Switch back to summer tires

[SELAWD2011]

Hi

 

I'm up in Canada and I'm about (anxious) to switch back from steelies to mags. I want to do it myself but I had two questions:

 

1- TPS Sensor:

Do these need to be reprogrammed or will the system simply recognize that they are back on now?

 

 

2- Torque wrench

My buddy has all the tools required, including a torque wrench which he says is required to secure the mags back in place. Is this true? and if so... does anyone know what the presure needs to be (he claims 50 lbs).

 

 

Thanks

The typical Ford spec for lug nuts is 100 ft/lbs, NOT 50. You don't have to use a torque wrench but it helps a lot to be sure you're getting even torque.

1. Yes, the TPMS sensors will have to be retrained to your car.

Your buddy's got his head up his ass if he thinks 50 ft/lb's is an appropriate setting. It's 100 as noted above, and it's a huge safety concern to have it done properly. The other thing is you should tighten them one across from each other to even out the force on the rim. I've been doing it myself (rotating the tires) for years and it's simple. Make sure you do it safely with jack stands. Mark the tires so they go in the proper (rotated) place next winter. Use white chalk. The TPM's will reset as mentioned.

Cars are typically ~75 ft-lbs but yes the Edge is 100.
