Recently,

I have been losing air in my tires. No holes or anything. I will come out of my house in the morning and one of my tires has almost gone comepletely flat. But when I fill it up, it fills fine and no problems. Has anyone else had this happen to them?

BTW. They are the OEM Goodyears, and I have about 35k on them

If it's only one tire, than it's not your "tires" losing air. Obviously there's a leak somewhere. First check the valve stem - use a lot of spit. Then, just look very carefully for a nail hole, or more probably the nail is still in the tire if it's a slow leak. Again, if you find a suspect hole or cut, use a lot of spit. Our local Discount Tire Store repairs flats for free even if you didn't buy the tires from them - good will for future customers. LOL.

I thought it was just one tire, but it has happened to 3 tires!

i suspect that it is the valvestems most likely. i have one that leaks occasionally. they are cheap.

try the soapy water test if you have time. if not, just go to a tire place and they will immerse the whole wheel to find the leak, be it valvestem or nail.

Or maybe one of those mischieveous gremlins in the neighborhood? :-o

yeah dem kids

And then again, maybe Goodyear has a new system of wear indicators. Instead of the wear bars showing on the bottom of the tread, at 35K miles the tires just start losing air...built-in obsolescence.

I'm at over 39K miles and 2 years (Feb. 03) and haven't experienced rapid deinflation like that. Over months/miles my tires naturally lose air but never like that. I also have the oem Goodyears. I expect to go 45-50K easy on them. Then I'll replace them with the Goodyear Fortera's (stock on the Acura MDX)

I had a (new) rental car one time that had low air in both tires on one side. When I touched the valve stem to fill them up, I heard hissing! The valve stem had been incorrectly installed in the wheel. It must have been a new employee at the factory and every car that day had them bad on one side.

Good luck,

Could be any of the things above. Also dealing with tractors alot,
if you get dirt between the tire bead and rim, it won't seal properly.
Doesn't happen with cars often, but just something to keep in mind.

I honestly think the best solution for this is to get new tires. After Christmas. I've had my eyes on a new set of yokohamas
