Here's my strory:

I bought 4 new Dunlop Signature Sport tires and had them installed. Shortly after I noticed a small leak with the left rear tire. I had taken the tire to three installers and nobody could find the leak for me. I had them re-bead the tire, submerge it under water(not a single bubble) sealed the tire again, and even checked for rim and valve damage. Nothing worked so I decided to contact the supplier and they replaced my tire.

So far the second tire is doing the same thing. When I drive on the tire it increases preassure by 1-2 pounds while the tire heats up but when I let it sit over night or drive in high elevation it looses air. I don't understand if it increases pressure when driving, how is it still leaking? I am totally stumped on this one. The other three tires are working fine. Any suggestions?

go over it with soapy water mark it take it back in. have them clean the rim to and give it a good surface to bead to.

How much pressure is it losing overnight? It's possible that it could be a tiny hairline crack in the wheel itself. I've seen this on more than one occasion in the tire shop I work at.

They did that when I got the first tire and it started leaking. It slowed the leak but still continued.

A hairline crack on the wheel itself huh? Would that be covered under warranty, or woudl I have to buy a new wheel?
