Losing Tire Pressure... =(
I have got my new Black Motorsport rims 18x10.5 17x9.5
And threw on KDW2's 295's rear and 255's front...
Well the 2 front ones are losing pressure usually after 2-3 days they will only have about 1lbs in them or less.. only one rear loses .5 every 2-3 days and 1 tire in rear actually keeps its pressure!
Whats wrong with my damn tires or is it wheels or ... valve stems? There is no nails in the tires so im just trying to troubleshoot.

Fill'em back up with air and then spray some soapy water around the valve stem. If it bubbles, that's where the leak is. If that doesn't work, spray around the bead and then the entire tire.

I would suspect the tire bead. If you have three losing pressure its likely either the bead or the valve stem (including the "o" ring in the pressure sensors.
Use a dilute solution of dishsoap in water.... and spray it along the bead, (both faces of tires)and over the valve stem. You want the leaking air to blow bubbles so you can find the leak

if you have clip on tire weights as I did originally, they were leaking as the tire did not seal the bead properly where the clip on weight was. had them rebalanced with stickon weights and no more leakage.

I'm going to have to go along with the tire pressures sensors. The same thing happened to me when I got my motorsports. Left the tire store, got a mile down the road and got the message low pressure. Went back and they tighted the valve stem down, left again. By the time I got home, the same thing. I tightened it down again, checked the other 3 with soapy water, all of them were leaking!

I've had problems (with other wheels) and it was at the bead.
But at the rate you are losing pressure, I'm inclined to go with the valve stem theory.
Soapy water will give you the answer.
