One of the wheels on my 2002 Grand Cherokee has a very slow leak. This leak has persisted through numerous tire mountings, valve and tire replacements, and two US Presidents. I am convinced the problem lies somewhere with the wheel itself. The leak is very small- it takes a couple weeks to even go down 2 or 3 PSI. It is just a big enough problem to be seriously annoying.
I can come up with 3 repair options.
Buy a new wheel, throw away the old one, and be good to go. This is a few hundred bucks.
Buy a cheapo wheel and use it for the spare (which has the same wheel as the other 4). Mount the current spare on the vehicle. This probably costs less than $100.
Use the leaky wheel as a spare, and keep a couple cans of fix-a-flat in the vehicle. If I ever get a flat, and don’t just end up calling AAA, I can just fill the thing up and change it.
The Jeep never leaves the road, and with 160K miles on it, doesn’t really ever get all that far from home. I don’t remember the last time I was more than a 20 miles from a reasonable sized metro area, complete with AAA tow trucks.
What do folks think? I am tempted to go with option 3, just want to make sure I am not being stupid.
