You're good. Probably wont ever use it. Make sure you have practice using the plug-kit and test out the compressor

I have the same setup, still haven't gotten around to actually putting it in the car.

 

I'm not taking a stance either way, but Fix-a-Flat seems to believe their formula doesn't screw up your TPMS.

"Fix-A-Flat® is a simple solution to a flat tire. It seals and inflates in minutes! Just connect the hose, inflate, and you will be back on the road in minutes. Shouldn't everyone carry a can of Fix-A-Flat® in their vehicles, just in case?

Safe for tire sensors
Requires no tools or jacks
Non-flammable formula
Safe to store in your vehicle's trunk or tire well
Rubber compound provides an emergency seal on contact
America's #1 tire inflator and sealer "

 

I run w/out a spare and enjoy having (almost) a normal trunk.
Fix-a-Flat is velcroed where the spare used to be.

 

I just remove it on track.

 

Do not use fix a flat that stuff sucks to get off the inside of the rim and tire, it can also destroy your tire and rim if left on for more then a few days.
