Front right tire looks deflated? - General

I only just noticed this now, is this normal? The tire looks deflated but feels fine, it doesnt look like it's fitting the rim correctly. [IMG]http://i39.tinypic.com/op5pj8.jpg[/IMG] [IMG]http://i40.tinypic.com/2lx8jcy.jpg[/IMG]

Did you check the pressure is set correctly?

lol, just check it, a tire pressure gauge is like 99 cents from an auto parts store

I'm not even sure what it's supposed to be set at. There was problems with that side awhile back from the previous owner who curbed it and fucked up the axle. But I have since then put 1k+ in it and have gotten it fixed.

...it says on the tire what to set it at..

Alrighty thanks, will do that tomorrow

I just go to some tire shop and tell them to gauge my tires.

You don't have to be a car person to know to use a gauge and test the pressure if the tire looks low. As l_l said, a gauge is a few bucks at most.

Your tire looks deflated because it IS slightly deflated. You don't have to be a rocket scientist at NASA to figure that one out. They have air compressors at almost every gas station i've been to, and they usually sell 99c air gauges inside the store.

Take it to your local Discount Tire, they will not only air it up for you for free but also fix it if it has any sort of nails or punctures in it (for free)

I've seen some vehicles look like they are low but really they are at the manufacturer spec. Its just the way the weight of the vehicle sits on them. Just get a tire gauge OP, so you aren't that one person that puts 20 PSI in their rear tires and 70 in the front because they look full that way.

It took me 45 minutes of ripping my hair out trying to explain to my girlfriend over the phone how to use the air pump at a gas station. Ever since then I've accepted that some people just don't understand these things.

[QUOTE=lemon_lover;34565706]...it says on the tire what to set it at..[/QUOTE] Actually i wouldn't go by this. The one printed on the tire usually states what the MAX pressure is. You can find the correct pressures in your vehicles manual/handbook.

The pressure listed on the tire is the pressure reccomended for the best load and tire efficiency. Inflating it to the "max PSI" listed on the tire is the point where you get the best economy out of the tire and loadbearing capacity. Over that will increase fuel economy but too far over will increase center tread wear and make the tire unstable. We're talking 60PSI in a 44PSI tire though. Personally I run 40PSI in a "44PSI MAX" tire, and 32 in a "35PSI MAX" tire. I do sometimes run 45PSI or 38PSI when the tread is close to its end, to maximize life of the tire by minimalizing the contact patch.

[QUOTE=lemon_lover;34565706]...it says on the tire what to set it at..[/QUOTE] or you could check the PSI sticker usually found on the driver's door hinge area

Not everyone has the same tires as what came with the car off the showroom floor. It's easier to look for the giant, impossible to miss, raised lettering that says [b]44 PSI MAX[/b] right on the side of the tire anyways. And even if i did have the same rims and same tires as when my car came out in '87, it doesn't show the psi on the sticker anyways. Hell, it doesn't even tell me what kind of car it is...I have to look on the firewall under the hood on the stamped piece of metal to see that. And it doesn't show the tire psi there, either.

Justin, I hate to tell you this. Your car is a hovercraft.

Eh, 35 psi seems to be a pretty good number for almost every car on the road today... maybe 32 or so in the winter to get a little extra bit of treat on the road.

35PSI in a 44PSI tire is not enough.

Most tires are rated for around that, and running them at that pressure will give you shit for traction in the winter. The 30 series tires on my 20's are rated for 45, and running them at that pressure is like riding on bricks. 35 is much better. I've never seen a passenger car that called for over 40 in the door sticker.. and these tires are basically no different. Even light duty trucks don't call for much.

The only time I ever see them go higher, are on commercial vans and diesel trucks that are usually in the 50-80 PSI range.

My drive tires look like this (but not that severe) I keep them about 5-10 PSI under recommended pressure for the winter.

The sidewall pressure is NEVER what you should be using. IF you're using the specified tire size that the designers set for that car, the manual/door sticker pressure is correct. If not, you need to tinker a bit(Easiest way is to drive to a parking lot, put white chalk on the tread lugs, drive it, look at the tracks it made to judge the contact patch, and adjust pressure until the contact patch is right), but it will NEVER be the max pressure listed on the sidewall. The nylon belted 235/75R15 M+S Goodyears I use are pretty happy at the specified 35 PSI, even though the truck came with 215/65R15s stock. I've got aftermarket wheels that are a bit wider, if you're wondering why I'm using the larger rubber. I will say that my tires look flat at all times, but the belts are nylon so they're quite soft. Every tire is different as to how much it squishes. Pretty sure OP's tire is really stupidly low though, 10-15 pounds, but he's likely dealt with it by this point. [QUOTE=Demache;34674613]Ditto. The only time I ever see them go higher, are on commercial vans and diesel trucks that are usually in the 50-80 PSI range.[/QUOTE] The big stuff is often 120PSI and up. 120 is what the tires on my dad's 18 wheeler are supposed to be at.

[/QUOTE] I really have to disagree here. I had Kumho KR21's rated at 44PSI max at all 4 corners on my car, in the stock 205/60/15 size. Subaru recommends something like 32psi front and 30 psi rear, I ran them at 34 front and 32 rear. The tires looked fine, but thousands of miles later the outer tread wore about twice as fast as the inner and 2 of the tires were ruined from under inflation. The pressure in the manual and door is right for the original type of tires rated at the same pressure as the originals, but when you change to a different type of tire rated at a higher PSI, you should really base the pressure on the max PSI of the tire. At the moment, I'm running something like 38 PSI in the KR21's that I have left (they are worn on the outer, but still have good tread in the center) and a different pair on the front of my car at 34PSI. Running my tires at the pressure on the door ruined them, you shouldn't go by that pressure unless the tires you have are similar to the original ones and rated at a similar pressure.

If the tire lost air abnormally fast, fixaflat that motherfucker. Otherwise add air till it perks up and live the rest of your life with the secret joy of knowing that you put air in a tire.

[QUOTE=Super_Noodle;34723365]If the tire lost air abnormally fast, fixaflat that motherfucker.[/QUOTE] If you put fixaflat in that motherfucker be prepared to buy a new tire. I won't even touch a tire for repair if it's had fixaflat in it -- that stuff is explosive. And considering you have to light the glue for the patch inside the tire, this means I run the risk of losing some eyebrows at the least. Fuck that. It also makes the tire soft on the inside so often I can't patch one even if I take and wash it out. Fixaflat is stupid -- Go to wal-mart or some shit, have your shit fixed. It's often $10. Come on.

Airing them up to that will mean, when things have warmed up you're running a higher pressure than the tires are structurally capable of. You're literally rolling on ticking time bombs, a blowout more of a "when" than "If" at this point. In your case some deviation from the sticker may be good, as apparently those Kumhos have far softer sidewalls than Subaru's engineers planned for, but running at 44PSI is just asking for trouble.
