Good Morning, Purchased a new '22 Lariat in July. Im concerned already how the kms are adding up. Considering how low dealer inventory was at the time it took awhile to get me one. Prior to, I asked the sales rep to find me one with 18" chrome wheels. When he found me a truck he mentioned that he switched wheels from another new truck and put them on mine. Could it be possible that the smaller wheel is not proper for my truck and effecting my kms total.

 

Wheel size would have nothing to do with it. Tire diameter would. And if both are factory, then no, I doubt you're going to get any meaningful difference in how you rack up the kms.

 

Look at the tire size presently on the truck, then compare those to the tire size on the driver side door jam sticker.

If there is a difference use the below supplied link to see the difference
