305/55R20 on 2012 2500 MC stock rims. *NEW RIMS*

Cooper Discoverer AT3 on Stock Longhorn rims. Stock suspension


The pic of the control arm; the shiny spot is from my old tires (285/60/20), the darker spot is from the new tires.

Nice, so the 285/60/20 rub with the factory wheels? It's only a 33.7" tire.

How bad is the performance degradation with the bigger tires??? I'm think about the exact same thing myself...looks great!!

Any big impact on mpg??

They shouldn't, stock size for 20" wheels is 285/60r20. At least on mine it was. No rubbing on my stock 20s. I've got enough room to easily go up to a 295/60r20 on stock and not have to worry about it.

Yes, the 285/60s were rubbing at full lock.

It's never gotten great mileage 13.5, mixed. With the new tires its around 12.5mpg unloaded, 10mpg when pulling my 16ft cargo trailer.
