I am looking to get a set of 16x8 Eagle series 102's and get rid of my FX4 wheels this winter. I will be putting 305/70/16's on them (basically a 33x12.50x16) but don't want the tires to stick out real far like I see on a lot of trucks. The ad says Offset: -20mm, Backspace: 3 5/8inch. So what is stock? I'm kind of ignorant to the whole offset/backspace thing so any help would be appreciated.

BTW, there isn't anyone out there in the Pacific Northwest who would want a set of FX4 wheels, is there? I will have no need for them once I change over.

 

Stock backspacing is 4 1/2 inches on the OEM 17x7.5 inch wheels. Therefore the Eagles will stick out about 1 1/2 inches farther than your stock wheels.

 

Thanks, I guess that doesn't seem too bad. Just didn't want the look where half the tire is exposed outside the fender. That's why I'm sticking with 8 inch wide rims also.

 

if your truck is stock you're gonna have to do some trimming as well as get rid of the inner fenders.i've got 33x12.50's and i have my torsions cranked all the way and i had to trim the front valance and cut a lip off the cab to keep em from rubbin so as long as you're not tryin to keep it in mint condition and own a sawzall you'll be good

 

You shouldn't have any problems fitting the 33's on 16x8's. According to his sig, he has 15x10's. If that is correct, the 15x10 Eagle wheels in the 5x135mm bolt pattern only have around 2 1/2 inches of backspacing which will make the wheels stick way out. Also, before anyone asks, it is possible to fit 15's on 97-03 F-150's. There were a couple of companies that made 15's to fit 97-98's, but they had very little backspacing. The same wheels would fit 99-03's (which used larger brakes) if you ground down the brake calipers. Because of the low backspacing and fitment problems, it is much better to stick with 16's or larger.
