Can I use factory tpms sensor with E load tires?

Hello, the tire grade used should not alter TPMS function. So, seems like it should work just fine. Keep in mind that just because the tire allows up to 80 PSI doesn't mean you should inflate it as such. You may have to have some kind of specific recalibration performed - check with your local dealership to see if that's even possible. It could be that you can't reasonably do this swap without unresolvable complications.
