I've searched every combination of wheel/offset/fender/backspacing/etc to no avail. As you can see from the pics, the PS front wheel/tire is even with the fender (as are the two rears). The DS front is no where near flush with the fender. In fact, it sits about an inch or so inboard vs the other three rims/tires. I pulled them all today while checking the break pads and was hoping to find wheel spacers, but didn't. Measurements taken from midline of truck to back of each rim reveal no anomalies. I'm stumped. Did some 16's have different backspacing? It rides and handles fine, it's just not very aesthetically pleasing. I can take additional pics if these aren't sufficient. This is an '01 if that's crucial. Thank you.
