Hi,
I was wondering if anyone has downsized from the 22'' rims for winter tires..because those scor zeros absolutely blow in the winter. I was hoping to go to a 18" rim, but i have 2 different answers from ford. The service department said i can only downsize to a 20' with 275/55/r20s and when i asked the parts counter sales person, they told me that 18's will fit over the calibers.

Im looking to get some nokian studded hep7's... has anyone done this to a 20125 HD on here with some advice maybe?
