View Full Version : Older tire leaking air

Hey I have an older 33" tire that slowly leaks air, no nails or punctures. I'm getting tired if filling it every couple of days. Any solutions aside from a new tire?

it is prob not the tire, take it to a tire place and have them clean the corroded rim where the bead sits nad put a new valve in it

I've taken it to them 3 times still no luck, though cleaning the corrosion might be an idea idk if they have tried that yet.

Valve stems/mounting hole? I've been fighting leaks there since last year. Either rust or just cheap valve stems. Soapy water sprayed on the suspect areas should help you find it.

Like Hubs mentioned put dish soap in a large cup & mix it a bit & make sure the tire is filled... then pour it on the tire... if it's a slow leak give it a min. or two & a clump of bubbles will form... sometimes you can hear it if the leak is large enough... if it isn't noticeable then pour some on the valve stem or around the bead or rotate the tire a bit and repeat...once you've located it you can plug it if it's on the tread... or take it BACK to the tire shop...

Any thoughts of filling with Nitrogen?

the air we breath is 70% nitrogen... why would you want to fill it with nitrogen specifically?


do you know WHERE its leaking from? id dismount the wheel and clean up the rim. i take a wire wheel at low speed to mine on the inside of the rim where the bead would sit as i spin it once around the mounting machine. replace the valve stem and use that tire cement around the bead. works like champ for me. if it still leaks... throw that bitch in the fire and stop waisting your time trying to "make it work". even a spare needs to be reliable.

Nitrogen doesn't change it's volume with temperature as much as air does. So it's basically for people who are too lazy to seasonally check and adjust their tire pressure. Maybe even through the course of day, one tire in the sun the other in the shade, driving on the highway vs town, whatever. Maybe there is a GOOD reason to use it but I am not aware of it. I don't think it helps with leaks.

X2 on the soap water. Find the leak and take it from there. You can put it in a spray bottle to make it easier. If you want to get fancy, add a little glycerin to it, or just look up a recipe for bubble solution.

Do you air down to wheel ?? Wasting $$ if you use it & air down...
Some types of racing and such sure, but in something that might be aired down a few days after filling... pass.

As already stated,try Nitrogen,one of the reasons is that the nitrogen molecules are larger and wont permiate the rubber.
Other than that you just need a new tire,pony up!

Ya I know it is old but still has quite a bit of tread left. I was hoping this set would get me through this wheeling season.

If the leak is as slow as it sounds what about setting it in one of the little kiddie pools filled with water and you'll be able to see where it's coming from.

I had it dunked today at a tire store and they couldnt find anything. Im at a loss with this one.

Have them put a tube in it. Problem solved.

No dish soap ??

Would dish soap show more then a dunk tank? I was under the impression they would both provide the same results.

It allows YOU to be in control... I'd also wet the tire first... I've seen guys dunk a tire & not give the tire the attention needed...
How long does the tire take to become low... a day... a week ??
Even if it has been a relatively small leak once the tire was wet & then the soapy water applied in a minute or two I'd have a golf ball size mound of small bubbles... SHOULD it be around the bead it'll foam/bubble there also... the stem might be a little tougher, but not too much...
I've probably plugged 20+ tires using this way to locate the leak...

I have a 35 inch ssr radial that leaks slowly at the bead. Im pretty sure it has some sand or a small pebble in there. My plan is to take of the tire, let all the air out and take my air gun and blow any debris out.

lets say that dosent work, can you really put a tube in any tire? mine say tubeless, but I think all radials say that. If you can do that, why dosent every offroader just run inner tubes>

It takes about 5 days to reach 13psi. I pulled it apart today to check and clean around the bead. Found nothing with the dish soap.

Must be that neighbor you use to bother soooo much... they sneak over under the dark of night & burp some air a few time a week... (done it a few times to a friend in Baja... :laugh3: he had a flat each morning...;))
Steel wheel ??? As mentioned tubing it might be an option... we used to tube tires decades ago, there was the possibility of sheering the valve stem off when aired down and tire tech. progressed...
Where you laying the tire down flat or vert. ? You check both inside & outside sidewalls ??
I've never not found the leak...

If its leaking thru the sidewall,your never going to "SEE" it!

I don't know the details. But I've had tire shops suggest putting tubes in my damaged tires and I've taken them up on it and it worked for me.

AFAIK it causes more heat due to friction between the tube and sidewall. So maybe drive slower, adjust your tire pressure, I'm not sure. I'd ask at your tire shop. I did a little googling and found at least one person running tubes in tubeless tires at the race track without problems: http://www.alfabb.com/bb/forums/giulietta-giulia-1954-65/150019-tire-tubes.html

Not sure what the advantage offroad would be? Tubes are very weak. Anything that damage or unseats the tire is probably going to damage the tube also.

Ya they are steel wheels, we will see what happens over the next few days. It seems to be holding air for the time being.

If the tire isn't for your daily driver, you can use green slime tire sealant on it. I wouldn't use it on a daily driver, because it's a fairly heavy, viscous goo and will throw the tire out of balance(but it does work!).
If it is your daily driver, and you've exhausted all your other options, try using a can of fix-a-flat. Everybody hates that stuff, but if nobody can fix the tire for you, try this:
Jack the tire off the ground(so you don't unseal a bead) and let the air out. Dump a full can of pretty much any brand(it's all the same) of fix-a-flat, air the tire up(a 33 will still below) to about 5psi below your normal running pressure, and take the car for a drive. Run it for about 20-30 minutes. The run time is to distribute the sealant all over the inside of the tire. Leave it for a couple of days, then air down and refill the tire a couple of times. You do this to purge the blowing agent that the fix-a-flat used to fill the tire. No open flame/smoking while doing this. Most tire seal products use methane or some other flammable gas as a blowing agent.(guess where the bad rep comes from)

The fix-a-flat will seal a leaking bead and small cracks in the sidewalls. The green slime will seal everything except tears and rips. We use it in our golf carts, and the tires are so weathered/dry-rotted that one of them weeps the slime through cracks in the sidewall, but still holds air.

The main advantage of nitrogen(commonly called "dry nitrogen")for tires is that it is guaranteed to have no condensation moisture in it. It has nothing to do with leak-proof through bigger molecules. Oxygen molecules are bigger then nitrogen, although not by much. They're only one number apart on the periodic table. When you compress "air", you get the moisture in the air too, and it condenses out under pressure.(that's why we have to run moisture filters for air tools and purge water out of compressor tanks)
In theory using nitrogen gas will also prevent any dry-rotting from the inside of the tire: no oxygen inside the tire to oxidize the rubber. In reality, if dry-rot becomes a problem, it's going to start from the outside(much harsher environment)

One more note on the sealant: Don't use any type of sealant if you use airsoft bbs to balance the tire. The sealant will glue the bbs to the inside of the tire, then it will be WAY out of balance.
