Leaking wheel?

I'm having a problem that's driving me crazy. Almost a year ago I purchased new tires because they were getting long in the tooth and one of the tires was beginning to have a slow leak, which I attributed to the tires age. The same wheel still has a slow leak which appears to be getting worse. The tire store has taken the tire off the rim, cleaned the bead and put the tire back on with a new valve twice, the second time using a sealant on the bead to make sure this wasn't the problem. The wheel looks straight without any dings or divots, and does not appear to have any cracks. It's still leaking and beginning to get worse. I've had the tire submerged to check for leaks and we can't seem to find any. Has anyone had problems with 2005 Linear 16" wheels? I do not see any posts regarding this, but it can't hurt to ask.

I purchased my 2005 9-2x Linear in June of 2014 with 106K on the clock. I replaced the tires at 131K and I now have 138K on the clock. As you can see I do not drive very much.

Thanks, rj

Re: Leaking wheel?

How fast are you losing pressure? I'd expect submerging it to show the problem, this is something you can do at home as well. There are only a handful of culprits here.

Re: Leaking wheel?

You've done the things I would suspect.  Most slow leaks that I've had were attributable to a foreign object in the tire.  Spraying a soapy water solution on the tire tread, valve stem, and bead is a good way to find a leak.

Re: Leaking wheel?

I'm losing about a pound a day. With the weather we are having here along the shoreline in Connecticut, 40's to 50's one day and 20's the next, I lose about eight pounds a week whether I drive the car or not. I check my tires pretty much once a week or every time I go out, filling it with a compressor I have. I've used every method I can think of. The only thing I can think of is a leak from a tiny crack behind a spoke that doesn't show up clearly when dunked in a tank. I've checked the valve stem, new one when tire was put on and another new one when tire place checked it the last time. Since the problem with a slow leak with a tire on this wheel started before the new tires, I'm beginning to believe the wheel is the culprit. FYI - Since I knew I was having a problem chasing a slow leak on a tire I marked the rim before new tires were put on. So I'm pretty much left with surmising the problem has to do with the wheel and not the tire.

The lack of any information about problems with wheels leads me to believe this is not a common happening, and I think I've done everything to eliminate anything but the wheel. So now my quandary is to purchase another Linear wheel or purchase all new wheels and have the relatively new tires installed on them.

Thanks, rj

Re: Leaking wheel?

You need to squirt soapy water on the wheel to show small leaks.

Re: Leaking wheel?

The spokes do not have air behind them, so the leak will not be there.

Soapy water is great for finding small leaks in the tread, but less effective for finding hairline cracks in a wheel barrel or at the valvestem.

The solution here is to put 55-60 psi (what every the tire lists as the MAX PSI) in the tire and fully submerge it. make sure that the cap is OFF the valvestem before doing this. 8 psi per week pressure loss will absolutely present underwater as a stream of microbubbles. I guarantee it - your average tire shop is staffed with primates incapable of basic troubleshooting skills.

Re: Leaking wheel?

I used soapy water to find a bead leak. Like the OP, I was also losing a pound a day.

Re: Leaking wheel?

I've decided to purchase another 9-2x wheel or upgrade to a set of non-stock wheels. Since I have eliminated the tire or valve stem as being the cause of the leak, I can only deduce that the cause lies in the rim. I've checked in to what it would take to fix a crack if I could find it, and the cost of the repair and being without a wheel for a period of time exceeds the cost of a single rim. A different wheel or wheels would seem to be the most prudent course of action.

Thanks for everything, rj

Re: Leaking wheel?

That's a reasonable approach, if the wheel is cracked you don't want to be driving on it. You should be able to source a single wheel, they were also used on Imprezas for a couple years.

Re: Leaking wheel?

Purchased a used 9-2X wheel and had the tire changed over. No more slow leak!! I still have the old wheel. I have looked at it and can't find anything that would cause it to leak. Oh well.

Next time I go down to my old stomping grounds I'll have to bring the wheel to a friend that has Magnaflux equipment to see if I can find the source of the leak.

best regards, rj

Re: Leaking wheel?

Use the old wheel as a hose winder. Glad you sorted it.
