As much as the TPMS message pisses me off that it doesnt clear itself off my MFT screen, I will live with it.
Also I usually check my tire pressure every other fill up so it doesnt bother me as much just the annoying message.
Yeah I was basically in the same situation, I opted to not get TPMS (luckily Tire Rack will still sell us tires without them... If you go to a brick/mortar tire ship it's apparently ILLEGAL to not install TPMS on tires). I also got the wheel/tire coverage from Ford (but not the extended warranty). In Michigan, if they keep not passing road funding, this will pay for itself probably 5 times over

, I'm already a little nervous about the potholes I've hit just in the first few weeks of ownership. One thing about the tire warranty I was worried about is if they will try to not cover the tire if it doesn't have TPMS.
What do you mean it doesn't clear itself off the MFT screen? Mine pops up in the middle and beeps, then it goes away about 5 seconds after it pops up. And yeah, I don't need TPMS on my winter wheels, the sidewalls are gigantic, and I check them at least once a week.
