Did you order the TPMS kits from Tire Rack? I've found that some aftermarket wheels can't be fitted with oem style sensors. They either don't work or they leak (badly). When my 18x8 Konig Deceptions were first installed, the TPMS light went off and several hours later all four of my tires went flat. I had to pump them back up (with a bicycle pump, talk about a work out!) and head right back to the Discount Tire. They had to use different TPMS sensors because they wouldn't sit flush with the rim.
