Gotta leak in my left rear tire, cars only got 36xx miles on it, and theres nothing in the hole, just wondering if anyone has had this problem as well? Factory tires, factory rims, nothing changed.

Just glad we have the TPMS otherwise I wouldn't have known : /

 

I had a slow leak in my 07and took it back to Mazda because of the TPS (no one wanted to fix it) and it turned out to be the sensorwas leaking, no charge because it was under warranty[8D]

 

If the sensor checks out as OK (you check the tire pressure with a gauge and you are indeed low), then I'd pull the wheel off of the car, fill your bathtub with water and dunk the tire under water. If there is a leak path, you'll see bubbles rising from it.

If there is a hole in the tread portion of the tire, that's easily repaired using self-vulcanizing tire plugs. I've used them for years on dozens of vehicles without a single one coming out (get the black ones that come with the adhesive pre-applied.) Any autoparts store should carry a basic kit for under $10, a larger kit ~$20..

 

We found a good sized piece of metal in it today, it was very slim and all the way in the tread so we couldn't feel it!

But we pulled it out, plugged the hole, filled the tire and that was about 2.5 hours ago, checked the tire pressure and it hasn't leaked at all yet!

Thanks for the replies guys!
