I have had 2 new Firestone fuel savers tyres fitted on the rear, and have had problem with losing tyre pressure, I took my car back they put some fluid and found the leak from the rim where the wheel balance weight is fitted, both weights were removed and internal weights fitted, this seemed to solve the problem with no noticeable leakage, but three days later I am 7 pounds down in pressure on one and 3 down on the other.
They mentioned the bead is thick on this make of tyre, could this be a problem and maybe not a good compatible tyre for this car.
MY car is a 1997 BMW 323i 205/60/15 tyre size

The most likely cause of this could be one of two things.
Firstly, there might be a bit of corrosion on your rim which is causing seepage. All they have to do is take the tyre off, clean the rim and put it all back together with a bit of bead sealer.
Secondly, It might be that the fitter has not seated the tyre properly. When a new tyre is fitted it should be inflated to 40psi then adjusted to the correct pressure in order to seat the bead.
A tyre of that size is very easy to fit so it is unlikely to be damaged during fitting unless the fitter was a complete numpty.
Keep taking it back till they sort it

Alloy wheels are powder coated and then sprayed and lacquered. After a few years and a few tyre changes the lacquer breaks and/or minor wear starts.
When a new tyre goes on it does not form the same seal on the rim as the old one. When new balance weights are fitted air usually seeps out. Even after weight removal the new tyres can still lose air. The only fix is to have the rims refurbished, you don't have to have them completely refurbished, just the bead area.
Often the tyre fitter can re-seal them, but this would only be a temporary fix because sooner or later the seal will start to lose air again.

I am assuming you are talking of tubeless tires here. A 5psi drop in 7 hours is a very small leak which would not show up in a regular water immersion test. Immersion in a clear soapy solution overnight might show up the leak, since there would be bubbles or foam on the water in the morning.Most likely the new tires and old rims do not match and there is a seating issue. With a tire pressure of 50 - 60 psi you have more chances of locating the leak. The other possibility is that the leak is somewhere on the thread, which opens up only when the tire(thread) is under load. Only a close inspection of the inside of tire would confirm this.

I would take the car back to the shop that mounted the tires and have them replace the valve stems if they weren't replaced when they were mounted and have them re-seat the bead. Even with a thick beaded tire a wheel wieght will not cause a leak. 7 lbs of pressure loss is a problem and they should fix it at no extra charge.

Have them break the bead, clean the inside sealing portion of the rim, and re seat, using nitrogen (it holds better) Its possible there is some dirt or corrosion on the rim bead that is causing it not to seal properly.

Take your car back to where you had the tires installed and have them clean the bead area of the rim with a wire brush.

it has nothing to do with the tire, the installer is a fault here. have them remove the tire clean the rim and put bead sealer on the rims when putting on the tire. i had the same problem with my 528i.

I'd suggest that you return to the dealer, who sold you the tires. He should have known, and advised you that these tires were not compatible with your vehicle. If he had done so, and you persisted in purchasing them, then the fault would be yours. Since he did not, the fault may very well be his, and he should exchange the tires, or return part of your purchase price.
