Leaky wheels/tires?

[Papa Weeley_imp]

Is anyone else having a problem with their tires losing air? Mine lose about 2-3 lbs. per month. Luckily I check them fairly often, but this seems like a lot of loss for that short amount of time. And it's both the front and rear at an even rate, not just one, so it's not like there's a leak in just one of them.
Just curious if that's the "norm" for these cast wheels?!

Mine do the same, maybe even a bit more. I check them every couple weeks and put a couple pounds in. All my bikes do that - cast, spoke, new, old - so I never really thought much about it.

My tire pressures go up and down with temperature changes which is normal.

I would try making a heavy soap solution using dish washing detergent and brush it onto the tire bead areas and valve, wait a while as this solution will stick quite well and should reveal any small leaks. Next I would try soaping the tires and then the wheels. A soft brush works well for this.

That's quite normal.
Even my other tubeless tire bikes and tubed bikes lose air and I have to top them up as needed. I check the tire pressure every week.
My car tires also lose air over time.

Normal. Car tires do the same.

Normal. If you had a leak you'd lose more than that in a DAY.
Now you know why they tell us to check out tires weekly.

I have to add air about every other ride, which is every couple days, for all three bikes.

Yep, mine too.

When new, they leaked a fair amount more, but as (I guess) they seated on the rim the loss settled down to your rate.

My car did the same thing when I got new tires.

The colder it gets, the more they leak. You could get some bed-liner and paint the insides of the rims with it. Very light coat. Then remount and re-balance the tires. Pain in the butt but no more leaks. Cast wheels are often slightly porous. YRMV.

You can actually buy Bead Sealer at your local auto store. I used it on some lawn mower wheels, but never on my vehicle tires as I have a shop mount them.
