Do I think it's wise?? Although you and some others may not, I don't have a problem with running a 1.25 -1.50" hub/wheel centric spacer with my factory wheels/tires. Heck, I've ran spacers on my two previous 3/4 ton rigs without issue, and, both of these trucks were mildly lifted with aftermarket wheels and 35's; although not heavy (6500lb Jayco), I also towed with each rig. IMO, provided the spacers are from a reputable company (Borla, Goeske, etc.) and not the cheapo Mr. Gasket and ebay cr@p, and, these things are installed correctly and checked periodically, this set up is as safe and no different than buying an aftermarket wheel (of same width) to achieve the same outcome.
To some of you, I started this thread to gain feedback from others on the potential for rubbing or clearance issues, and, opinions with regards to appearance, good or bad. I don't need to be questioned or educated on the pros/cons of wheel spacers; had I, this would have been reflected in the subject title. thanks
I don't think an engineer or FCA would agree with you.........
