storm........I didnt have my gauge to check there f'up, so I went out that night and ended up doing a 360 in the snow, on a very sharp off ramp!.......Luckily, I got it out before anyone could really notice.... )

Ok Cobra21 what tires and wheels are you running, I can help you. I sell wheels and tires for a performance shop and based on experience I can help you. There are alot of variables that come into play when talking about tire pressure. Like the kind of tire, size of the tire, width of the tire as compared to the wheel width, sidewall hight of the tire, weight of the car, what type of driving do you do (freeway, city, track, ETC...), is it lowered and ETC... Most of the people on here will tell you to look at your owners manuel, but that only applies to the factory tire and dose no good for your aftermarket tire. For instance a factory brodgstone should be ran at 36psi for best wear but if you put a toyo on your car, factory size then it should be run at no less then 40psi. so let me know what you have, size, brand, wheel, and if its lowered.

 

toyos at no less than 40??? i run mine at 34

 

mine takes 51 psi but i keep 45

 

i have kumho ecsta spt's on my car

 

I think tire pressure will vary by manufacturer and by owner. I run Kumho Ectsa ASX's on my stock rims at 32 PSI.

 

37-39 psi.

 

Winter : Front=37psi, Rear=35psi (1psi for expansion)
Summer: Front=34psi, Rear = 32psi (4 psi for expansion)

All above is cold psi!!!

 

depends on what tires you run, how much weight you carry, and what kind of driving you do.

I run mine at 35f/33r

 

i got a set of goodyear rsa's on mine. what should i run? im a pretty aggressive driver

 

Im running Toyo's on my car soonerfan and I run 40psi at all times. Toyo has informed us for daily driving you want to run 40psi for the best wear, performance, and to get the best life out of your tire. If you are looking for a great ride and you have toyo's go ahead and run 35psi but the tire will not last as long and wont perform the way toyo intended.

Now here is a tricky one, what speed rating is your tire platinum03SE? The RSA depending on the size comes in alot of different speed rateing's. What I would recomend is take a look at the sidewall of your tire and see what the maximum tire pressure you should run is and go about 4-6psi below that. This will allow some room for the tire to flex in the corners but not to much that the sidewall rolls under.

The Ecsta SPT's are a AWESOME tire!!! I would recomend running those at 39-40psi, its a vary high performance tire at the top of the Kumho line up. They are not cheep by any means and even just to get the most life out of them I would definitely run that for pressure.

Also listen to irish44j, thats someone with racing experience and knows there ish44. (excuse the pun on your name irish44j no disrespect ment just thought it would be funny)

 

like everyone's said, it really depends on the tire and its size. the exact same tire model may perform differently in a different size. for the oem bridgestones, i think i did 36/34 IIRC, it was so long ago. i remember for the falken ziex 512s, i ran them at nearly 40 psi all around and really liked the way the increased pressure affected response. I didn't experience any traction issues either with that high of a setting because the falkens were pretty damn sticky in my opinion. i currently am riding on general exclaims (245/35/19) w/ about 35psi all around and the ride and response is pretty decent. of course, if they were stock size, i'd probably want more pressure...

 

revtohard im gonna check what they are, thanks for the info.



ya uhmmmmm

kumho ecsta spt's > all

 

This the best advice, IMO:

Yup, in a nutshell.

This thread hits it in more detail, so dig out your pocket protector and load up the calculator with some fresh batteries if you really need to know.

IMO, 40 psi is way over the mark, anything over 38psi (hot) is compromising ride and feel and the ride will be crappy, bouncing all over the place. I bet this puts a lot more stress on the shocks!

 

My manual calls for 33F, 32R.

However, I am running either 36F/35R or 35F/34R depending on how often I check the tires.

This should result in better fuel economy and tread wear, perhaps at the expense of a modestly stiffer ride (which I can't really notice with my stock SE suspension).

Yokohama Avid H4S tires with 5,500 miles on them.

 

It depends on many things (primarily on the tires and their size)

I keep my Toyo Proxes 4 225/50-17 at 39psi all around. Back when I had stock Potenzas I ran 35psi both front and back.

 

as well.

here's some stuff about tire pressure. http://www.tirerack.com/tires/tiretech/tiretech.jsp

 

35 F/r .

 

I've got 245/35-19's, it says 51psi max on the sidewall. I run around 45-47psi.

 

Whoa. I have the same size tires and I run 35 psi. You're a bit high IMO. You should stick a bit closer to the OEM recommendation. They base that on the weight of the vehicle, not the tire size. That is what the Tirerack guy told me.

 

Also have the General Exclaim UHPs (245/35/19) and have them set at 35psi all around.

 

 

34-35 psi on my Yokahoma Yk 520's.

 

I always thought you should run lower psi on your front tires for better traction and higher psi in the back because they are not turning. I'm basing it on that the front tires are doing the work the get the car moving.

I'm running 32f/35r. Toyo 4s all around.

Need opinions... am I wrong?

 

you need more up front due to weight distribution (engine weight)

 

Agreed

 

I'd say it varies with the brand/model of your tires. I have always set the tire pressure minus 6psi from the maximum tire pressure marked on the sidewall. My current tire's max psi is at 44psi. I keep the tires set to 38psi. I just don't like the way the car feels/brakes/handles at anything less than 35psi....again, it depends on your specific brand or model of tire and driving preference.

 

man i listened to a friend that said run the oem tires at 40 psi and then 3 days later i blew a tire on a pothole. funny how when you think someone knows what there talking about because they worked at town fair tire, they dont. but then again thats the place that broke 4 lugnuts off by puting them on to tight....

 

that's also happened to me but it was only one lug...and I didn't find out untill my tire went flat and I tried to put the spare on. The lug that broke was the last lug that didn't want to loosen so I forced it - snapping it clean off. It's happened to me before on a company van so I knew the snapping was inevitable. There I was rolling on a donut, in the front, with one of the front wheels held on by only 4 lugs. I took my car back to the tire einsteins the next day, complained, and they repaired it all for free. All this happened after I specifically told the head tire einstein to torque the lugs to 90 ft/lbs. (oem recommended torque) I never went back there again. A lot of shops are too lazy to adjust the torque of the impact air tool because they have to walk allll the way back to the compressor. So instead, they set it to a universal 110+ ft/lbs so that no matter the vehicle, it will be "tight enough" that the wheels don't fall off while driving. I think shops with better air tools can change the torque right there on the gun.

yea yea

 

I've personally had nothing but excellent service out of discount...maybe thats only in atlanta...lol
