One of my tires pressure keep dropping to 28-29 psi. The tire workshop cannot find any leaks. But the strange thing is it never dips below that 28-29 psi.

If you are loosing pressure there must be a leak. It could be a nail that has gone in and out, which is hard to find. A leak around the bead or the tire valve. These must be investigated. My money is on a tiny hole made by a small nail, this will be hard to find unfortunately.
