2018 Vs 2014 Platinum wheels
 

will the wheels from a 2018 F150 Platinum fit an 2014 F150 Platinum? Both are 20", 6 bolt

Yes they will fit, same bolt pattern.

Wheels will fit, you just can't use the lug nuts from the '15-18' model year trucks.

As others noted they will fit (and have the same rim spec's - width, center-bore, lug pattern, etc.), the gen'13 (2015+ lugs can't be used (different thread), however .....
.

• due to a change in the lug seating, the lugs will stick-out slightly more. *cosmetic issue only.
• the TPMS sensors are not compatible - you will need TPMS-12 sensors (verses the gen'13's TPMS-35).

.

will fit just fine
