My 99 4Runner seems to have constant air pressure loss in the tires. I have to even out and put air in about once every 2-3 wks. Anyone else having this problem? Any easy fixes without causing other issues.:sosad:

The first easiest way I'll do is to look at the tires and see if there's a nail anywhere. If couldn't find anything, I'll put some soup water onto the tires and see if bubbles are found anywhere. If so, that means that area is leaking air....

I think you mean, "soap" water not, "soup" water.
You can also use Formula 409 household cleaner, it will bubble up where the air is leaking.
You could have a leaky valve stem, or something between the rim and the tire (my sister in law put her Lincoln LS is the ditch last year and some grass got caught between the tire and rim causing it to leak). Id bet that its most likely a nail in the tire, an easy fix (as long as you have a tire patch kit).

Leaky tires

If it was just one tire I would have done all that stuff. However it's all 4 "tires". Two are a little worse than the other 2 but they all slowly leak. Don't really want to fill the tires with that stop leak stuff for flats, that stuff really creats a mess on the inside of the tires if you ever really need to have a nail puncture fixed.

Its possible that whoever mounted the tires didnt do a very good job. Id try soapy water or 409 and see where they are leaking.
